深海耐压结构观察窗蠕变变形分析

Creep analysis on deep-sea structure’s viewport windows

大深度耐压开口结构的设计问题是深海探测装备研制过程中的关键技术问题之一。作者曾针对深海耐压开口结构的受力变形、蠕变以及耐压壳体变形协调等问题进行了计算分析和试验研究,并给出了观察窗应力的理论计算方法。文中进一步从理论上给出观察窗变形分析的计算方法和观察窗蠕变变形的计算公式。由此可对深海耐压开口壳体接触界面变形协调与水密技术进行理论方面的探索研究,为形成深海耐压开口结构优化设计的理论计算方法及相关技术标准的制定提供理论方面的支撑。

Human occupied sphere is the key component for deep-sea Human Occupied Vehicle（HOV）.The difficulty of human occupied sphere design is the large openings such as human access opening and view windows opening.View windows usually are made of organic glass.In this paper,the stress,creep and boundary condition influences on windows of deep-sea HOV are analyzed by theoretical analysis and test.The theoretical calculation method is obtained.This paper can be used as a reference for such type of structure design.
