A Calculation Program for the Characteristic Frequency of Mechanical Fault Diagnosis

In order to solve the problem that the traditional fault diagnosis for the transmission system of self-propelled guns cannot access accurate fault locating due to the lack of effective methods (1), a program for calculating the characteristic frequency of the transmission system was developed. In this paper, we calculate the characteristic frequency of shaft, gears, bearings and other typical rotating parts and establish relatively complete database by the transmission regular on the basis of the engine crankshaft speed, so that we can make effective identification and feature extraction in equipment state detection and diagnosis.
