摘要

The impact dynamics of flexible multibody systems is analyzed based on the impulse momentum method (IMM). According to the rigid-flexible coupling dynamic theory of flexible multibody system, the continuous dynamic equations of the system are established by the recursive Lagrange method. By using IMM, the impact dynamic equations of the system are obtained. The impact process is assumed to be timeless, and the generalized velocity mutates at the impact moment. The contact criterion is given. An impact dynamic simulation example for a two-link flexible multibody system is given, as well as the global dynamic behaviors. The results show that the impact dynamic solving method based on IMM can be used for the global impact dynamics of flexible multibody systems. Impact affects the dynamic behaviors of the system during and after impact. The large overall motion, the small deformation motion and the impact effect are coupled.
