混合动力汽车传动系与传统汽车的传动系相比在扭转振动特性上表现出新的特点,本文中采用集中质量参数法在AMEsim中建立了转矩耦合式混合动力传动系的扭振分析模型,计算了传动系的扭振固有特性,对其主要各阶扭振模态进行了分析。基于混合动力电机控制系统引入的PI控制参数和扭振分析模型,研究了PI控制的增益参数对传动系固有特性的影响。结果表明,比例控制参数会改变系统模态阻尼比,而积分控制参数则影响传动系的刚体模态,导致低阶的扭转频率和模态振型发生改变。

The powertrain of hybrid electric vehicle ( HEV ) exhibits new features in torsional vibration characteristics, compared with that of conventional vehicles. In this paper, lumped mass parameter method is adopt-ed to set up a torsional vibration analysis model with AMEsim for the powertrain of a torque-coupling type HEV, and the natural characteristics of powertrain torsional vibration are calculated with its modes of main orders analyzed. Based on PI control parameters introduced in motor control system of HEV and torsional vibration analysis model, the effects of gain parameters of PI control on the natural characteristics of powertrain are studied. The results show that the variation of proportional parameter may change the modal damping ratio while integral parameter may affect the rigid body modes of powertrain, leading to the changes in low-order frequencies and mode shapes of torsional vi-bration.
