基于等效应力的统一二次曲线拱坝体形优化设计
Optimization Design of Arch Dam Based on Equivalent Finite Element Stress
【摘要】 文章介绍在通用有限元软件ANSYS8.1平台上,研究以“有限元等效应力”为强度准则的统一二次曲线拱坝体形优化的实现。ANSYS特有的APDL参数化有限元分析技术,结合“有限元等效应力”可优化得到最优的拱坝体形。文中提出的方法可缩短设计周期、减轻设计人员的劳动强度。
【Abstract】 The equivalent stress method of finite element can alleviate accumulation of stress.ANSYS is power of calculation.The best curve of an arch dam,which is the most economic can be found by using the APDL analytical technique.The method presented in this paper can not only shorten the time needed for design of an arch dam but also reduce designers’ work intensity.
