The pedestal looseness fault is one of lower recognition rate fauts in the rotating ma-chinery at present. The recent research status and progress about the study on rotor system of ro-tating machinery with pedestal looseness faults were summarized, including the main studying a-chievement of nonlinear characteristics analysis methods and complex dynamic characteristics, couping faults, fault diagnosis and model experiment, etc. Then the problems for solving in the research of pedestal looseness faults of rotating machinery are pointed out, and the research trends of fault diagnosis in rotating machinery with pedestal looseness are prospected.
