摘要
该文采用了先将整体结构分成子块进行剖分、后组合成整体的思路，并提出了整数空间坐标系的概念，成功地解决了子块之间的联接和边界条件处理等难点，建立了一套适合于三维结构的有限元前处理方法．并研制了汽轮机叶片有限元前处理程序，成功地应用于叶片三维有限元分析．
Abstract Making use of the idea of discretizing an integral structure by parts into elements and then assembling them to form the integral body,the paper presents the conception of a coordinate system of an integer domain,herewith solving the problem of joining the parts and handling the boundary conditions.Thus a finite element preprocessing procedure,suitable for three dimensional structures,is worked out. A finite element preprocessing program for steam turbine blades has been developped which has successfully been used for their 3-D finite element analysis.
