自主式水下航行器的耐压和密封是非常关键的两方面，基于SolidWorks软件对324型AUV耐压舱体进行了设计与仿真校核。综合考虑薄膜理论和不连续效应，根据NSGA-Ⅱ算法实现多目标优化，确定出直舱和封头的基本尺寸，利用美国海军试验水槽公式和稳定条件进行初步验证，以保证强度和稳定性。根据得出的几何尺寸在SolidWorks里完成三维建模，并在Simulation模块中完成数值模拟仿真，最终对舱体进行实际耐压试验，将结果和理论计算、软件仿真进行对比。针对直舱段舱体不同尺寸和材料进行了三维建模和数值仿真，得出相应结论。
Pressure endurance and seal of autonomous underwater vehicle are two key aspects. Based on SolidWorks software, 324 AUV pressure hull is designed and simulated. Incorporating the membrane theory and discontinuous effect, according to the NSGA-Ⅱ multi-objective optimization algorithm implementation, to determine the basic dimensions of the straight tank and head. Use tests the flume formula of USA navy and the stability condition for the preliminary verification, to ensure the strength and stability. According to the obtained geometric dimensions, three dimensional modeling was completed in SolidWorks. Numerical simulation was completed in the simulation module. Finally, the actual pressure test was carried out on the hull. The results were compared with theoretical calculation and software simulation. Three dimensional modeling and numerical simulation for different sizes and materials of straight section hull are carried out and get some conclusions.
