    摘要:

    针对无法连续模拟大型曲面薄壁件铣削加工变形的问题,利用Python脚本语言对ABAQUS软件的前处理模块进行了二次开发,通过开发的切削力动态加载Python脚本程序,解决了大尺寸曲面薄壁件加工变形的预测问题。实例模拟计算表明,仿真结果符合实际规律,证明利用有限元二次开发技术可以较好地预测大型曲面薄壁件的加工变形,为其在其他领域的应用提供了参考。

    Abstract:

    In view of the problem of unable continuous simulation for large curved surface thin-wall parts milling deformation, Python scripting language is used in pre-processing module of ABAQUS for secondary development. Through the Python script program for the cutting force dynamic loading, the machining deformation prediction problem for large size curved thin-walled parts was solved. The sample simulation and calculation show that the simulation results accord with the actual rule, which proves the machining deformation of large size curved thin-walled parts can be better predicted by using finite element secondary development technique, it provides reference for its application in other fields.
