中文摘要:
      随着海洋建设的高速发展,水下固定式、潜浮式与移动平台等多场合对电子舱应用兼容性的需求 越发迫切,这对电子舱的结构强度、密封、耐腐蚀、轻量化以及散热提出了综合性的要求。 文中在多因素约束的条件下介绍了电子舱的详细结构设计过程,舱体采用刚度较好的圆筒,端盖嵌套双层 O 型密封圈,这样的组成方式达到了水密性要求。 基于有限元仿真分析方法对 3 种常用抗腐材质的圆筒的壁厚参数和散热效果进行仿真计算,通过综合对比最终选用壁厚为 19.5 mm 的铝合金作为结构材料,在水深 2 000 m 环境下结构强度安全裕度系数达 1.5,并具有较好的轻量化和散热性能,可兼容多平台应用。
英文摘要:
      With the rapid development of ocean construction, the demand of multiple utility compatibility of electronic cabin used in underwater land-based, submerged and movable platform becomes more and more urgent. This puts forward comprehensive requirements for the structural strength, watertightness, corrosion resistance, lightweight and heat dissipation of the electronic cabin. The detailed structure design process of the electronic cabin under multifactor constraints is described. The electronic cabin is composed of cylinder and end caps with two round sealing ring. The cylinder has good stiffness. This composition satisfies the wa- tertightness requirement. The thickness and the heat dissipation effect of cylinders using three usual corro- sion resistant materials are computed by finite element method. Finally, aluminum alloy with 19. 5 mm thickness is selected as structure material after comprehensive comparison. The safety factor of structural strength reaches 1. 5 under the condition of 2 000 m water depth, and the structure has good lightweight and heat dissipation properties and is compatible with multiple utility.
