中文摘要	以某型混合动力公交车传动系为对象,应用AMESim建立系统扭转振动仿真模型,并进行扭振响应计算与分析。根据公交车运行特点构造了一个包含起动、低速和高速运行以及停机过程的完整工作循环,计算得到了系统在该工作循环中的扭振响应,据此分析了典型结构参数或工况参数对扭转振动响应的影响。仿真结果表明,减振器的刚度和阻尼、离合器接合时压盘与从动盘的转速差都会直接影响传动系扭振响应。适当降低ISG电机起动力矩、限制传动系急加速和急减速阶段的加速度都能有效减低传动系扭振水平。; A dynamic simulation model was established using AMESim for investigating the torsional vibration in the drive line of a series-parallel hybrid electric city transit bus. The torsional vibration analysis was conducted to understand the influence of main factors. Based on typical city bus operating characteristics, operating procedures were constructed, in which the hybrid powertrain experienced vehicle launching, low-speed running, engine start, high-speed running and regenerating braking. Simulations were performed to understand the influence of key component design parameters or a dynamic duty cycle. Simulation results show that the torsional vibration responses are closely related to spring stiffness and damping coefficient of the input damper and clutch damper, as well as the degree of speed synchronization upon clutch engagement. The results also reveal that the torsional vibration of a drive line is effectively reduced by reducing the ISG motor torque for starting the engine, and by limiting the acceleration of the hybrid powertrain when a rapid acceleration or a deceleration happens.
