Abstract

Impact is universal phenomenon in mechanical system with clearance. In order to accurately describe the effect of impact between journal and bearing in clearance joint, an improved contact force model is presented in this work, which assumes the coefficient of restitution during impact is varied, and sets up the modeling of restitution coefficient related to initial impact velocity and yield strength of material. Then the improved contact force model is validated based on a great number of numerical simulations and a typical pendulum experimental test rig, the numerical results are in reasonable agreement with those experimental results, furthermore, the relative errors are all no more than 10% between numerical and experimental results. It can be concluded that the improved contact force model is effective, and can exactly describe the impact effects between two bodies in mechanical system.
