摘要/Abstract

摘要： 针对混合动力扭振分析复杂化的特性，以某P2构型的混合动力运动型实用汽车(SUV)为研究对象，建立传动系统集中质量模型，分析其固有特性和激振响应特性.然后基于AMESim仿真软件对传动系统进行扭振影响因素分析，对离合器刚度、阻尼等主要参数进行灵敏性分析，探讨其对扭振的影响特点.仿真结果表明，改变离合器减振刚度可以影响传动系统固有特性，进而改变其共振峰值及频率；增大离合器阻尼有利于降低传动系统衰减共振的峰值，但是不利于高速时的减振.

关键词: 混合动力, 传动系扭振, 集中质量, 固有特性分析, 灵敏性分析

Abstract: For the complex characteristics of the torsional vibration analysis of hybrid vehicle， a P2 hybrid SUV(sport utility vehicle) was taken as a research object， and the transmission system concentrated mass model was established to analyze the inherent characteristics and excitation response characteristics. Then， based on AMESim simulation software， the influence factors of torsional vibration of transmission system were analyzed， and the sensitivity of main parameters such as clutch stiffness and damping was studied. The influence characteristics of torsional vibration are discussed in detail. The simulation results indicated that changing the damping stiffness of the clutch will affect the inherent characteristics of the transmission system and change the resonance peak value and frequency; increasing the damping of the clutch will reduce the peak value of the attenuation resonance of the transmission system， but was not good for vibration elimination at high speed.

Key words: hybrid power, drive train torsional vibration, concentrated mass, inherent characteristic analysis, sensitivity analysis
