| 摘 要： | 通过几何制图软件，建立了某水下航行器壳体的有限元数值模型；在有限元分析软件中，对该模型进行了应力及关键部位的模态分析；确定了该水下航行器壳体结构的最大应力和固有频率等相关数值信息，避免结构设计缺陷导致的应力集中及共振问题。缩短了研发时间，减少了设计人员的工作量，降低了研发成本；同时，给壳体结构的改进指明了方向，为实体的顺利生产提供了可靠的参考依据。

| Abstract: | By geometric drawing software,it was established that a finite element numerical model of underwater vehicle shell,in the finite element analysis software,the structure stress and modal analysis of the key positions were did to deter-mine the maximum stress of the structure of the underwater vehicle shell and the inherent frequency and related numerical information,designing defects caused by stress concentration and avoiding structure resonance problems,lowing staff work-load and shortening development time,reducing the design and development costs,and at the same time,indicated the direc-tion to the improvement of shell structure,and provided a reliable reference basis for entities. |
