Abstract
In order to solve out the issues of the fatigue life of the locomotive DF4, the P-S-N curve of the specimens and the technological skills of the manufacturers Qishuyan, Datong and Luoyang as well as the fatigue-strength reduction factors and the allowable stresses are identified based on the indoor experiments. Through the field tests, the stress spectrum is gained, the calibration coefficients of the instrumented wheel-set are obtained and the lateral and vertical load spectrum as well as the stress spectrum is calculated and analyzed according to different work conditions. According to the preliminary analysis, the fatigue life of the wheel-set is 17 years.
