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。

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.

此法缺点是焊接后链条箱易变形、两端轴的同轴度超差以及支撑强度不够。

The shortcomings of this method is easy to welding deformation of the chain of boxes, at both ends of the coaxial shaft tolerance and lack of support strength.
