摘要
本文运用三维设计软件和虚拟样机技术仿真软件得出机构间碰撞时的运动参数,再进行有限元建模,将多体系统动力学和接触碰撞的显式有限元计算相结合,得出碰撞时的应力,为多体系统中发生接触碰撞而进行应力分析提供一套仿真方法和参考依据。
In this paper,the use of three-dimensional design software and virtual prototyping simulation software for motion parameters in the collision are described,and finite element modeling multi-body system dynamics about contact-impact with explicit finite element calculation of the combination is for collision stress,in the purpose of the multi-body system in place to conduct stress analysis of contact-impact simulation methods and provide a reference.
