摘要
对引起轻度混合动力电动汽车(MHEV)动力系统轴系振动的电磁因素进行了分析,揭示了机械和电磁两方面相互耦合作用对振动的影响规律。电机转子的电磁转矩、扭转刚度和阻尼的作用将改变原发动机系统轴系的动态特性。对电机助推和发电2种不同模式下系统轴系振动特性进行了理论仿真和实验的定性研究,两者结果体现了较好的一致性。
Based on analysis of characteristic parameters of a motor, the research of hybrid systematic vibration under electro-mechanical coupling was completely proceeded. Dynamics characteristic of the engine shaft system will be changed by electromagnetic torque, torsion rigid and damp of motor. A qualitative analysis on the characteristic of a hybrid system vibration was performed when the motor worked at two different kinds of modes of assistant push and power generation. The results from both are consistent with each other.
