深海浮标反应舱的设计与有限元仿真

Design and Finite Element Simulation of Reaction Module for Deep-Sea

为了帮助极地深海设备平台解决穿透冰层的问题,深海浮标上搭载了一种反应舱加热装置。该装置是一个封闭式圆筒化学反应容器,其四周是外径为180 mm的铝合金筒体,上下底面采用端盖进行密封,并且内部穿插了各种管道。在设计方案基础上对反应舱进行耐压设计,采用SolidWorks软件和ANSYS Workbench软件对反应舱壳体进行结构设计及静力学有限元仿真分析。研究结果表明:该反应舱壳体的筒壁和端盖厚度均设计可靠,在水下375 m压力环境下工作时所受的等效应力和变形均在安全范围之内。

In order to help the polar deep-sea equipment platform to solve the problem of ice penetration,the deep-sea buoy is equipped with a reaction chamber heating device.The device is a closed cylindrical chemical reaction vessel surrounded by an aluminium alloy cylinder with an outer diameter of 180 mm,sealed by end caps on the top and bottom surfaces,and interspersed with various pipes.Based on the design scheme,the reaction chamber is designed to be pressure-resistant,and the SolidWorks software and ANSYS Workbench software are used for the structural design and static finite element simulation analysis of the reaction chamber shell.The results of the study show that the cylinder wall and end cap thickness of the reaction chamber shell are designed reliably,and the equivalent force and deformation suffered when working under the pressure environment of 375m underwater are within the safe range.
