Abstract

Abstract

In order to analyze the effect of wheel-rail impact on the fatigue life of bogie frame, a bogie frame of a three-axle locomotive was taken as an example, the differential equation of wheel-rail impact was established, and the load history of wheel-rail impact was obtained by using Runge-Kutta formula. A finite element model consisting of wheelsets, bogie frame and carbody was established by using finite element method, the stress histories of different dangerous points on the frame were derived by using transient dynamics analysis technology, the S-N relations of 16 Mn material and fatigue damage cumulative rule were analyzed, and the fatigue life of the frame was calculated under the impact of wheel-rail tie-in. Analysis result shows that the stress response of the frame is not accordant with wheel-rail impact force to achieve the maximum value, but there is a longer response process after impacting; the influence of wheel-rail impact on the fatigue of bogie frame is great, especially, on the cover board of side-girder near axle box spring block, and the fatigue life of the frame is 5.15×10⁶ km under its malocclusion joint for 25.0 m long track.
