摘　　要：基于虚拟样机技术,考虑齿轮啮合过程中摩擦力对接触碰撞力的影响,用ADAMS软件建立渐开线齿轮啮合的动力学模型,通过仿真分析得到与理论计算基本吻合的仿真结果,并对啮合过程中轮齿间摩擦力、摩擦因数、相对滑动速度的变化及相互关系进行研究。结果表明:运用虚拟样机技术可以实现对渐开线齿轮啮合的摩擦动力学研究,从而为进一步研究齿轮啮合摩擦学特性奠定基础,具有良好的工程应用前景。Based on virtual prototyping technology, and considering the influence of friction on impact load in the process of gear meshing, the dynamic model of involute gear meshing was established by ADAMS. The simulation analysis was realized. The results of simulation analysis are basically in conformity with that of the theoretic calculation. The varia- tion trend and reaction of friction force, friction coefficient and relative sliding speed between gear teeth were researched. The results show that the research on friction dynamics of involute gear meshing can be resolved by virtual prototyping technology, which can lay the foundation for deeply studying the tribological properties of gear meshing. The method has good prospects in practical engineering application.
