| 摘 要： | 车辆动力传动系统的扭转振动(简称扭振)表现对于车辆舒适性有极大的影响,为了解决某前置后驱车辆传动系统的扭振控制,结合机械动力学知识通过LMS AMEsim软件建立车辆传动系统模型,与实测数据进行比较以验证模型的可靠性。通过扭振频率与模态分析,确认发动机与传动系统在35.2334 Hz下有共振发生,通过优化离合器参数可使扭振得到很好的控制,同时也提出通过多目标遗传算法对传动系统多参数进行优化,更好地提高传动系统的扭振表现。

| Abstract: | Torsional vibration performance of vehicle power driveline system has great influence on vehicle comfort.In order to solve the torsional vibration control of rear wheel drive vehicle driveline system,a vehicle driveline system model is established by LMS AMEsim software combined with mechanical dynamics knowledge.Compared with the measured data to verify the reliability of the model.Through the frequency and modal analysis of torsional vibration,it is confirmed that there is resonance between engine and driveline system under 35.2334 Hz,and the torsional vibration can be well controlled by optimizing clutch parameters.At the same time,the multi-objective genetic algorithm is proposed to optimize the multi-parameters of the driveline system to improve the torsional vibration performance of the driveline system. |
