Torsional Vibration Analysis and Influencing Factors of Power Split Hybrid Transmission System
摘要
Abstract
For a hybrid electric vehicle,considering the engine,motor,composite planetary gear mechanism,clutch,reducer,differential and half shaft,the dynamic model of power split transmission system is established with the centralized mass method.On this basis,the natural frequency and vibration mode of the transmission system under different operating conditions are analyzed,the relationship between the excitation frequency of motor,engine and the natural frequency of the transmission system is studied respectively,and the influence law of torsional damper stiffness on the natural frequency of the transmission system is simulated and analyzed.Finally,by changing the stiffness of the torsional shock absorber,the resonant speed of the transmission system is adjusted far away from the common working area of the engine.关键词
