传统动力总成悬置参数匹配方法是将动力总成视为单刚体，对轴向较长的混合动力总成，因该方法忽略了其轴向弯曲模态的影响，易造成动力总成轴向振动过大。本文提出将混合动力总成系统分为两个刚体考虑的方法，通过选配合适的悬置刚度参数和试验验证，取得了将轴向振动加速度最大值从22．5g下降到16．4g、振动较大点数量大幅减少的效果，有重要的理论意义和实用价值。

The powertrain is regarded as a single rigid body for matching parameter in traditional method. However, for long-axial hybrid powertrain, the traditional way ignored the axial bending-mode, which makes serious axi- al-vibration. In this paper, a new method has been adopted which regards the powertrain as two rigid blocks so as to make the maximum value of axial vibration from 22.5 g to 16.4 g, and the number of points of vibration peak de-creased largely with the method validated. There is great theoretical significance and practical value.
