该文研究了带挤压油膜阻尼器的转子－支承系统的稳态动力响应，提出了求解非线性转子系统稳态动力响应的三角级数法。通过对某涡喷发动机转子－支承系统模拟实验台的计算、分析及实验研究，证明该文给出的方法正确、合理。
In this paper, the steady-state dynamic response of the rotor-support system with squeeze film damper is studied. A triangular series method is proposed to solve the steady-state dynamic response of the nonlinear rotor system. Through the calculation, analysis and experimental research on the simulation test rig of a turbo -jet engine rotor-bearing system, the method given in this paper is proved to be correct and reasonable.
