摘　　要：由于轻卡动力总成的振动形态复杂,结构薄弱部位容易被激励而引起共振现象。为了解动力总成动态特性,采用有限元方法和PolyMAX方法分别对轻卡动力总成进行试验模态分析。通过两者结果对比分析,有效地反映轻卡动力总成的动态特性,验证了两者分析的可靠性和合理性,为动力总成故障诊断及动力学优化设计提供理论依据。Due to the complexity of light truck powertrain vibration shape,the structure weak parts is easy to motivate and cause resonance phenomenon.In order to obtain the powertrain dynamic characteristics,by using the finite element method and PolyMAX method,simulation and experiment modal analysis for light truck powertrain are respectively carried out.By analyzing and comparing the results of both,the dynamic characteristic of the light truck powertrain is effectively reflected,the reliability and rationality are proved.The theory basis for the fault diagnosis and dynamic optimization design of the light truck powertrain are provided.
