This paper deals with the response reduction effect by friction under 2-dof system. The friction behaviour is effective for dissipating seismic energy. Therefore, in recent years, the installation of an isolator and a damper with frictional element in industrial facilities has been investigaed. In addition, the seismic response is reduced by the frictional vibration occurring between piping and support system. However, response acceleration of the system becomes larger by stick and slip motion. In this study, the response reduction effect of 2-dof friction system is evaluated by response energy, input energy and response acceleration. The ratio between elastic energy and input energy is utilized. In this paper, "Response reduction map" for 2-dof friction system based on energy and response acceleration are suggested. These map show the area that the response magnification is less than 1 and less than the response of linear system and the energy response ratio is less than the ratio of the linear system. Firstly, the time hisotry response of the input energy, the friction energy, the damping energy and the elastic vibration energy of 2-dof friction system are shown. Secondly, the response reduction map by the artificial seismic wave calculated from the design spectrum is shown. Optimum friction forces for reducing the response energy and response acceleration of 2-dof friction system can be easily obtained by this map without non-linear time history analysis.

This paper deals with design method for Electromagnetic relay in consideration of the contact state of a contact spring under vibration. A contact spring can be described as a beam with boundary condition which depends on the contact force at the tip of a contact spring. However, the estimation of response of the beam is a complex problem. The present study makes the FEM model using element of two-dimensional beam for estimating the opening force at the tip of a beam by numerical analysis. The FEM model can be obtained the response acceleration and opening force under vibration. In addition, the opening force is approximately proportional to the maximum value of input acceleration. Therefore, the estimation method of contact condition can be useful for design of contact spring in Electromagnetic relay.

The frictional behaviour is effective for dissipating seismic energy. Therefore, in recent years, the installation of a frictional isolator in industrial facilities has been investigated. In the present paper, the easy estimation of seismic respose for a 2-dof friction system based on a friction response spectrum and modal analysis method are proposed. Moreover, the applicable range of the proposed method is clarified by comparison with the result of non-linear time history analysis. The proposed method can obtain the seismic response of a 2-dof friction system immediately without non-linear time history analysis.

For the past several years, seismic isolation systems have been focused in the seismic design of industrial facilities. This paper deals with the response reduction effect by friction. Friction is expected to decrease the relative displacement by dissipating the vibration energy. The relative displacement between structure and support becomes larger at long period in the case of linear system. Therefore, the response reduction effect by friction should be utilized positively in the seismic design. However, the response magnification of acceleration is used in the seismic design. The acceleration becomes larger by stick and slip motion. Therefore, the response reduction effect by friction is evaluated from the viewpoint of energy. The ratio between elastic energy and input energy is utilized. In this paper, “Response Reduction Map” based on energy forlong period friction system is suggested. This map shows the range that energy response ratio is less than the ratio of the linear system. The response reduction map without complex non-linear time history calculation caneasily obtain the proper parameters, such as natural period or friction force. In this study, the response reduction map by the artificial earthquake wave calculated from the design spectrum is shown.Next, the advanced friction damper is developed by using above energy based result. The friction part of the advanced friction damper is constructed by using MR fluid. The characteristics of the friction part are evaluated.

Design spectrum modified for long period structure is suggested. Response spectrum calculated by linear analysis using actual seismic waves is different from response spectrum of seismic design for the range of long period. In addition, friction isolator is expected to absorb seismic energy. This effect should be utilized positively in seismic design. However, seismic isolation effect depends on the friction characteristic of system. Therefore, adjustment of frictional force becomes very important. This paper shows Friction Response Spectrum for long period by the synthetic seismic wave using design spectrum. The Friction Response Spectrum is able to obtain the optimum frictional force of seismic isolation instead of non-linear analysis and estimate response magnification of long period system with friction. Moreover, equivalent damping ratio is estimated from Friction Response Spectrum for long period system. Equivalent damping ratio can easily calculate response of friction system.

Design spectrum modified for long period structure is suggested. Response spectrum calculated by linear analysis using actual seismic waves is different from response spectrum of seismic design for the range of long period. In addition, friction isolator is expected to absorb seismic energy. This effect should be utilized positively in seismic design. However, seismic isolation effect depends on the friction characteristic of system. Therefore, adjustment of frictional force becomes very important. This paper shows Friction Response Spectrum for long period by the synthetic seismic wave using design spectrum. The Friction Response Spectrum is able to obtain the optimum frictional force of seismic isolation instead of non-linear analysis and estimate response magnification of long period system with friction. Moreover, equivalent damping ratio is estimated from Friction Response Spectrum for long period system. Equivalent damping ratio can easily calculate response of friction system.

