跨音速飞行中，激波-附面层干扰会引起激波周期性自激振荡，这种现象称之为跨音速抖振。跨音速抖振引起的脉动载荷有可能引发飞行事故或造成结构疲劳，该问题一直是航空领域的研究难点。本文从风洞实验和数值模拟两个方向总结了跨音速抖振研究的主要方法，重点综述了近几年在跨音速抖振机理研究方面以及结构运动对抖振响应特性的影响方面取得的新进展，简要总结了跨音速抖振的被动控制及主动控制方法。在此基础上，提出了跨音速抖振后续研究的重点方向：抖振机理的进一步探究，结构弹性特征对抖振特性的影响以及闭环主动控制等。

Transonic buffer is a periodically self-sustained motion of the shock induced by the shock boundary-layer interaction. Flight accidents and structural fatigue may be caused by the related ongoing oscillating loads in transonic flight. First, an investigation of the status of the current advances in the researches on transonic buffet is presented in this paper, and some main methods based on wind tunnel experiments and numerical simulations in recent years are reviewed in detail as well. Besides, the attentions are focus on the transonic buffet mechanism and the new progress on the effects of the prescribed structural motion on the characteristic of buffet loads. Some passive and active control me-thods are also involved briefly. At last, the important prospects in future transonic buffet investigations, which are the thorough study on the transonic buffet mechanism, the effects of airfoil elastic characteristics on transonic buffet cha-racteristics and the design of control law based on closed-loop active control are proposed.
