| 摘 要： | 为满足某工艺要求,对切向斜接管结构进行了修改设计——沿斜接管轴向一定角度切割斜管,并用直面板补足缺口。此设计使得斜接管与筒体连接复杂,连接区域几何非连续性非常严重。确定压力容器的临界载荷及其相应的失稳模态,是压力容器分析设计的重要组成部分。采用非线性屈服分析方法,对这一带有异形切向接管的圆柱形压力容器在外压状态下的稳定性进行了分析。计算结果可为容器的安全使用提供保障,也可为同类设计提供借鉴。

| Abstract: | For the technical requirements,tangential nozzle structure is modified that tangential nozzle is cutted at an angle along the axis of the tangential nozzle,and the notch is filled up with a plate.The joint structure between nozzle and vessel will be very complex in this design,so the noncontinuity of the geometrical shape of the joint structure is very serious.Solving the critical load and the corresponding buckling modal of the vessel is an important part of analysis and design.The stability of a pressure vessel with special tangential nozzle is analyzed using nonlinear yield analysis method under the external pressure.The result can provide security for pressure vessel use and guidance for other similar design. |
