摘要
The vibration of the axially moving beam impacted by moving and rotation load is a type of complicated non-linear problem. In this paper, the vibration model and differential equation of this problem are built. A kind of modal shape function considering changing of the beam's length is provided. The equation is dispersed using Galerkin method and solved by the method of Newmark-beta. The factors influencing the vibration are analyzed. The simulated results show that the model and method is reasonable.
