Abstract
An improved contact collision model for the impact analysis of a slider–crank mechanism with revolute clearance joints is presented and discussed in this paper. Clearances in revolute joints are inevitable due to wear, machining tolerance, and local deformations. In view of the energy loss and the stiffness changes during collision, which modifies the coulomb friction force, an improved contact collision force model is established. The influence of clearance size, speed, and friction on the acceleration of slider is analyzed, and the simulation results are compared with the experimental data. The results demonstrate that the parameters of clearance joints have obvious effects on dynamic characteristics, and the improved model can accurately describe the dynamic characteristics of joints with clearance.
