压力容器壳体局部应力计算和强度评定

The Calculation and Intensity Evaluation of Local Stresses on the Spherical Head of Reactor Subject to Inter Pressure

介绍了一种简便、实用的压力容器壳体局部应力计算方法,并应用该方法对一高压反应器底封头由接管载荷引起的局部应力进行了详细计算,进一步采用分析设计法进行了强度评定。

A method for calculating local stress on the shell of pressure vessel is introduced. By applying this method, the calculation of local stress caused by nozzle load on the bottom head of the reactor is made. The stress intensity at the location of nozzle attachment to spherical head is evaluated by analysis design pricniple.
