Abstract

Based on the continuous contact force model, the rigid-flexible coupling impact dynamics of a radial rotating flexible beam is investigated. The transversal deformation and nonlinear coupled deformation, which means the longitudinal shortening caused by transversal deformation, is considered. According to the rigid-flexible coupling dynamic theory of flexible multibody system, the continuous dynamic equations of the system are established by using the recursive Lagrange method. The impact force is calculated by a nonlinear spring-damper model based on Hertz contact theory and nonlinear damping theory. By introducing the concept of impact potential energy, the system's rigid-flexible coupling impact dynamic equations are obtained. An impact dynamic simulation example is given to validate the impact model and the dynamic method, and the dynamic responses such as the impact force, the angular velocity and the flexible deformation in the whole procedure are got. The large overall motion, the small deformation motion and the impact effect are coupled.
