摘要
基于键合图理论,在考虑内外齿轮时变啮合刚度、阻尼和齿面摩擦力的基础上,使用LuGre摩擦模型,建立了NGW型行星齿轮的键合图模型,并在此模型的基础上构建了PX型和XP型单环路行星传动系统的键合图分析模型。使用20sim软件分别对XP型和PX型两种单环路行星传动系统进行了速度和效率的计算和仿真,其仿真结果表明键合图建模理论与方法可以用于解决单环路行星传动系统非线性动力学问题的分析和求解。
Based on bond graph theory, considering the time-varying meshing stiffness, damping and tooth surface friction force of internal and external gear, using LuGre friction model, the bond graph model of NGW type planetary gear was established. And then, the bond graph analysis models of the XP type and PX type single loop planetary transmission system were set up. The speed and efficiency of XP type and PX type single loop planetary transmission system was computed and simulated in 20sim software. The results show that the modeling theory and method of bond graph can be used to solve the nonlinear dynamic problems of single loop planetary transmission system.
