摘要：
In this chapter, the influence of cross-coupling effects on the rubbing related dynamics of rotor/stator systems is investigated. The model considered in this chapter is a four-dof rotor/stator system, which takes into account the dynamics of the stator and the deformation on the contact surface as well as the cross-coupling effects. The stability of the synchronous full annular rub solution of the model is first analyzed. Then, the cross-coupling effects on the stability of the system at different system parameter planes are studied. It is found that the cross-coupling damping of the stator benefits the synchronous full annular rubs and that of the rotor has a little influence on the response. While the cross-coupling stiffness of the stator always reduces the stability domain of the response, the cross-coupling stiffness of the rotor may either increase or decrease the stability domain depending upon its value.
