Abstract：

In order to simplify the analysis process of multi-pass roll bending for asymmetric Z-section profile and save the time of pre-processing and post-processing, ABAQUS secondary development was carried out based on Python language to improve the analysis efficiency and predict the roll bending accuracy. Then, the main control program of each module was written based on Python, and the main control program of each module was written as a subroutine into a script file. Furthermore, the GUI interactive interface program and interface program were designed by wx.Python library, and the pre-processing and post-processing function of ABAQUS secondary development were realized. In addition, under the environment advantage of secondary development, the combination of GUI interactive interface and script file significantly improved the speed of multi-pass roll bending test. In the roll bending comparative test under different working conditions, the results show that the simulation calculation error of ABAQUS based on Python is within 10% and the reasonable roll bending passes corresponding to different roll bending radii can be determined.
