接管轴向外力对压力容器强度的影响

Analysis on the Influence of Nozzle Axial Force to the Strength of Pressure Vessel

接管部位的应力分析是压力容器分析设计中最常见的分析模型,大多数压力容器的接管都承受外力的作用。文中通过实例分析了作用在接管端面上的轴向外力对承受内压的压力容器接管部位的强度计算结果的影响。探讨了接管轴向外力的方向与大小对不同类型容器壳体的影响规律。

Nozzle stress analysis is conventional in design by analysis of pressure vessel.Most nozzles of pressure vessel is applied with the load of outer forces.This thesis made an analysis on the influence of nozzle axial force to the strength of connection parts of pressure vessel nozzle under inner pressure according to the concrete examples.The rule of influence of the different direction and amount of forces to the different kind of shells is discussed.
