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 dynamic equations of the cable in different ocean currents are developed in the natural co-ordinate, the effects of normal and tangential components of the fluid drag are both considered. The parame-ter expressions for the cable geometry and tension of the neutral cable under the action of uniform, linear and combined current flow are established. The physical laws of the cable geometry and tension distribu-tion in different currents are obtained. Also, the mathematical approach to the fast convergence of the nu-merical integration is pointed out. Some typical examples are calculated by the self-compiled program. The quantitative results further verify the physical laws, and show that ignoring tangential resistance is not ap-propriate for long cable.
