【Abstract】 In this paper,the diagnosis of multiple cause faults of rotor support is discussed.The diagnosis model and critical characteristic of multiple cause faults are derived by the wave pattern transformation analysis from the viewpoint of propagation feature of stress wave with punctation excitation.The presented model and conclusion are proved to be correct and effective through test and application of practical structure.更多还原
