摘要/Abstract

摘要：

颤振飞行试验是新型机种定型必不可少的环节,其目的是要确定颤振边界。由于颤振飞行试验的风险大、耗费高并且周期长,研究者一直在追求安全、准确和高效的颤振边界预测方法。鉴于此,在总结前人研究的基础上,从传统的颤振边界预测方法及其改进和新的颤振边界预测方法两个层面展开,对常用的和近年发展的颤振边界预测方法较为全面而相对简洁的论述,着重介绍了各种颤振边界预测方法的基本原理、适用性及其推广和改进。针对各种方法的原理和特点,将其归纳为构造稳定性参数的方法和基于流固耦合分析模型的方法,并对两类方法进行了对比和总结。最后,对目前颤振边界预测存在的一些技术难点及其发展趋势进行了初步的探讨。

Abstract:

Flight flutter testing, whose objective is to identify the flutter boundary, is an indispensible course for new aircraft to finalize. Because of the extremely great risk, high consumption and long period, researchers have been always pursuing a more secure, accurate and efficient flutter boundary prediction method. Based on the summary and analysis of the previous research, from the aspects of conventional flutter boundary prediction methods and new methods for flight flutter testing, this paper makes a more comprehensive and relatively concise introduction of many kinds of flutter prediction methods, and it highlights the basic principles, merits and demerits as well as the development of these methods. According to the fundamental principles and characteristics of various methods, they are divided into two categories, namely, introducing stability parameters methods and considering a coupled fluid-structure system method. Then, the two kinds of methods are compared and summarized. Finally, technical difficulties encountered at present and the development trend in the field of flight flutter testing are preliminary discussed.

Key words: flight flutter testing, flutter boundary prediction, aeroelasticity, basic principles, technical difficulties
