摘　　要：研究无人水下航行器壳体强度优化问题,由于随着下潜深度的增加,水下航行器受到的压力不断增大,传统水下航行器采用的壳体结构已不能满足强度要求。藕节形耐压壳体则结合了球形壳体和圆柱形壳体的优点,弥补了传统耐压壳体结构的不足。针对藕节形耐压壳体强度设计,利用有限元软件对不同厚度、不同切弧角下的强度和稳定性进行了分析,给出了最大应力和稳定性系数随厚度和切弧角的变化规律并分析了其原因,为大深度水下航行器的壳体结构设计提供了一定的参考依据。With the increase of deepness for unmanned underwater vehicle （UUV）, the traditional pressure hull cannot meet the requests of mission. Multiple intersecting spheres pressure hull has the advantage of both sphere and column forms, being an offset against the defieiency of traditional hull. The strength and stability of this pressure hull was analyzed, in view of the changes of thickness and tangent arc angel, using the method of Finite Element Analysis, and the reason for these changes, these results may provide some reference for the pressure hull designers.
