摘要
采用三维有限元应力分析方法对带切向接管的圆筒形压力容器进行了计算,并用电测实验对其计算结果做了验证,二者吻合良好。计算结果表明,该切向接管的最大应力集中系数低于相同尺寸径向接管的最大应力集中系数。
This paper analyzes the stress distribution around a tangential nozzle in a cylindrical pressure vessel with the finite element method. The results of caleulation by FEM are coinsident with those obtained by a strainometer test. The analysis shows the maximum stress concentration coefficient of this tangential nozzle is smaller than that of its raqial counterpart.
