摘要 首先介绍了舵面振荡问题产生的背景、适航的要求以及常规的振荡载荷分析方法;然后基于工程实践中的经验和研究,探讨了常规分析方法中存在的一些缺陷,提出了针对这些缺陷的解决途径,作为对常规分析方法的发展和完善。 Control surface oscillation failure is a common and serious failure case on modern fly-by-wire aircraft,it is a resonance problem in nature.This paper introduces the background of oscillation failure,the requirements of airworthiness and the conventional oscillation loads analysis method.Based on the experience and research in engineering practice,it discusses some defects of the conventional analysis methods,and puts forward some solutions to these defects as the development and improvement of the conventional analysis methods.
