20213 Biomechanical analysis for transient body behavior of the vehicle occupant

Abstract

For comfortable vehicle design, understanding the body behavior of the occupant is important. The purpose of this study was to quantify the motion response of the body to transient lateral acceleration input. In this experiment, lateral acceleration was simulated by adding the acceleration to the carriage with a fixed vehicle seat by the tension of the rubber. The body behavior at that time was measured by the force plate and motion capture system. It was confirmed that the roll angle of the head showed a large response the most, yaw angle rotation was also seen by the posture change.
