摘　　要：通过对行星啮合式无级变速系统在UG及ADAMS中进行联合建模(几何建模和约束建模),建立了一种基于接触力的虚拟样机仿真模型,通过选取合理的接触力参数,获得了该系统的动力学特性曲线。通过虚拟样机试验研究证明了该系统具有过零无级调速的可行性,验证了其调速范围优于环锥行星无级变速传动系统,研究结果对该系统的深入设计研究有预判和指导作用,且具有一定的应用价值。A virtual prototyping simulation model is established based on contact force through the joint modeling（geometric modeling and constraint modeling） of planetary mesh-type CVT system in UG and ADAMS.By selecting appropriate contact force parameters,the dynamical characteristic curves are obtained.The experimental study on the virtual prototyping shows that the system has the feasibility of over-zero variable speed.It is verified that the speed range of this system is larger than planetary cone ring continuously variable transmission system.The results of this study is very useful in further studies of this issue.
