深海载人潜水器下潜和上浮通常采用无动力下潜和上浮的运动方式。本文以载人潜水器受力分析为基础，基于经验公式估算方法，建立载人潜水器无动力潜浮运动预报模型；以“蛟龙”号载人潜水器和“深海勇士”号载人潜水器为研究对象，采用所建立的潜浮运动预报模型对无动力潜浮运动进行预报，并将预报结果同海上试验数据进行对比。结果表明，本文建立的预报模型的潜浮运动速度预报结果与海试结果的变化趋势基本一致，误差在12%以内，验证了本文所建立模型的可行性和有效性，能够在论证阶段或设计初期，为深海载人潜水器无动力潜浮运动的预报提供有效的技术手段。
Deep-sea manned submersible dives and floats usually employ unpowered diving and floating motions. In this paper, based on the force analysis of manned submersible, an unpowered submerged motion prediction model of manned submersible is established based on the estimation method of empirical formula. This study employs the manned submersibles “Jiao Long” and “Shen Hai Yong Shi” as research subjects and utilizes the validated submerged motion prediction model to project the unpowered submerged motion. The findings are then contrasted with the sea trial data. The findings demonstrate that the projected diving and floating motion velocity of the predictive model developed in this study aligns closely with the observed trend in the sea trial results, with a maximum discrepancy of 12%. This validates the efficacy and accuracy of the model established in this study and establishes its potential as a valuable tool for predicting the unpowered diving and floating motion of a deep-sea manned submersible during the demonstration phase or the initial stages of design.
