圆柱形薄壳压力管道的内力分析

Analysis of the Internal Force on Cylindrical Shell for pressure Tube

本文从分析具有刚性环的圆柱形薄壳,承受内压力时在刚性环附近产生的局部性的弯矩和剪力,从而论证同类型的压力容器为何多在环向焊缝附近并沿环向爆裂的原因所在。

This analysis the partial moment and shearing which is born of rigid ring of the cylindrical shell when it is bearing the internal pressure and proves the cause of burst for the similar pressure tube and the reason why it often happens at the ringed welding.
