双行星排式动力耦合机构动态特性分析
Dynamic Characteristic Analysis of Double Planetary Gear Power Coupling Mechanism
摘要
Abstract
Taking a double planetary gear power coupling mechanism of hybrid electric vehicle as an example,this paper established multi-body system dynamics model of the double planetary gear power coupling mechanism through the comprehensive application of UG,ADAMS and ANSYS.Then,simulation analysis of multi-body system dynamics model under typical steady conditions was carried out.Through the analysis of time domain and frequency domain response curve of shafting angular acceleration and meshing forces,this paper obtained the dynamic characteristics of coupling mechanism in the steady state conditions (such as electric,cruise) and non-steady state conditions (such as engine starting).Simulation results show that in the steady state conditions,the peak frequency of dynamic characteristics is rotating frequency,meshing frequency of double row of gear planetary and its octave.Transient impact exists in the initial stage of non-steady state,but the dynamic characteristics of front row planetary gear have little influence on rear planet gear.关键词
