摘　　要：风洞全模试验是验证飞行器气动性能的重要试验。悬臂支杆作为该类型试验中最普遍采用的支撑方式,具有结构简单、安装方便、支撑干扰低等优点,但也存在支撑刚度低、结构阻尼小等特征,导致易出现模型支撑系统的振动。在大型风洞和低温风洞中此现象发生得尤为频繁,甚至中断吹风过程。针对该问题,首先对风洞全模测力试验振动问题的历史发展及传统振动抑制方法进行回顾,接着对风洞全模测力试验的振动问题进行分析,然后介绍了国内外的基于压电的各类抑振原理及抑振结构型式,并对主动抑振算法的研究进行了综述,最后总结了抑振系统对气动系数的影响,并讨论了攻角扩展的相关结果。The full span wind tunnel test is an important test for validating the aerodynamic performance of the aircraft.As the most commonly used support system,the cantilever sting has the advantages of simplicity in structure,convenience in assembly,and low support interference,but it also has the characteristics of small support stiffness and low structural damping,which is prone to the model support system vibration.This phenomenon happens frequently in large size and cryogenic wind tunnels and may give rise to an interruption of the polar.Aiming at this problem,this paper first reviews the historical development and tradi-tional vibration suppression methods in full span wind tunnel tests.Then it analyzes the vibration problem of full span wind tunnel tests.Furthermore,various principles on the piezo-based vibrationsuppression and corresponding structure configurations are introduced,and research at home and abroad on the active vibration control algorithms is reviewed.Last,the paper summarizes the influences of the vibration-suppression system on the aerodynamic coefficient and discusses the results regarding the expansion of the angle of attack.
