摘要
本文提书一种空间板块组合结构有限元网格自动生成的方法。其原理为:以等参单元形成刚度矩阵的形状函数为坐标变换式,将空间任意曲面或块体变换成规则图形子域,对规则子域进行划分,然后计算各节点在原坐标系中的坐标值。并且,开发了相应的程序,该前处理技术对于复杂的单元划分有重要的实际意义。
In the paper, a method of FEM mesh automatic generation for space plate structure is given. The principle is: taking the equal parameter unite to form a shape function as the trans form of coordinate; Spatial arbitrary surfaces or lump bodies are changed into small domains of regular figure; The regular small domains are divided into many lumps and then calculate every node's coordinate value which is in original coordinate. This method of earlier treatment has realistic significance for dividing the complex unite. The program of this method is developed.
