风洞结构振动的基础研究综述

Fundamental researches on structure vibration of wind tunnel

国家在"十三五"期间启动设计建设大型低温高雷诺数风洞、大型连续式跨声速风洞、大型低速风洞等一批世界顶尖风洞设备,可以全面提升国家航空航天领域的创新能力。面向国家大型风洞设计建设中的重大需求,国家自然科学基金委员会第185期"双清论坛"凝练并提出了相关领域的关键科学问题,其中风洞结构振动是迫切需要解决的科学问题之一。本文围绕风洞结构振动的现象和规律,提炼出多场耦合诱导风洞结构振动的形成机理、传递过程和控制方法等基础理论和关键技术中极具挑战的若干问题,并针对大型风洞设计建设中面临的结构振动问题,给出了相关领域未来需要重点发展的方向建议。

During the 13th Five-Year Plan, our country launched the design and construction of serial ad- vanced wind tunnels, including large cryogenic wind tunnel, large continuous transonic wind tunnel and large low speed wind tunnel, to improve the national capability in the field of aeronautics and astronautics. To meet the significant demands of these major engineering, the 185th Shangqing Forum was held by the National Natural Science Foundation of China to summarize the key scientific issues on the design and con- struction of large wind tunnels, where the structure vibration is an increasingly imminent problem to be re- solved. Around the structure vibration phenomenon and regularities of wind tunnels, some challenging is- sues in the fundamental theory and key technology, such as the production mechanism, transfer process and control method of structure vibration, are pointed out in this work. Finally, some key research direc- tions are suggested to resolve these key scientific issues.
