本文通过理论计算和实验,研究了带定心弹性支承的挤压油膜阻尼器刚性转子的双稳态特性。采用阻尼器轴颈偏心率、传递率和落后相位角的变化表示这种特性。
In this paper, the bistable characteristics of a rigid rotor of a squeeze film damper with centering elastic support are studied by theoretical calculations and experiments. The use of damper journal eccentricity, transmissibility and lag phase angle changes represent this feature.
