Dynamic Model and Fault Feature Research of Dual-Rotor System with Bearing Pedestal Looseness
The paper presents a finite element model of dual-rotor system with pedestal looseness stemming from loosened bolts. Dynamic model including bearing pedestal looseness is established based on the dual-rotor test rig. Three-degree-of-freedom (DOF) planar rigid motion of loose bearing pedestal is full...
