摘要
对联苯锅炉上带偏置大开孔接管的封头进行了三维有限元分析 ,得出了接管、封头截面以及二者相贯线上的应力分布曲线 ,并按分析设计原理应用第三强度理论进行强度评定 。
The biphenyl boiler's head with a large offset nozzle was analyzed using three dimensional finite element method. The stress intensity distributions along the longitudes of the nozzle and head in the symmetrical plane , and around the intersecting area all showed that stress concentration exists in a narrow area around the intersection. The strength evaluation for the connection was carried out according to the China Standard of design by analysis: JB4732, and the results showed that the strength of the structure meet the requirements for safety.
