Abstract

In this paper, the contact force between impacting bodies is modeled by using Hertz force displacement law and linear or nonlinear damping function. For the exact impact analysis, the dynamics of the sensor attached to the impacting body is considered. In order to verify the appropriateness of the proposed contact force model, the drop type impact test is carried out. Through numerical analysis and experiment, the influence of sensor dynamics and the characteristics of contact force model are investigated.
