为了分析混合动力汽车双模式多级齿轮动力传动机构扭转振动产生的原因及其影响因素,基于SIMPACK建立了整车动力学模型。通过对动力学模型施加激励和设置输出通道,构建了扭振仿真系统。应用扭振仿真系统分析了多级齿轮传动机构的振型,并与理论计算和实验结果进行了对比验证。扭振仿真系统振型分析的结果与理论计算的传动系统固有频率以及噪声实验获得的主噪声频率一致,证明了构建系统的正确性。在此基础上,分析了阻尼减振器的阻尼、刚度的变化等目标优化参数对多级齿轮传动机构产生的扭转振动的影响。结果表明,将扭转减振器参数调整在适当范围内,对多级齿轮传动机构部分阶次的扭转振动有较好的衰减作用。
In order to analyze the cause and influence factors of the torsional vibration of the dual mode multistage gear transmission, a hybrid electric vehicle dynamic model is established based on SIMPACK. By means of imposed excitation on the dynamics model and set output channel on it, a simulation system for torsional vibration is constructed. The vibration mode of transmission is analyzed as a torsional vibration simulation system, and is validated by the results of theoretical calculation and experimentation, which verified the effectiveness of the established simulation system. On this basis, some objective parameters, such as stiffness and damping of torsional damper, are analyzed for the effect of dampen vibration. The result shows that it has a good effect on the attenuation of torsional vibration in certain frequency through adjustments to characteristic parameters of torsional damper in a proper range.
