【摘要】 对不同开孔率和不同厚度比的一系列球壳大开孔平齐接管结构进行了有限元分析 ,得出了不同开孔率及厚度比与连接处应力集中系数之间的关系曲线 .为验证分析方法的可靠性 ,对结构 ri/Ri= 0 .6、t/T=1 .5的模型容器作了应力测试 .两种方法所得结果基本吻合 .更多还原

【Abstract】 Using the finite element procedure ANSYS,graphs of stress concentration factor (SCF) were obtained by analyze a series of spherical shell with big nozzle in different t/T and r/R.For confirming the results,a full-size model(r\-i/R\-i=0.6,t/T=1.5) was analyzed by means of strain gauge test. The results accorded with each other basically.更多还原
