【摘要】 本文描述了美国、前苏联、欧洲、日本和中国等国内外运载火箭跷振(POGO)抑制技术研究的发展历程及进展,并总结出国内外火箭POGO抑制技术的特点,以及在小POGO和气蚀动力学等方面带来的启示.美国的POGO抑制技术研究经历了大力神2——土星V——航天飞机——具体问题具体分析等4个阶段的发展历程,中国的POGO抑制技术研究也类似经历了331工程——载人航天工程——新一代火箭——40 Hz问题等4个阶段.由此可知,POGO振动抑制呈现出"事前理论预示难度大、事后危害后果严重、解决过程漫长曲折"的特点,必须在重大航天工程实施前开展研究.更多还原

【Abstract】 This paper describes the development process and progress of POGO suppression technology of launch vehicle at home and abroad, such as in the United States, the former Soviet Union, Europe, Japan and China. The characteristics of POGO suppression technology and inspirations of mini-POGO and cavitation dynamics are summed up. American POGO suppression technology has experienced the process of Titan 2—Saturn V—Space Shuttle—analysis of specific issues. Similarly, POGO suppression technology of China has also experienced the four stages of 331 project—Manned Spaceflight project—New generation launch vehicle—40Hz issue. It can be seen that POGO vibration suppression showed the following characteristics: difficult prior theoretical prediction, serious consequence and tortuous process of solution. It must be conducted research prior to the implementation of major aerospace project.更多还原
