The crankshafts shown in Fig 1-4 is actually made up of various parts such as main bearing journals, rod journal, crank arm, bearing, counter balanced weight and flywheel end.

在图1-4中，曲轴实际上由以下不同的部分组成，它们分别是：主轴承轴颈、连杆轴颈、曲轴臂、轴承、平衡配量（？）以及飞轮端。

With reference to a symmetrical unbalanced rotor treated as a continuous elastic shaft suPPorted at its end by lubricated journal bearings, the short bearing model is adoPted.

研究了非线性弹性转子-轴承系统的轴心轨迹，认为对称不平衡转子是连续弹性轴，它两端支撑在滑动轴承上，油膜反力采用非线性短轴承模型。
