摘要
本文首先建立了一种FR式汽车动力传动系扭振的多自由度分析模型,据此对其扭振固有特性进行了较详细的计算分析。然后对适用于动力传动系扭振噪声控制的各种可能的结构修改(即扭转刚度、转动惯量和扭振阻尼)措施分别进行了模拟计算分析。这些分析结果对于FR式汽车具有典型意义。
A multidegrees-of-freedom analysis model is set up of torsional vibration of an automotive power train of FR type. Based on the model, the natural vibration characteristics are analysed in detail. A number of possible and practical ways of structural modifications (including that of the torsional stiffness, mass and damping) for controling the vibration and noise are simulated. The results obtained are of typical significance for FR automobiles.
