| Research Abstract |
We aimed to investigate the relations between the physical, psychological and physiological reactions of the human body exposed to external vibrations and to construct a synthetic vibration model of the human body ; the model should reproduce not only the physical behavior but also its psychological and physiological behavior. Numerical models formalized according to Lagrange's equation, the finite element method, etc. were employed. The experiment was implemented under condition in which the human is exposed to external vibration which perpendicularly vibrates at any frequencies. As a result, it was clear that there are resonance points showing remarkable shaking of the head, the chest and the abdomen in the frequency range 2 to 11 Hz. Further, it was suggested that the relations may be expressed in terms of multiple regression analysis. Moreover, a simple vibration model of a person riding in an automobile was numerically constructed to reproduce the physical reactions of the human, and the psychological and physiological reactions were predicted. Finally, looking to the future view, we referred to the possibility of expanding the vibration model into a more generally applicable vibration model using the finite element method with a view to applying the vibration model to handicapped people.
Furthermore, a possibility for the automotive industry, train-building industry and the field of industrial design at large, specifically in the area of comfort, was discussed through experimental and numerical investigation into the vibration characteristics of people riding in automobiles with a human vibration numerical model.
