    摘要:

    高超声速飞行器表面结构,如发动机叶片、内涵道及其排气道等暴露在高温强噪声复合环境中,容易出现热声疲劳损伤问题。因此,热声疲劳研究对增强这类结构的耐久性和可靠性具有重要意义,结构热声疲劳问题引起了广泛关注。本文总结了国内外在飞行器结构热声疲劳领域的研究现状,阐述了在热声疲劳理论研究、仿真分析和试验技术方面所取得的进步。从时间维度回顾了国外自20 世纪70 年代至今在结构热声疲劳领域的研究情况;按研究单位分类介绍了国内科研院所和高等院校在该领域所开展的工作。在此基础上分析了飞行器结构热声疲劳研究所面临的技术难点问题,指出了尚需进一步研究的方向。

    Abstract:

    The structures of hypersonic vehicle surfaces, engine baldes, internal ducts and exhaust ducts are pronse to thermal-acoustic fatigue damage when exposed to high temperature and high-intensity nosie environments. Thus, it is of more significance for improving the durability and reliability of such structures to study the thermal-acoustic fatigue problems. On the basis of literature review and summarization, this paper comprehensively ealborated on the new progress in the research of thermal-acoustic fatigue problems of aerocraft structures both domestically and internationally. Firstly, the research status of structural thermal-acoustic fatigue in foreign countries was reviewed from the 1970s to the present from a time perspective. Then, the work carried out by domestic research institutes and higher education institutions in this field was introduced according to the classification of research units. It showed that significant progress had been made in the theoretical research, simulation analysis and experimental technology of thermal-acoustic fatigue both domestically and internationally after half a century of development. The technical difficulties faced by the research on thermal-acoustic fatigue of aerocraft structures and the issues that need further research were also discussed at last.
