摘　　要：针对侧线进料三通接管结构,采用比较规整的8节点六面体单元建立三维有限元模型,进行了有限元应力分析和应力强度评定。分析结果显示,此三通接管结构满足JB 4732—1995《钢制压力容器——分析设计标准》所规定的应力强度,并且有较大的安全余量,可以忽略较小的均匀腐蚀减薄量。The three-dimensional finite element analysis and the stress strength judgment were established by 3-D FEM model with eight nodes hexahedron element for the straight tee of side inlet feed. The straight tee of side inlet feed was convinced for the sufficient of strength reserve according to JB 4732--1995 《Steel Pressure Vessels-Design by Analysis》, the reducer of thickness at straight tee might be not considered.
