THERMO-ELASTIC STRESS-STRAIN ANALYSIS FOR HOUSING OF ROLLING MILL AND APPLICATION OF COMPUTER GRAPHICS

机架是轧机最重要的零件。文中采用二维和三维相结合的方法求解其位移场和应力场,同时考虑了热轧时的温度效应。由于采用了有限元分析前后处理技术,计算模型和分析结果实现了自动生成和计算机图形显示。

Housing is the most important element of rolling mill.In this paper,a step method,which combine the 2-D and 3-D finite element analysis,was presented to solve it’s displacement field and stress field.The calorific effect in hot rolling procedure was also taken into this account. At the same time,the preprocessing and postprocessing based on the computer graphics were applied to set up the computational model and to show the eomputional results.
