| 摘 要： | 潜艇内部舱壁采用贴板式支撑环与耐压船体连接,以消除耐压船体在舱壁处的应力集中.本文采用有限元方法计算分析了计及接触时支撑环应力的分布特点,指出规范计算的不足,并通过分析得到了支撑环的简化力学模型,最后对内置式贴板支撑环的设计提出了建议.

| Abstract: | The inner attached back-ring structure has been applied to submarine's bulkhead in order to reduce the longitudinal stress concentration of inner surface at the root of bulkhead.This paper studies the stress distribution of the back-ring structure considering contact with FE,and show the current rule's disadvantage.In addition,the simplified mechanic models of this structure are demonstrated.Finally makes an advance for the design of inner attached back-ring structure. |
