The Kinematics Simulation Study of Machine-Hydraulic Continuous Transmission Based on UG and Adams

本文分析了机液复合传动的基本原理。建立了基于UG对无级传动变速器的三维模型,在此基础上运用Adams对模型进行运动学仿真,同时介绍了在Adams仿真过程中差动轮系约束的建立方法以及还存在的缺点,并且提出了建立齿轮约束的新的可行的方法。在建模和仿真过程中对液压部分进行了简化,从而简化了三位模型和运动学分析。最后对仿真结果和理论结果进行了比较分析。结果表明基于UG和Adams机液复合无级传动变速器运动学的仿真分析方案是可行的。

This paper analyzes the basic principles of Machine-Hydraulic Continuous Transmission.Three-dimensional model of Continuous Transmission was established which based on UG.On this basis,kinematics simulation of the model was used by Adams.Meanwhile,this paper also introduced the way of constraint of Differential gear and Shortcomings in the course of Adams simulation,and proposed a new and feasible way of establishment of gear constraint.The hydraulic parts was simplified in the process of modeling and simulation,which simplified the three-dimensional model and analysis of dynamics.Finally,compared and analyzed the simulation results and theoretical results.The results show that this program is feasible.
