基于Visual Environment焊接模拟方法

摘要
焊接是现代制造技术中重要的金属连接方法。如今的焊接工艺更是深入几乎所有行业,如何利用最小成本确定最优的焊接工艺参数,是现在焊接领域的重点之一。而焊接的数值模拟是解决此类问题的有效方法。与最常用的有限元模拟软件相比较, Visual Environment不仅拥有独特的焊接工艺向导,而且操作逻辑相对简单。Sysweld与Visual Environment软件的安装是使用软件的基础,而且网上各种教程虽然繁多,但是破解步骤却残缺不前,尤其是Visual Environment。本文首先详述两种软件的安装破解方法,其次基于Visual Environment平台,将试板按V型坡口进行网格模型建立,并且将网格分组为六层焊接,每层2焊道,共计12焊道,并对其整个焊接过程进行工艺向导的设置,为后续的焊接参数优化奠定了基础。
Welding is used to connect metal in modern manufacturing technology. Nowadays, there is welding process in nearly all kinds of business. How to determine the optimum welding process parameters, using the lowest cost, is the key point in welding technology. And the welding numerical simulation is the effective method, which solves this problem. Comparing the common finite elements softwares, there is the welding process wizard, SYSWELD software has, in the Visual Environment. The manipulation logic of Visual Environment is simple. The installing of Sysweld and Visual Environment is the basis of using the software. There are many stalling courses in the Internet, but the crack steps are not full, especially for Visual Environment. There are two kinds installing steps of the software in the paper. Based on Visual Environment, the mesh model is established, and there are six layers in v-groove and there are two weld beads in each layer, adding twelve weld beads. The welding process wizard is set, establishing the foundation for the next optimization of welding parameters.
