| 摘 要： | 有限元建模往往是非常繁琐的过程,前处理软件的镜像功能可以大幅提高对称结构的建模效率,然而对于常用的前处理软件来说,尚没有一种可以完全（或完整）的将节点和单元编号进行偏移并保留单元属性、保留梁单元端点偏置和单元坐标系Y、Z轴的镜像功能。对复杂模型来说,手动对节点或单元重新编号或重新赋属性的工作量是巨大的。介绍了基于Hypermesh环境,利用TCL/TK语言开发的增强功能的镜像工具。通过两个实例验证,该程序可以提高有限元建模工作效率,减少繁琐的重复性工作。

| Abstract: | FEA modeling is a fairly complicated process,the efficiency of modeling a symmetrical structure could be greatly promoted by using pre-process tools. Nevertheless,there is no available tool for conveniently reflecting the FEA model which includes beam elements with node and element id offsets,properties,element geometry offsets and element coordinate systems. It's quite time consuming for the stress engineers to renumber the nodes and elements,reassign the properties or update the element coordinate systems... |
