| 摘 要： | 通过对球罐支柱与球壳连接最低点a的局部应力分析、讨论,总结出了a点附近局部应力的分布和变化规律。并认为在球罐设计中,与支柱相连接的赤道板和其他球壳板宜采用不等厚度,以降低a点附近的应力强度。为球罐的优化设计提供了切实可行的借鉴方法。

| Abstract: | Distribution and varying regulation of local stress adjacent to point A was summarized by local stress analysis on the lowest connecting point A of shell where is connected with the support of spherical tank.It is considered that equatorial plate and spherical shell plate,which is connected with the supports,can be in different thickness so as to decrease stress intensity adjacent to point A in design of spherical tank,which provides a practice method to optimally design spherical tanks. |
