焊有45°斜接管筒体结构的极限载荷分析

摘要

对应力分类法的局限及极限载荷分析法的优点进行了分析讨论，并采用数值有限元分析的方法对实际案例进行了极限载荷分析，详细介绍了计算过程及结果，通过比较极限载荷分析法与应力分类法计算出的筒体和接管厚度的差异，说明了极限载荷分析法的优势。%The limitation of stress classification analysis method and merit of limit load analysis method were discussed.Limit load analysis for a real structure was done by FEA.Detail calculation process and result were introduced.The advances of limit load analysis method were showed by compare cylindrical and nozzle thickness calculated by the two analysis methods.
