Fixed-point rubbing fault characteristic analysis of a rotor system based on contact theory

In this paper, fault characteristics of a single span rotor system with two discs are investigated when the rubbing between a disc and an elastic rod (a fixed limiter) occurs. First, a finite element (FE) model of the rotor system is developed, a point–point contact model is established to simulate...
