摘　　要：介绍了飞机抖振形成的机理及民用飞机振动和抖振相关适航审定要求。在该适航审定要求的指导下,给出了民用飞机抖振边界试飞方法:加速法、减速法和收敛转弯法。抖振包线包括等高度曲线、等最大使用校正空速(VMO)曲线、重心修正曲线、等重量曲线四部分,分别了给出各个部分曲线的绘制方法,并根据抖振边界试飞数据得出抖振包线图。该图可供民用飞机设计、试飞以及编制飞行手册参考使用。The reason of aircraft buffeting and relevant airworthiness approval requirements were introduced. Under the guidance of those airworthiness approval requirements, the methods of buffet boundary flight test were given, including accelerating, decelerating and wind-up turn. Buffet envelope includes equal flight altitudeline, equal Vmo line, correction CG line and equal weight line, the drawing methods of each part were proposed. Buffet envelop was calculated from lfight test data, which can be used for civil aircraft design, flight test and compiling manual.
