摘　　要：水下稳性是深海载人潜水器重要的总体性能之一,通过稳心高(GB)衡量潜水器的稳性,其指标大小与潜水器的操纵和安全息息相关。潜水器在运动过程中,海洋参数随深度变化以及潜水器自身压载变化引起潜水器稳心高发生变化。本文以稳心高基本公式为基础,结合潜水器耐压结构、浮力材料和液压油的浮力损失计算方法,建立深海载人潜水器水下稳心高数学模型,提出一种深海载人潜水器水下稳性分析方法。以“深海勇士”号载人潜水器为研究对象,对深海载人潜水器的水下稳性进行计算分析,得出深海载人潜水器水下稳心高的变化规律,可为深海载人潜水器的设计提供参考。Underwater stability is one of the important overall performances of deep-sea human occupied ve⁃hicles(HOVs).The stability of HOVs is measured by metacentric height(GB),which is closely related to the operation and safety of HOVs.The metacentric height of HOV changes due to the change of ocean parameters and its own ballast during movement.Based on the basic formula of metacentric height and the buoyancy loss calculation method for HOV pressure structure,buoyancy material and hydraulic oil,a mathematical model of metacentric height for HOVs was established in this paper,and a method of underwater stability analysis for HOVs was proposed.Taking“SHEN HAI YONG SHI”HOV as the research object,the underwater stabil⁃ity of HOVs was calculated and analyzed,and the variation law of the metacentric height of HOVs was ob⁃tained,which can provide a reference for the design of HOVs.
