摘　　要：介绍了目前国内外对于飞机抖振问题研究的进展。主要介绍了目前国外对于飞机跨音速激波 附面层相互作用诱导的机翼抖振、低速大攻角下分离流诱导的机翼抖振、垂尾抖振的试验和理论研究方法、研究成果以及发展趋势。另外 ,也简单介绍了垂尾抖振减缓的几种方法 ,并对这些方法作了评述。In this paper, the present studies for the buffet of aircraft are summarized, mainly including those of the wing and tail buffets. The mechanisms, research methods, results, and tendency to these kinds of buffets are also introduced. In addition, several methods for the tail buffet alleviation of aircraft are summarized, and the merits and demerits of the methods are commented.