The damage by amplitude increases with the coupled vibration is shown. The response magnification is obtained from natural frequency and damping ratio of the coupled system in the seismic design. Therefore, the natural frequency and damping ratio of the coupled system are required. The natural frequency and damping ratio of support and structure are obtained in initial design or vibration test. However, the natural frequency and the damping ratio of the coupled system are not easily obtained. The natural frequency of the coupled system can be calculated from theoretical equation, but the damping ratio cannot be easily calculated. In this study, the equation to calculate the damping ratio of the coupled system with Rayleigh damping is shown. The equivalent damping ratio without Rayleigh damping is estimated.

This paper deals with response reduction effect by friction behavior. Friction is expected to absorb seismic energy. This effect should be utilized positively in seismic design. For past several years, seismic isolation structures have been focused in seismic design of industrial facilities. Seismic isolation effect is controlled by the friction characteristic exists in friction support. Therefore, adjustment of frictional force becomes a very important. In this paper, "Response Reduction Map" for long period friction system is suggested. This map shows the range that response magnification is less than 1 and less than the response of linear system. The response reduction map without complex non-linear time history response calculation can easily obtain the response magnification. At first in this study, the response reduction map by actual earthquake wave is shown. Next, the response reduction map by the artificial earthquake wave calculated using design spectrum is shown.

Human beings get outer information by the senses, and the function by vision and hearing are the most important in getting them. However, if vision and hearing are not able to work, it is difficult to get them clearly. So a tactile sense can be considered as new information-acceptance organ. In present, there are many experiments in a tactile sensor. In this study, the method of transmitting information using vibration to a tactile sense is considered. Then we picked the sense of vibration at the palm and grasping a handrail, and experimented with vibration at the palm and using the model which imitated a handrail.

Thin plate structures are used to various product structures. They are light and easy to treat. However, to make their rigidity up, it needs to use curved plates or concavoconvex plates, ..., and, to reduce noise sound from plate structures, it needs to attach damping sheet. It has to be clear how to consider basic design philosophy for low vibration and noise of thin plate structures. Then, in this research of noise reduction design for thin plate structures, we study on control to vibration modes of them. And, for a good example, we investigate the transfer function of a steel drum.

A human being can feel signals with five senses such as vision, hearing, sense of touch, sense of smell, and taste. If we rely on vision and hearing, we become hardly to understand signals, in case that information variety or quantity is increased. As a message measure that such a case can get complementary, the sense of touch is thought about. In this paper, vibration signals are investigated. Vibration signal is a vibration we use with special purposes or intentions. Vibration signal can transmit information to a person through the sense of touch. Vibrators of portable phones are one kind of examples. They tell us only arrival of the call. We can not discriminate who call us. If we are able to make various types of vibration signals, they can help the sense of sight and hearing. The purpose of this study is to investigate on human sensitivity of vibration frequency, vibration envelope pattern and of parts of body that receive signals, and to propose the most suitable vibration signal for information.

Intention communication with a different foreigner is possible by a facial expression and a gesture. In this way, the role that a facial expression serves as by communication is very big. The aim of this study is to control a mind state by the intentionally modified facial expression. The final aim is the application to a field of the medical welfare. In this study, measuring the behavior of each muscle of a face using electromyogram in order to evaluate the expression quantitatively elucidates the mechanism of a facial expression. Six facial expressions is paid attention. When a human being made a facial expression intentionally, it is thought that a mind state changes by the facial expression. For example, it is said that a mind state is stable unconsciously when making a smile intentionally. On the other hand, it is thought that a mind state becomes unstable when a partner makes a facial expression of anger. In this way it is thought that a mind state is closely related to a facial expression, but there are many subjects that have not been elucidated. So the relation of a facial expression and a mind state is cleared from bio-information such as electromyogram or brain waves as an engineering approach and will be applied to the medical welfare.

A human being can feel signals with five senses such as vision, hearing, sense of touch, sense of smell, and taste. If we rely on vision and hearing, we become hardly to understand signals, in case that information variety or quantity is increased. As a message measure that such a case can get complementary, the sense of touch is thought about. In this paper, vibration signals are investigated. Vibration signal is a vibration we use with special purposes or intentions. Vibration signal can transmit information to a person through the sense of touch. Vibrators of portable phones are one kind of examples. They tell us only arrival of the call. We can not discriminate who call us. If we are able to make various types of vibration signals, they can help the sense of sight and hearing. The purpose of this study is to investigate on human sensitivity of vibration frequency, vibration envelope pattern and of parts of body that receive signals, and to propose the most suitable vibration signal for information.

