Simufact.welding
——高端焊接工艺仿真软件
simufact.welding软件采用windows操作风格界面,极易使用,即使没有CAE软件使用经验,也能很快掌握使用,并得到精确的计算结果。
Simufact焊接模块是一个基于有限元法的前后处理界面,可以很简单的创建多机械手仿真模型。每个机械手均可以根据用户需求自行定义多条焊接路径。焊接方向和路径很容易通过程序进行修改。用户可以根据实际工艺定义几何边界条件,如:完全固定、有预紧力的夹紧工具、支架等。
2种不同的热源模型可供用户选择:
 3-D高斯体积热源
 高斯表面热源
支持的求解器:
 IFE Weld
 MSC.Marc
两种求解器均为包括传热和变形的有限元求解器。都有强大的非线性和材料属性功能。
 与温度和力相关的温度表格定义
 与温度、应变、应变速率相关的材料屈服应力曲线
 微观组织也可以进行仿真
后处理简单易用
工件的扭曲变形可以放大缩小/与原结构进行对比
温度、应力、应变以及其它结果在仿真中实时可见
冷却后的残余应力分析
焊缝区域细微的传热分布
工件可任意切面观察
工件几何形状通过NASTRAN格式导入(六面体/壳单元)
Simufact焊接模块是基于Windows操作系统开发的。所有的几何模型和物理数据均放置在目标区域,焊接工艺仿真在进程树中定义。通过鼠标简单的拖拽便可将目标区域的几何模型和物理数据拖拽到进程树中,目标区域的所有几何模型和物理数据可在不同工艺仿真中运用,以此来对比不同工艺带来的仿真结果变化。
Simufact焊接模块已经为用户定义好获得最佳结果的相关参数,用户只需进行简单设定便可以进行焊接仿真。通过输入数据,用户可以获得最佳的仿真结果,如:变形、残余应力以及微观组织。 通过Simufact焊接模块用户可以通过预先定义好的参数和设置来对高度非线性焊接工艺进行仿真,无须学习更多的相关知识。 通过简单的菜单便可以定义多个焊接机械手,每个焊接机械手均可以定义不同焊接路径、工艺间隙、传热和焊接均可详细定义。
Simufact.welding is a customized software solution for analysis and optimization of welding processes. The central task of Simufact.welding is the examination of welding distortions. Moreover, the analysis of heat affected zones helps the expert to draw conclusions on the properties of welding seams.
Simufact.welding supports welding specialists and engineers in the layout and test of welding processes. Simufact.welding is easy to use and therefore, virtual process design and optimization can be applied in close relation to production for the first time ever.
The use of Simufact.welding permits an accurately timed control of several robots, an easy modification of welding sequences, speed, heat input, stop times, or fastening devices. Quick evaluation of process variants by change of welding parameters leads to systematic optimization of fusion zones, heat affected zones, residual stress and distortions. The software provides extensive tools for reporting, among others for the display of distortion, temperature distribution, residual stresses, curve progression of physical factors on fixed measuring points as well as several export interfaces. Most different ways of description such as dynamic cuts through the welding seam, flexible views and detailed x-y-diagrams enable a quick and efficient analysis of the welding process.
The functions of Simufact.welding at a glance:
- pre- and post-processing within one GUI
- no data conversion
- fast presentation of results
- result evaluation simultaneous to computation
- interactive graphical sequence control of robots and clamping tools
- section views of all result values
- “Weldmonitor” (trip to all welding seams in a 2D section)
- measuring point diagrams for comparison with test welds
- progress indication of calculations with access to already calculated results during the analysis
- context support for all input areas
- interface to RoboCad as well as export interface to robots
- Dual Solver Technology: optimized MSC.Marc Solver, IFE WELDSIM Solver
- different heat sources (Goldak model, cylindrical
- comparison of simulation results with real micro sections through “Weldmonitor”- function
- real stress conditions
- welding paths in real speed, direction and inclination
