摘要

Propeller fault diagnosis is of great significance to the maintenance of power system of remote control aircraft. In this paper, the advantages of VMD decomposition in fault extraction of underwater UAV are fully utilized through the ROV propeller fault experiment.The stability of modal components is analyzed by AR spectrum. The cumulative energy of vibration signal is obtained, and the fault diagnosis of propeller is realized by comparing and analyzing the normal state and fault state atlases of two kinds of propellers.
