行星轮转动惯量对换挡过程动态特性的影响

该文简述了传动系统在任意结合工况下的运动学方程、运动微分方程和力矩平衡方程的推导思路.通过求解这三个方程建立了传动系统的动态模型,得出传动系统所有构件在任意瞬时的转速、加速度和所受的力矩.运用该模型对某行星变速箱进行换挡仿真计算,从仿真结果分析评估了行星轮构件转动惯量对行星变速箱换挡过程动态特性的影响.

The Effect of the Moment of Inertia of Planetary Gears on the Dynamical Properties by Shifting Process

This paper gives a brief review on how to build the kinematical equations,the kinematical differential equations and the motion balance equations.With these three equation groups,the angular velocity,acceleration and torsional moment of all members at any time can be calculated.A practical planetary gear-box was taken as an example to show this simulation process.The results show that the moment of inertia of planetary gears has little effect on the dynamical properties by shifting process.
