When the chassis of a freight car is reassembled, it is necessary to make holes on the summer beams of the frame. In order to evaluate the effect of making holes on the fatigue strength and life of the whole frame, the stress analysis and life calculation of the freight car frame are carried out under four common working conditions with finite element analysis software based on the finite element theory, combined with the load, fatigue type and frame material parameters of semi-trailer tractor.After analysis, it is found that the stress level of the whole truck frame is below the fatigue limit of the material after making holes of the truck frame, and the life of the strength meets the design requirements of refitting.
