The animate simulation for the coaxial collision of two elastic bars is performed onthe basis of the analyses for the stress waves.
在应力波分析的基础上，对两根弹性杆纵向共轴撞击过程进行了动画模拟。

The analysis result indicated that the collision function changed the structure earthquake response condition, produces to the structure stress affects greatly.
分析结果表明，碰撞作用改变了结构的地震响应状态，对结构的受力产生较大影响。

During simulation process, the program choose suitable numerical method: mid-point interpolation or Eulor, so the loose body moves sequent, according to collision, velocity and stress.