A human being laughs in every day life when happy, and a facial expression changes unconsciously. It is thought that the facial expression has close relation to feelings and Kansei. The facial expression is more intelligibly than the expression by word, and can convey a delicate nuance when introducing feelings. Intention communication with a different foreigner is possible by a facial expression and a gesture. In this way, the role that a facial expression serves as by communication is very big. The aim of this study is to control a mind state by the intentionally modified facial expression. The final aim is the application to a field of the medical welfare. In this study, measuring the behavior of each muscle of a face using electromyogram in order to evaluate the expression quantitatively elucidates the mechanism of a facial expression. Six facial expressions is paid attention. When a human being made a facial expression intentionally, it is thought that a mind state changes by the facial expression. For example, it is said that a mind state is stable unconsciously when making a smile intentionally. On the other hand, it is thought that a mind state becomes unstable when a partner makes a facial expression of anger. In this way it is thought that a mind state is closely related to a facial expression, but there are many subjects that have not been elucidated. So the relation of a facial expression and a mind state is cleared from bio-information such as electromyogram or brain waves as an engineering approach and will be applied to the medical welfare.

This study deals with the experimental and analytical procedure for the dynamics of fly line. The casting is one of the most significant issues on the fly-fishing. The flies are the aquatic insects that imitate mayfly, caddis fly and stonefly. Anglers cast these flies for the area where fish are found. In order to present the lightweight flies, the weight of fly line is utilized for casting. The loop shape of the line while it flies, fling speed and casting process are important for the proper presentation of the flies. Moreover, the shape of fly line is also the important element for the long cast or the control cast, hi this report, fly-casting process is investigated experimentally. The fly line and rod system is modeled and calculated by using multibody dynamics.

The dynamic characteristics of piping system installed in industrial facilities have to be recognized as one of the significant issues in economic and safety design consideration. Piping systems are generally connected to supporting structures at several points by means of devices such as guides, spring hangers, hydraulic or mechanical snubbers and certain energy absorbers. When friction damper attracts attention, the amount of energy dissipation at contact surface is restricted, because the maximum displacement of sliding motion is limited by the clearance of the equipment. In order to increase the amount of energy dissipation, the ball screw type magnetic friction damper is proposed. This damper is expected to increase the energy dissipation by converting one directional motion to rotating motion by ball screw. In this work, the fundamental characteristics of proposed damper are clarified. The numerical model is made considering parameters obtained from testing, and the results from simulation are compared with the results from testing.

In this paper, the basic characteristics of "Ball Screw Type Magnetic Friction Damper" are investigated. "Ball Screw Type Magnetic Friction Damper" is a kind of friction damper. Ball Screw is used to increase the sliding displacement by changing translation into rotation. Restoring force occurs mainly by friction force between rotation disk and fixed disk with permanent magnet. In this study, a small product of the damper is made. The characteristics of the damper are examined by the results from shaking test and the results of numerical analysis. The numerical model of this damper is applied the damper to one degree of freedom system in order to investigate response magnification of this system. Permanent magnet is changed into an electromagnet to control the resting force. Possibility of the damper as a semi-active one is investigated.

This report deals with the experimental and analytical study of seismic response behavior of piping systems in industrial facilities such as petro-chemical, oil refinery and nuclear power plants. Piping is generally put on the supporting structures. Therefore, frictional vibration occurs between piping and supporting system during seismic excitation. Special attention is focused on this nonlinear frictional dynamic responses of piping systems due to frictional vibration appearing among piping and supporting devices. Two mock-up piping structure models are excited by large scale shaking table. FEM models are made from the mock-up piping of shaking test, and modal parameters of linear system are calculated. The time history responses are calculated by nonlinear response analysis using calculated modal parameters. Friction response spectrum are proposed to calculate the maximum responses having frictional behavior. The maximum responses calculated by friction response spectrum are compared with the maximum responses obtained by experiment.

This report deals with the experimental and analytical study of seismic response behavior of piping systems in industrial facilities. Piping is generally set up on the supporting structures, therefore when shaking motion is given, frictional vibration should take place between the piping and the supports, and two dimensional sliding motion occurs. A three dimensional mock-up piping and supporting structure model is excited by large scale (15m×15m) shaking table. First mode and second mode of FEM piping model are calculated independently, and maximum responses and dissipated energy considering the frictional behavior are compared with the responses obtained by experiment. The process to calculate the response of friction system is evaluated.

This report deals with the experimental and analytical study of seismic response behavior of piping systems in industrial facilities such as petro chemical, oil refinery and nuclear power plants. Special attention is focussed on the nonlinear dynamic responses of piping systems due to frictional and collisional interaction among piping and supporting devices. A spatial mock-up piping and supporting structure model wherein piping is of 30 m length and 216.3 mm diameter is excited by a large-scale (15m×15m) shaking table. Frequency response function and the loading-response relationship in the form of a hysteresis loop under several excitation levels are obtained. The energy dissipated by friction and collision is evaluated, and the response reduction effect due to friction and collision is quantized and evaluated in terms of "response reduction factor" and linearized damping ratio. Numerical analysis using a FEM model is also performed. Calculated of maximum displacement responses of piping are compared with those from the vibration test.
