摘　　要：针对空间杆系结构有限元计算结果的特点 ,提出了一种适合于空间杆系结构有限元计算结果图的生成方法 .利用有限元计算结果文件生成变形图、计算截面的内力图、应力图 ,用图形直观地显示杆系结构受力变形的情况及其用户所感兴趣单元上的内力和应力情况 ,并给出了QTZ2 5型塔式起重机的有限元计算结果图的生成算例 .该方法生成速度快 ,算法简洁 .Aimed at the feature of FEM analysis data of space pole structure, a graphics generation method of these data suitable for this kind of structure is presented. The FEM analysis data are employed to generate deformation curves of the structure, force diagrams of pole cross sections, and load deformation curves of them as well, so that the load deformation condition of the pole structure and the inner forces and stress condition of the elements that the users are interested in are shown visually by means of graphics. The graphics generation process is illustrated by an analysis of tower crane QTZ25, exhibiting fast generation and simple algorithm with the method presented.
