【摘要】 随着现代海洋军事的发展，潜艇的发展也越来越快，与此同时频发的潜艇事故也越来越受到人们的重视。目前的潜艇事故多发生在亚深海域，潜艇逃生是完全有可能的，但是传统的逃生方法存在效率低下，救援时间长等弊端，无法满足深海逃生的特殊要求。快速上浮逃生法是一种新型的高效自救方式，它可以在不需要外界帮助的情况下，实施逃生。本文针对快速上浮逃生法的工作要求，提出了一种快速加压试验系统，通过仿真研究确定了合适的控制策略，并通过陆上台架实验实现了加压过程的精确控制。本文首先论述了快速加压系统的工作原理，工作特点和工作要求，根据逃生环境的特点，提出了采用外部海水加压和艇内气源加压的两种快速加压方式，为系统设计和设备选型提供了依据。接着根据快速加压的工作要求，选择了气动先导式流量调节阀作为系统的核心控制元件。针对气动先导式流量调节阀的迟滞和非线性特性，借助AMEsim仿真平台，优选了模糊控制法。随后根据模糊控制器的工作原理及设计方法，通过仿真研究设计了快速加压系统的模糊控制器，提高了系统的动态性能，改善了系统的鲁棒性。在此基础之上，构建了由逃生舱系统、假海模拟系统、控制系统、高压气源等组成的快速加压陆上台架实验装置。最后，进行了现场实验，实验结果证明该系统的各项性能达到设计要求，能够实现快速加压过程的精确控制，验证了通过快速加压实现深海快速上浮脱险的可行性。更多还原

【Abstract】 With the development of modern marine military, submarine is developing fasterand faster, and at the same time more and more attention is being paid to the submarineaccidents. For most of the submarine incidents are in asia-deep waters, submarine escapeis entirely possible, but traditional escape methods have some drawbacks, such as lowinefficience and long rescue-time, they can’t meet the special requirements of deep-seaescape. Fast floating escape method is a new efficient self-saving method, which can beimplemented even without outside help. By analyzing the requirements of fast floatingescape method, an experimental system for fast pressurization was proposed, andappropriate control strategies was determined, and at the same time a precise controleffect of the pressing process was achieved by onshore bench experiments.Firstly, working principles, work characteristics and working requirements of thefast pressurization system were discussed, according to the characteristics of escapeenvironment, two pressurization methods were proposed, one was using the externalseawater, another was using the gas source from the submarine, which provided the basisfor the design and the equipment selection of the system. Then based on the workrequirements of the fast pressurization, pilot-operated pneumatic control valve waschosen as the core control element of the system.For valves had characteristics ofhysteresis and non-linear,fuzzy control was chosen with the help of AMEsim simulationplatform. Subsequently, according to the working principle and designing method of afuzzy controller, the fuzzy controller was designed for the fast pressurization system withthe help of simulation, and the dynamic performance and the robustness of the systemwas improved. On this basis, the onshore experimental device was constructed, whichconsisted of the escape pod system, sea-simulation system, control system andhigh-pressure gas source. Finally, by field experiments, the performance of the systemwas proved to meet the design requirements and was able to achieve the precise controlof the process, and the feasibility of fast compression to achieve fast floating escape fromdeep sea was proved.更多还原
