Construction of Transmission Box Fault Diagnosis System

This paper established a set of fault diagnosis system for the fatigue test of the drive axle and transmission. The fault diagnosis system includes two parts: hardware and software. The hardware part is the basis of data acquisition and warning signal output; the software is programmed to realize human-computer interaction, data sampling and storage, signal processing and fault diagnosis on the basis of hardware. In this paper, we introduced a fault diagnosis method based on vibration analysis and the concept of feature vector, according to the feature vector could determine the fault type. Finally, the reliability and practicability of the system are verified by a laboratory test.
