摘要:

为了解决Msc.Marc有限元软件前处理条件器在焊接结构模型建立及网格划分复杂问题,针对某产品油箱结构中的焊接接头,利用Python语言作为二次开发的工具,提出并开发了基于Msc.Marc前处理模块的焊接接头特征库。同时结合Marc中的菜单语言,开发了专用的焊接接头形式菜单系统。该系统可以方便进行焊接问题的分析,提高设计接头形式的效率,并为扩展Marc功能、建立Marc专用模块及Marc汉化提供了良好的思路。

Abstract:

As the complexity and difficulty to create and mesh modeling of welded joint inMsc.Marc' s preprocessing system, a feature database of welded joint for the kind of oil box was developed with Python language.Meanwhile a new menu system based on welded joint feature was also established withMarc' s menu languages.These improvements of feature database and menu system make numerical simulation of welding process easier and design of welded joint faster. In addition, this method also provides good guidance of adding user special program into Marc and applying Chinese patch to Marc.

Key words: Marc welded joint menus feature database
