Abstract: In order to improve the warping distortion of the 125 MN stretching machine track after heat treatment in a large aircraft project, the distortion results were detected, combined with the data, theoretical and numerical simulation analysis were carried out, and the influence law of internal stress on heat treatment distortion was studied. According to the analysis results, by changing the enter way of the track into the quenching oil, the distortion of the track can be effectively reduced, and good results have been achieved in practical application, effectively improving the heat treatment distortion of the 125 MN stretching machine track.

Key words: track, warping distortion, stress, control
