The physical characteristics of a human finger are important in the work by hand. Therefore, the physical and numerical modeling of fingertip is useful for the design of various equipments, for example, a handrail of stairs, a robot hand, an operation simulator, and so on. In this study, "Coulomb friction", "absorption by fingerprint and sweat" and "elasticity of finger" are considered as the element of the friction characteristics. The aim of this study is to express the force by these characteristics as function model and to make the physical fingertip model. At first, the force by friction and absorption are measured, and the contact area between fingertip and board is calculated. Next, the function of friction force with respect to vertical force acting on the contact surface between fingertip and board is suggested. Finally, the actual finger model is made and the friction force is modeled to the function.

A number of different structures in industrial facilities are installed on supports. There is the case that the damage occurs by the coupled vibration. The response magnification is obtained from the modal natural frequency and the modal damping ratio of the coupled system in the seismic design. Therefore, the modal natural frequency and the modal damping ratio of the coupled system are required. The natural frequency and the damping ratio of the support and the structure are obtained during the initial design process or by a shaking test. However, the modal natural frequency and the modal damping ratio of the coupled system are not easily obtained. The modal natural frequency of the coupled system can be calculated from theoretical equation, but the modal damping ratio cannot be easily calculated. In the present study, an equation to calculate the modal damping ratio of the coupled system with classic damping is presented. In addition, a simple equation to calculate the modal damping ratio with a non-classic damping system is proposed. This equation is evaluated both theoretically and experimentally. The proposed equation is useful for obtaining the modal damping ratio without performing eigenvalue analysis or a shaking test.

In the case of lure fishing, casting is the element which anglers must master in order to cast a lure at an appropriate position. Lure fishing constitutes various elements, for example, casting, reeling, hooking and landing, but the importance that casting holds is extremely large. This study uses experimental and computational analyses to investigate the dynamic behavior of lure casting. The casting process and the timing of the lure released are important for the proper presentation of lure. Moreover, the shape of a rod before the lure released is important for a long cast or controlled cast. However, it is difficult to grasp the phenomenon or to make a numerical model. Therefore, the most suitable casting method will be clarified from the viewpoint of sports engineering and human dynamics. In this paper, the system of rod and lure is modeled, and the behavior of the rod and the flying distance of a lure are calculated. Especially, influence of lure weight is clarified.

This paper deals with the response reduction effect by gap. Gap is expected to decrease the relative displacement by guide. The relative displacement between structure and support becomes larger at long period in the case of linear system. Therefore, the response reduction effect by gap 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 collision. Therefore, the response reduction effect by gap is evaluated from the viewpoint of energy. The ratio between kinetic energy and input energy is utilized. In this paper, "Response Reduction Map" based on energy for long period gap system is suggested. This map shows the range that energy response ratio is less than the ratio of linear system. The response reduction map without complex non-linear time history calculation can easily obtain the proper parameters, such as natural period or gap size. 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 from the design spectrum is shown.

In this paper, the system of rod and lure is modeled, and the behavior of the rod and the flying distance of a lure are calculated in the case that line tension is considered. The difference of the behavior and flying distance with line tension is investigated. And suitable timing that angler releases the line is clarified. Moreover, hang length of lure is investigated and proper length is obtained.

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.

This study uses experimental and computational analysis to investigate the dynamic behavior of a fly line. Fly-casting is one of the most significant issues in fly-fishing. In order to cast a lightweight fly, the weight of a fly line is utilized. Fling speed, the casting process and the loop shape of the line while in flight are important for the proper presentation of flies. Moreover, the shape of a fly line is also important for a long cast or controlled cast. The rebound phenomenon occurs in the casting process. In this paper, the effect of rebound is investigated experimentally.

This report deals with the fundamental behavior of friction dampers for piping systems installed in industrial facilities. Energy dissipating effect depends on sliding displacement and friction force. If the sliding motion increases, the effect of energy dissipation is expected to rise. In this report, a ball screw-type magnetic friction damper is proposed to adapt on piping systems. In order to increase the frictional sliding, this damper converts an axial motion to a rotating motion by a ball screw. Frictional behavior occurs between a rotation disk and a fixed disk on the frame of damper Friction force depends on the permanent magnets located on the fixed disk. The fundamental characteristics such as load-displacement curves, damping force at the ball bearing and inertia force of the rotation disk are obtained by experiments and a calculation model is made from the experimental data. The calculated responses are, then, compared with the results from the experiment. The calculation model is applied to a one-degree-of-freedom-system in order to investigate the response reduction effect of the system. An electromagnet is applied on the damper instead of the permanent. magnet to control friction force and the controlled behavior is evaluated.

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.

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.

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 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.

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.

This report deals with the experimental study of seismic response behavior of piping systems in industrial facilities such as petrochemical, oil refinery, and nuclear plants. Special attention is focused on the nonlinear dynamic response of piping systems due to frictional vibration appearing in piping and supporting devices. A three-dimensional mock-up piping and supporting structure model wherein piping is of 30-m length and 200-mm diameter is excited by a large-scale (15 m X 15 m) shaking table belonging to the National Research Institute for Earth Science and Disaster Prevention in Tsukuba, Ibaraki. Power spectra of the response vibration and the loading response relationship in the form of a hysteresis loop under several loading conditions are obtained. The response reduction effect caused by frictional vibration is evaluated and demonstrated in terms of ''response reduction factor.''
