大型高速回转机械的转子在动平衡机上进行高速动平衡时，滑动轴承—转子系统的工况与机组的实际运行工况具有良好的一致性。考虑到现场识别滑动轴承油膜动特性系数时存在的种种困难，本文提出一种在动平衡机上识别滑动轴承油膜动特性系数的新方法。数值试验表明，本文的方法是行之有效的。 Large high-speed rotary machinery rotor in the dynamic balancing machine for high-speed dynamic balance, the sliding bearing - rotor system conditions and the actual operating conditions of the unit has a good consistency. Considering the difficulties in locating the dynamic coefficient of the oil film of the sliding bearing, a new method to identify the dynamic coefficient of the oil film in the dynamic balancing machine is presented in this paper. Numerical experiments show that the method in this paper is effective.
