| Abstract: | Wheel-axle is one of the key parts in the running gears of railway cars.The machining is the last processing stage of wheel-axle,and the good or the bad of the processing technology affect directly the mechanical performance and fatigue life of wheel-axle.In this paper,on the basis of analyzing the main machining factors affecting the fatigue life of wheel-axle,the regular pattern of effects of residual stresses by machining upon the service life of wheel-axle is researched through test and simulation analysis measures,and measures and suggestions for control of residual stresses are given. |
