【摘要】 救生钟和深潜救生艇是援救大型水下载体的核心载人潜水器,水下对接是其关键技术,是实现大型水下载体艇员和物资干转移的根本保证。失事报警浮标对于快速搜索失事大型水下载体和救生钟对接救生能力有重要影响。本文针对失事报警浮标在使用中存在的问题,提出了一种在静力平衡基础上叠加动载荷研究潜艇失事报警浮标动特性的方法,比对经过实践证明的既有文献提供的计算结果,证明了方法的有效性。分析了浮标在风、流、浪作用下的漂浮状态和受力规律,查明了浮标使用过程中存在被海水淹没、信号灯发出的灯光信号难于被发现、浮标缆断缆等问题的成因。针对存在问题,提出了改进思路。本文以提高救生钟援救大型水下载体效能为目的,提出了一种救生钟水下对接能力分析方法,采用该方法研究了海流和操纵因素影响救生钟水下对接的机理。分析了实装使用中引导缆断裂、无法实现对接密封和脱离耗时长的原因,提出了改进方法和对接操纵建议。采用了对接操纵建议后,明显提高了对接能力和安全性。本文以提高深潜救生艇援救大型水下载体效能为目的,提出了一种海流作用下深潜救生艇水下对接能力分析方法,采用该方法研究了海流和操纵因素影响深潜救生艇水下对接的机理。针对新型深潜救生艇,提出了改进方法。提出了基于模糊综合评判理论的深潜救生艇驾驶员操纵技能综合评价方法。将该评价方法用于2008年度深潜救生艇准操纵员第一阶段的考核,取得了良好的效果。本文设计了基于虚拟现实技术的深潜救生艇操纵训练仿真系统。计算了空间受力,发展了深潜救生艇六自由度运动方程。开发了驾驶员可以通过监视器所能观察到的多个外部清晰化小场景。以深潜救生艇虚拟仿真系统为测试平台,检验了深潜救生艇对接能力理论分析结果。更多还原

【Abstract】 Rescue bells and deep submergence rescue vehicles are main manned submersibles to resuce large underwater carriers. Their key technology is the underwater mating, which is fundamental guarantee for transferring personnel and material between an underwater carrier and a surface ship. A wrecking alarm buoy is the important factor to influence the time limit to search a wrecking large underwater carrier and the mating rescue ability of rescue bell.With a view to the problems of wrecking alarm buoy emerged in use, a method studying on its dynamic features is brought forward, which is adding dynamic loads on static balance and has been proved by comparing its calculating data with previous reliable literature data. The floatage state and Load rule of the buoy is analyzed. The causes are found of the buoy submersing in seawater, the alarm light signal ghosting and the buoy cable breaking off. Some ideas are put forward in order to solve the buoy problems.A method is brought forward which is used in analyzing the underwater mating ability of the rescue bell in sea current. And the ability is analyzed. The causes are discussed of the downhaul cable breaking off, mating seal failing, and breaking away sluggish. Some improvement measures and mating manoeuvre suggestions are put forward. The mating ability and security has been observably increased afer adopting manoeuvre suggestions.A method is brought forward which is used in analyzing the underwater mating ability of the deep submergence rescue vehicle in sea current. And the ability is analyzed. Some improvements measures are put forward for the new deep submergence rescue vehicle. A method evaluating the pilots’operation skills based on fuzzy synthetic evaluation theory is brought forward. And it is verified by the tests applied in the pilot candidates in 2008.Based on virtual reality, a steering voyage simulation system of the deep submergence rescue vehicle is designed. Employing the hydrodynamic wing theory, the hydrodynamic equations of the shroud is brought forward and solved. The underwater motion equations of the submersible are improved according to opration experience. Some clear outside virtual scenes are developed which may be seen by pilots with the help of video cameras. The theory analysis of mating ability is verified by the tests running on the simulation system.更多还原
