以2种不同支承形式的中介轴承双转子结构系统为研究对象,建立了对转双转子系统轴向-径向耦合碰摩有限元动力学模型。基于陀螺效应引起轮盘偏转产生轴向位移,导致轴向碰摩的假设,给出了轴向碰摩力与节点坐标之间的表达式,考虑了不同支承形式的中介轴承耦合力处理方式,并以此为基础详细推导了系统的振动微分方程。模型既能描述转静间的轴向碰摩和径向碰摩,又允许轴向碰摩和径向碰摩独立发生,亦可共同发生。

A new axial-radial coupling rubbing dynamincs model of the counter-rotating dual-rotor system is built with the study object of the dual-rotor system with two different inte-shaft bearings. Based on the assumption that the gyroscop-ic effect causes disk deflection which produces axial displacement and leads to axial rubbing, the expression between axial rubbing force and node coordinates could be given. According to the two different intermediary bearing forms, distinct treatment of bearing coupling force is considered. And vibration differential equation of the system is deduced in detail. The model can be used to describe the axial rubbing and radial rubbing between the stator and the rotor, and the axial rub-bing and radial rubbing can occur independently or dependently.
