| 摘 要： | 首先研究两弹性体碰撞振动中的接触力，用多项式逼近具有分数指数的Ｈｅｒｔｚ模型来实现近似解析分析，然后讨论与碰撞有关的各因素对两柔性梁受迫碰撞振动的影响。当耦合模态解增加时，碰撞强度增大，系统呈现典型的非线性

| Abstract: | From the Hertz contact law, the contact force between two vibro impacting beams is modeled and approximated through the use of a polynomial. Then, the effects of various parameters on harmonically forced vibro impacts of two flexible beams are analyzed. It is found that the impact strength and nonlinearity of the system greatly depend on the number of the coupled normal modes. |
