| Abstract: | According to the essential reasons for equipment failure of electrical locomotives,the failure root of traction subsystem for electrical locomotives is analyzed.Simultaneously,a novel life expectancy model for the traction subsystem is presented based on stress-analysis.This model adopts Miner rule and reliability theory to estimate the equipment maintenance life of electrical locomotives traction subsystem and to calculate the damage value of the key equipment,then to estimate the overhaul cycle of tractio... |
