摘　　要：以N485柴油机轴系为例，建立了“集总参数”和“有限元”两种扭振力学模型，并分利用霍尔茨法、有限元法、迁移子结构法计算了该轴系的扭转自由振动，通过与实验结果进行比较，分析了两种模型、三种计算方法的特点。Taking N485 diesel engine as an example, two models of engine shaft system are established and the torsional vibration is calculated respectively with Holzer method. finite element method and sub-structure method. By comparing the experiment results the characteristics of the two models and the three calculating methods were analysed.
