可视化技术在水轮发电机热变形及热应力分析计算中的应用

Application of visual technology in thermal deformation and stress analysis of hydroelectric generator

论述了在微机Ｗｉｎｄｏｗｓ９５工作平台上采用计算机图形技术和方法，对水轮发电机热变形及热应力有限元分析计算的大量结果数据进行可视化处理，以图形等方式表现出来，供工程设计人员快速清晰地了解分析计算结果。所研制的软件由ＶｉｓｕａｌＣ＋＋、ＦｏｒｔｒａｎＰｏｗｅｒＳｔａｔｉｏｎ计算机语言和三维图形库工具软件ＯｐｅｎＧＬ等实现，是长江三峡水轮发电机组关键技术基础性研究内容之一。

This paper introduces a new method, in which, the mass data comes from finite element analysis for the thermal deformation and thermal stress of hydroelectric generator is described in graphics by use of computer graphics technique and visual processing on the work plat of PC installed with windows 95 operating system. It can provide better understanding of the calculation results. The software is programmed in Visual C++ Fortran PowerStation and OpenGL.The issues described are one of the key foundational researches of the Yangzi Three Gorges hydroelectric generator.
