摘要
基于显示动力学和接触碰撞分析的基本理论,采用有限元方法建立冲击试验机的碰撞模型,对接触面的冲击载荷进行仿真分析。根据仿真结果得出冲击试验中各碰撞部件的运动与受力状况,以及冲击力对碰撞速度等参数的变化规律,为后续的接触面状态测试奠定基础。
Based on the fundamental theories of explicit dynamics and contact impact analysis, a finite element model of an impact test machine was established to analyze the contact force of the impact test machine. The contact forces under different initial velocity conditions were acquired by numerical simulation. The motion and stress distribution of all parts were obtained as well, which forms a base for further force measurement On the contact surface.
