摘要/Abstract

摘要： 搭建某实车动力传动系统的当量模型，建立发动机转矩激励模型，并以转速和谐次计算获得主谐次频率作为外部激励转矩的主导频率。随后对系统进行受迫振动分析，获得振动响应恶化频带，将模型简化，进行固有振动特性分析，探究振动恶化原因。然后根据系统固有振动特性匹配扭转隔振器和吸振器减振性能参数，将两种装置与动力传动系统整合，进行仿真计算，对比两种装置减振效果，并从减振机理分析两者差异性。最后将扭转隔振器和吸振器组合成减振组块安装到系统中，进行参数匹配和结构设计，制定频率调谐控制方案，利用仿真计算验证其优良的减振性能。

Abstract: The equivalent model of a real vehicle powertrain system is built, and the engine torque excitation model is established. The main harmonic frequency is calculated by the engine speed and harmonic order as the dominant frequency of the external excitation torque. Then the forced vibration analysis of the system is carried out to obtain the deterioration frequency band of the vibration response, the equivalent model is simplified, the natural vibration characteristics are analyzed to explore the causes of the vibration deterioration. According to the natural vibration characteristics, the torsional vibration isolator and the vibration absorber performance parameters are matched, and these two devices are integrated into the powertrain system for simulation calculation. The vibration reduction effects of the two devices are compared, and the difference between the two devices is analyzed from the mechanism of vibration reduction. Finally, the torsional vibration isolator and the vibration absorber are combined into a vibration damping module, the performance parameters are matched, the structure is designed and the frequency tuning control scheme is formulated. The simulation results verify the excellent vibration reduction performance of the damping module.

Key words: powertrain system, dominant frequency, torsional vibration isolator, vibration absorber, vibration damping module
