摘要: |
针对内置式耐压液舱结构的应力变化规律,对比分析了不同载荷工况下,两种不同液舱顶板结构形式及变截面肋骨对液舱壳板的变形和应力的影响。结果表明:对于不同的液舱顶板形式,变截面肋骨角度β存在最优值;在液舱周向范围一定的情况下,肋骨肋板间的连接形式对液舱顶板纵向应力影响显著,而β主要影响液舱顶板的周向应力。 |

Abstract: |
For inner pressure tank, with the comparison of stress variation of pressure tank frames at two different forms of connection, the influence of different loading conditions on deformation and stress characteristics of the tank shell plate was analyzed. The results show that for different connection forms, the best angle β between the section changing location and the tank top plate exists with each form. In the circumferential range, different schemes mainly affect the tank top plate longitudinal stress and the circumferential stress of the frame and rib is affected by the β values. |
Keywords: inner pressure tank circumferential connection stress analysis |
