随着海洋资源开发与深海探测技术的不断发展，水下激光通信近年来逐步成为研究热点。本文以水下激光通信耐压舱为研究对象，根据耐压舱的结构特点和设计目标，提出一种采用钛合金舱体与蓝宝石光窗的耐压结构方案。围绕耐压舱设计方案开展理论分析，研究评估耐压舱的结构强度和极限承载能力。建立耐压舱结构实体单元有限元模型，基于Bilinear弹塑性模型和Mooney-Rivlin超弹模型对耐压舱结构安全和密封性能进行仿真计算。计算结果表明，本文关于耐压舱的结构设计与评估结果正确可靠，光窗密封结构合理可行，可以为水下激光通信耐压舱的工程设计提供依据。
With the continuous development of marine resource development and deep-sea exploration technology, underwater laser communication has gradually become a research hotspot in recent years. The paper takes the underwater laser communication pressure chamber as the research object. Based on the structural characteristics and design objectives of the pressure chamber, a pressure structural scheme using titanium alloy cabin and sapphire light window is proposed. Theoretical analysis was conducted around the design scheme of the pressure chamber, and the structural strength and ultimate bearing capacity of the pressure structure were studied and evaluated. Establish a finite element model of the solid element of the pressure chamber, and simulate the safety and sealing performance of the pressure chamber based on the Bilinear elastic-plastic model and Mooney Rivlin hyper-elastic model. The calculation results indicate that the structural design and evaluation results of the pressure chamber in the article are correct and reliable, and the sealing structure of the light window is reasonable and feasible, which can provide a basis for the engineering design of underwater laser communication pressure chamber.
