在偏心载荷条件下测试了由刚性安装的转子和柔性安装的定子组成的面密封模型。观察到定子进动和章动组合形式的自激振荡。运动的性质及其频率取决于转速、密封间隙和外部倾斜力矩。一些无法解释的密封失效和密封面波纹可能是这种自激摆动的结果。
A face seal model consisting of a rigidly mounted rotor and a flexibly mounted stator was tested under conditions of eccentric loading. Self-excited oscillations in the form of combined precession and nutation of the stator were observed. The nature of the motion and its frequency are dependent on rotational speed, seal clearance, and external tilting moment. It is possible that some unexplained seal failures and waviness of seal faces are the result of such self excited wobble.
