中文摘要：
颤振一类气动弹性稳定性问题是叶轮机械设计者关心的主要问题之一.本文对叶轮机械叶片颤振模型研究的进展进行了回顾,包括非定常气动模型、结构模型以及颤振的预测方法等内容.通过对颤振模型研究的介绍,讨论了不同方法处理颤振这类气动弹性稳定性问题的优缺点.提出了关于颤振研究目前的不足和部分难点,认为流固耦合模型的研究值得进一步重点关注.
英文摘要：
Aeroelastic stability in the form of blade flutter is a major concern for designers in the field of turbomachinery. This paper presents a review of the research and development on blade flutter modeling, including the unsteady aerodynamic model, the structural model and flutter prediction methods. Based on the presentation of these models, the fundamental mechanism and effects of different treatments are discussed. At the end of paper, some deficiencies in the research of flutter and difficulties in modeling fluid-solid coupling effects are pointed out, to which attention should be paid in future.
