次碰撞的研究现状及存在的问题

Research status and existing problems of the collision

为了对次碰撞现象进行实验研究,主要利用有限元分析软件ANSYS/LS-DYNA,进行了撞击实验的动力学仿真,系统的研究了金属球撞击初速度和撞击位置两个因素对次碰撞动力学响应的影响。

To experiment is carried out to study the collision phenomenon,mainly using finite element analysis software ANSYS/LS-DYNA,the impact experiment of dynamic simulation,the system studied metal ball initial impact velocity,impact position of the two factors on the influence of collision dynamics response.
