Research on the contact collision force model of the cam system

A convenient and effective modeling method for contact collision force was explored to address the difficulties in modeling and simulation verification of cam pairs. Taking the L-N contact collision force model into consideration, based on the modified hybrid contact collision force model of Bai, a contact collision force model for the Roller-Cam system is established, and it can be used to solve the collision force and collision deformation. Finally, the influence of the initial collision speed and the radius of curvature for the impact point on the collision force and deformation is calculated respectively, which points out that the initial collision speed and the curvature radius of the cam affect the dynamic response of the collision process, furthermore, the initial velocity of collision has a more obvious impact on the collision force and collision deformation of the system.
