Research Abstract

The shock absorbing mechanism of human body to minimize the vertical acceleration during jumping down to a hard surface was investigated. The dynamic model of human lower limb was built with a link joint. The muscle model was consisted of a contractile element, a series elastic element and a viscous element, and the experimental and theoretical investigations were carried out. The results showed that the shock could be absorbed passively by deep bending, and it could be absorbed more actively by bending motion of knees.
As an example of coupled motion of a human body and a tool, the forces and moment in the wrist and the elbow caused by striking tennis ball were theoretically investigated. The dynamic model of a ball, a racket and an arm were formulated, and the modes of vibration and impulse response were calculated. The forces can be decreased by designing the racket such that the striking point becomes the nodal point or the natural frequency of the ball and racket coincides each other.
The dynamic analysis of the natural teeth and endosseous implant were also carried out, and stress distribution around teeth and bone were investigated in order to find the optimum medical treatment.
