Impact response analysis including biological reactions for visual information when a moving levitating block collides with palms of hands

Abstract

This paper describes dynamic responses of alive human palms to receive moving objects with / without visual information. We measured transient responses when a levitating block collided with the palms. The impact force is measured using Levitation Mass Method (LMM) proposed by Fuji. Then, experimental results were simulated by numerical analysis using FEM. To reproduce behaviors of palms of living bodies, they are modeled using nonlinear complex restoring force element. This nonlinear complex element including positive / negative nonlinear hysteresis is attached to the block modeled with solid finite elements. The experimental data were compared with calculated ones.
