Abstract:A common issue associated with gas bearings is the tendency to generate self-excited vibrations, leading to instability. In this paper, the fluid-structure coupling dynamic model of aerostatic bearing-rotor system is established to address this problem, and a hybrid method including the finite difference method and direct integration method are employed to simultaneously solve the transient Reynolds equation and rotor dynamic equation. Furthermore, based on the orbit of rotor center, frequency spectrum diagram… Show more
