摘　　要：为简化非对称Z截面型材多道次滚弯成形分析过程,节省前处理及后处理时间,基于Python语言进行ABAQUS二次开发,达到了提高分析效率及预测滚弯成形精度的目的。基于Python编写各模块的主控程序,将每个模块的主控程序作为子程序编写为脚本文件,并利用wx.Python库设计GUI交互界面程序和衔接程序,实现了ABAQUS二次开发的前后处理功能。在二次开发的环境优势下,GUI交互界面和脚本文件的结合,使多道次滚弯成形试验的速度显著提高。通过不同工况的滚弯对比试验证明,基于Python的ABAQUS的模拟计算误差在10%以内,可用于确定不同滚弯半径对应的合理滚弯道次。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.
