摘　　要：本文通过大量故障原始资料总结了故障主要现象和共同特征。根据故障特点论述了主要研究途径,并通过大量的飞行试验、地面模拟试验和计算分析结果,讨论了产生飞机和直升机空中振荡的四类主要原因以及各种影响因素的分析。最后提出了预防原则和相应措施,并得出了一些有用的结论。In this paper, the main phenomena and common features are summarized through a lot of original failure data. By means of a lot of flight tests, ground simulation experiments and computation analyses, various research approaches are presented and four causes of the failure leading to the in-flight oscillation failure and analyses of various factors are summarized. Finally, some failure prevention principles and measures are proposed and useful conclusions are presented.
