基于Adams与RecurDyn的机械结构Hertz接触仿真对比分析

摘要

Contact simulation is one of the important parts of the dynamic simulation software which can simulate the motion state and stress of the mechanical system more and more. In order to get the difference of the multi-body dy-namics simulation software Adams and RecurDyn simulation of the Hertz contact problem, comparing the two kinds of contact simulation algorithm is compared,using Creo2.0 the virtual prototype of the three classical institutions is estab-lished. The three kinds of mechanism of Hertz’s contact problem is respectively using Adams and RecurDyn simula-tion,state of motion and contact force curve was obtained and compared with the simulation results. The simulation re-sults provide a reference to the Hertz contact problem analysis.%接触仿真是让多体动力学仿真软件能够更加真实的模拟机械系统的运动状态和受力情况的重要环节之一。为了得到多体动力学仿真软件Adams和RecurDyn在进行机械结构的Hertz接触问题仿真时的区别，对比了两种软件接触仿真的算法，运用Creo2.0建立了两种经典机构的虚拟样机，并针对某型越障小车的定轴轮系进行数字化建模，对这三种机构的Hertz接触问题分别运用Adams和RecurDyn进行了仿真，得到了运动状态曲线和接触力曲线，对比了仿真结果。仿真结果给进行Hertz接触问题分析的学者提供了参考。
