摘要
耐压球壳是载人潜水器的关键部件,对于载人潜水器的安全性、总体性能等诸多方面均有重要的影响。针对轻载作业型HOV耐压球壳的设计,确定了壳体材料、结构形式和主要尺度,完成了基于规范的耐压球壳强度校核和稳定性分析,设计了开孔加强结构,完成了基于有限元耐压球壳模型强度校核。最后,在考虑了材料非线性、初始缺陷等因素的基础上,采用弧长法完成了耐压球壳的稳定性分析。结果表明耐压球壳的设计方案满足规范要求,为深水轻载作业型载人潜水器耐压球壳的设计提供了参考。
The pressure-proof spherical shell is one of the key components of manned submersible,and has important influence on many aspects,such as safety and overall performance. Aimed at the design of the pressure-proof spherical shell of light load operational manned submersible,this paper determines the shell material,structural type and main dimensions,conducts the strength checking and stability analysis for the pressure-proof spherical shell based on specifications,designs the opening strengthen structure,and completes the strength checking for the pressure spherical shell based on finite element software. Finally,on the basis of considering the factors such as material nonlinearity and the initial defects,the Riks method is adopted to fulfil stability analysis for the pressure-proof spherical shell. Result shows that the design scheme can satisfy the requirements of specifications,and provides reference for the design of the pressure-proof spherical shell of light load operational manned submersible.
