摘　　要：ABAQUS对塑性成形进行数值模拟的后处理功能不够全面。为扩展后处理的功能,更好地查看和分析模拟的结果,本文提出使用Python语言对ABAQUS后处理进行二次开发来达到这一目的。文中探讨了二次开发实现的原理,以及其中文件的读写与复制、数据读取与处理、结果输出与查看等关键技术,并以一个厚度处理的实例来说明。结果表明使用Python对ABAQUS模拟产生的结果数据库进行处理,可以得到所要查看的厚度数据,从而为浏览结果以及指导后续的模拟优化提供了便利。For plastic forming, post-process functions provided by ABAQUS are insufficient. In order to extend post-process functions and examine simulation result effectively, this paper provides a method by using python to make second develop on ABAQUS post-process. In this paper, the principle of second-develop and some key technology, such as read-write of file, data access and computing, result export and viewing are discussed. For instance, a program of computing thickness is provided. The example indicates that second-developed ABAQUS post-process using python can view thickness easily and helps to analyze simulation result and optimize forming process.
