摘　　要：海水密度、耐压结构体积、浮力材料体积以及液压油体积等随下潜深度的增加均会发生不同程度的变化,导致潜水器潜浮压载不匹配。潜浮压载直接影响载人潜水器在上浮、下潜过程中的速度控制以及在深海中的悬停、着陆和作业,因而对潜浮压载匹配方法的研究具有非常重要的工程实际意义。本文首先建立载人潜水器无动力潜浮运动数学模型,分析潜水器耐压结构、浮力材料和液压油的浮力损失,建立载人潜水器无动力潜浮运动压载匹配方法。通过与蛟龙号载人潜水器和深海勇士号载人潜水器的海试数据对比分析,有效验证了该方法的可行性和有效性。The density of seawater and the volumes of the pressure-resistant structure,buoyancy materials and hydraulic oil will change to different degrees with the increase of the diving depth,which leads to the mismatch of ascent and descent ballast.To investigate the direct effects of ascent and descent ballast on the speed control of a manned vehicle in the process of ascent,descent,suspension,landing and operation in deep sea,a mathematical model of a human-occupied vehicle is established to analyze the buoyancy loss of the pressure-resistant structure,buoyancy material and hydraulic oil,followed by establishment of a ballast matching method of the manned vehicle,the feasibility and effectiveness of which are verified by comparison and analysis of the sea trial data of Jiaolong manned vehicle and Deep-sea Warrior manned vehicle.
