圆柱涡激振动研究进展与展望

Progress and Prospect of the Study on Vortex-Induced Vibration of Circular Cylinders

圆柱涡激振动广泛存在于机械工程、海洋工程等诸多领域,研究者们取得了许多研究成果,而系统综述圆柱涡激振动的论文距今已近10 a,因此,有必要对近10 a的研究进展进行系统分析。文中系统地总结了近10 a圆柱涡激振动研究成果,阐述了圆柱涡激振动的尾流模态和其对应的响应分支之间的因果关系,分析了影响圆柱涡激振动的关键因素(如质量比、阻尼比和雷诺数)对涡激振动响应的影响,介绍了圆柱涡激振动最大响应振幅的曲线拟合公式及其局限性,最后对圆柱涡激振动的研究方向提出建议。

Vortex-induced vibration（VIV） of circular cylinders exists in many fields, including mechanical engineering and marine engineering. Many new research results have been obtained by many researchers in the last decade. The latest review of VIV was published nearly ten years ago. Therefore, it is necessary to conduct a detailed review on the research progress achieved during the last decade. This paper systematically summarizes the research findings on VIV of circular cylinders in the last decade, expounds the causality between the wake modes and their corresponding response branches, and analyzes the effects of the key factors on the VIV responses,such as the mass ratio, damping ratio and Reynolds number. After discussing the curve fitting formula of the maximum amplitude of VIV responses and its limitations, some suggestions are presented on the direction of future research on VIV of circular cylinders.
