Abstract:The loose of mechanical parts is one of the common failures in rotating machinery. The current researches of loose fault mainly focus on non-rotating components. However, the loose of disc, which is the main work part in the rotor system, is less paid attention, and the mechanism and dynamics characteristics of the loose fault are also almost ignored. In this paper, a dynamic contact model of the rotor system with loose disc is established considering the microscopic surface topography. Through the numerical s… Show more
