Method of Wheel Polygonal Fault Diagnosis Based on ATDR
A wheel polygon fault diagnosis method based on the advanced truck defect diagnosis and record system(ATDR)is proposed in this paper.Firtly,the vibration and shock signal of axle box are collected and diagnosed by ATDR.Then the on-board diagnostic status and alarm results are displayed through the ground software,and the polygon order is determined according to the wheel polygon fault characteristics,furthermore the suggestion for wheel repair is proposed based on the alarm results.Finally,line test and wheel out-of-roundness test are conducted to verify the effectiveness of the proposed method.The results show that the method based on ATDR can diagnose the wheel polygon order effectively,and the fault alarm result can support the wheel polygon wheel repair effectively.
