Research Abstract

A three-dimensional dynamic modeling of human's body is carried out at first by using the model of fourteen joints and fifteen masses system. The experiments on human body have been done for three exciting directions of the frontal, the transverse and the vertical. The equations of motion with the 45 D.O.F are formulated and the fourteen joint parameters are identified by the method of partial optimization technique with a least squares approach. In the next place, full modeling of a car body has been made by adding nonlinear 20 crash elements around car body. Combing the model with dynamic modeling of human body stated above, the dynamic responses of a vehicle-driver system are analyzed and the dynamic responses of driver have been clarified numerically with the influences of the variance of seat positions, speeds and hump conditions considered. The basic characteristics of energy absorption of crach members of a car when it collides onto a barrier in skew diresction have been strdied … More . Static and dynamic collapsing tests have been done for a series of scale models of front side members with different shapes, under the conditions of different crash angles, by using a compression machine and a weight-drop apparatus. Based on the force-displacement curves obtained by local progressive buckling and globle post bucklig, it has been clarified how the energy absorption characteristics of crash members vary with the change in colliding angle. The energy absorption characteristics of a compound structure which is assembled by the above crash members, an engine, etc., are analytically investigated, and it is verified how they vary with the colliding conditions such as colliding angles, etc.. Finally, a series of dynamic response analysis of a car, driver and driver joint-forces, have been carried out under the condition that when it collides onto another moving car by varying car mass, speeds and collision angle, and the influence of each parameter on these response have been made clear. The modeling of driver joints with musculoskeletal system have been made in the next place, and the time histories of primary muscle-forces have been calculated based on the optimisation method. The musculotendon members are modeled by contractile component, series elastic component and parallel elastic component. And it is made clear how the dynamic response of driver-joint forces and muscle responses vary with car mass, speeds and collision angle. Less
