摘　　要：针对深水电磁发射大功率电源的特殊需求,设计了一种为电源、电子器件等设备提供安装空间的水密承压舱。对该承压舱的结构特点、密封形式和散热方式进行了研究。使用Pro/E软件建立了承压舱的三维模型,应用集成于Pro/E内的ANSYS Workbench软件对承压舱壳体强度、刚度和稳定性进行有限元分析,并对实物样机进行压力釜模拟外水压和全系统温升试验。结果表明:该承压舱能够承受的外水压不少于1000 m,电源模块最高温度稳定在90℃以内,结构、密封和散热设计合理可行,满足使用要求。本分析设计方法及验证结果为后续类似及更大水深耐压壳体的研制提供了参考。A deepwater pressure chamber that provides installation space for power supplies,electronic devices and other equipment is developed to meet the special requirements of high-powersupply for deepwater electromagnetic launch.The structure,sealing,and heat dissipation methods are designed and investigated.A three-dimensional model of the pressure chamber is established using Pro/E software.ANSYS Workbench software integrated in Pro/E is applied to conduct finite element analysis on the strength,stiffness,and stability of the shell of the deepwater power pressure chamber.The pressure vessel and the full system temperature rise test are conducted by using a physical prototype.The results show that the pressure chamber can withstand no less than 1000m of external water pressure,and the maximum temperature of the power module is stabled within 90℃.The sealing and heat dissipation structure design is reasonable and feasible,meeting the usage requirements,laying a technical foundation for the development of similar and larger deepwater shells.
