Comparative Study on Rigid-Flexible Model of Oblique Impact between Cylinder and Ground

Abstract:

The oblique impact between cylinder and ground with friction is studied. The applicability and limitation of the classical impact theory of rigid body are verified by building oblique impact between cylinder and ground of flexible model and rigid model respectively. The finite element method is used to build the flexible model of oblique impact between cylinder and ground. It is analyzed that the sliding mode of the contact point, the direction of the friction force and Newton coefficient of restitution during collision varying with different tangential velocity. Comparing the result with the classical impact rigid model, it is proved that numerous sliding modes are existent during collision. Additionally, the applicability of the rigid model is proved in unidirectional sliding mode.
