铝合金耐压结构设计分析与试验验证

Design Analysis and Test Verification of Pressure Structure of Aluminum Alloy

根据水下潜器总体性能要求,按照最小重量原则,结合规范和有限元方法设计工作潜深为500m的铝合金带加强筋形式的圆柱耐压舱,并通过压力筒加压试验,对Ansys有限元静力分析的精确度进行了验证,为耐压结构设计与校核提供重要参考.

According to the overall performance requirement of underwater vehicles and the principle of minimum weight. The precision and finite element method was used to design the pressure chamber of the aluminum alloy material, which is the cylindrical structure with stiffeners and can reach 500 meters of work depth. The pressure test with strain gauge was carried out in a pressure cylinder. The accuracy of finite element static analysis of ANSYS is verified to a certain extent, which can provide reference for the design and checking of pressure resistance in engineering practice.
