摘要
将非线性非稳态油膜力模型与密封流体Muszynska模型结合,对非线性非稳态油膜力支承下的密封-转子系统流体激励行为进行了研究,发现其响应随转速比的变化具有复杂的动力学行为,产生了包括周期、拟周期等丰富的振动现象,具有很强的非线性特征.
The model of nonlinear and unstable oil film force was combined with Muszynska mode of seal fluid and the concerned nonlinear dynamics was studied. Complex dynamical responses of airflow-induction are detected with rotary speed variation, which include periodic and quasi-periodic vibrant phenomena with strong nonlinear character.
