摘要
潜艇结构水下碰撞是潜艇的主要事故形式,也是船舶碰撞最为危险的状态之一。文中首先提出潜艇碰撞问题,对碰撞特征进行分析,然后针对某型潜艇舯部典型结构的撞击极限强度特性进行数值计算,结果显示,由于准静压载荷的附连耦合作用,随着静水压力的增加,潜艇舯部耐压壳体结构的防撞能力将大幅下降,而耐压壳体内部平台和舱壁结构将有效提高壳体结构的横向失稳临界应力,改善潜艇结构的径向耐撞能力。
The collision of submarine structure under water is a main accident form and one of the most dangerous states for ship collision. However, the research on submarine collision under water is rare now. The problem of submarine collision is put forward, and its characteristics are discussed firstly in this paper. And, the characteristics of collision strength for a certain type submarine structure is numerically analysized. The calculation results show that： With the water pressure increasing, the collision resistance ability will decrease, and the reinforced structure, such as flat and bulkhead, will be advantaged for flexure resistance increasing. Those inner structure will improve the radial collision resistance ability of submarine structure under transverse impact loading.
