摘要

提出了串列联动双圆柱流致摆振理念，构建了摆振运动方程，分析了受力与运动规律，建立了摆振试验装置，并基于室内试验探究了串列联动双圆柱流致摆振特性，研究旨在为流致振动发电设备设计提供参考。研究表明：串列联动双圆柱摆振响应表现为涡激振动规律；间距比对摆振振幅和锁定区间影响较大，间距比为4时振幅最小且响应中出现“再增长区”，间距比为6时振幅最大，间距比为8时锁定区间最大；系统刚度对摆振响应趋势影响不大，但不同刚度下摆振达到的最大振幅差异明显，该试验最大弧长比A*为0.98，出现在1400N/m刚度工况。

Abstract

The concept of tandem-linked double cylinders flow-induced rotation was put forward, the motion equation of rotational oscillation was constructed, and the law of force and motion was analyzed. An experiment device of rotational oscillation was established and explored the flow-induced rotation characteristics of tandem- linked double cylinders based on indoor experiments. The research aims to provide reference for the design of flow-induced vibration power generation equipment. The main conclusions are as follows: (1) The oscillation response of tandem-linked double cylinders presents the vortex-induced vibration (VIV); (2) The spacing ratio has a significant impact on the oscillation amplitude and “lock-in” interval. When the spacing ratio is 4, the amplitude is the smallest and the "re-growth region" appears in the response, when the spacing ratio is 6, the amplitude is the largest, and when the spacing ratio is 8, the lock-in interval is the largest. (3) The system stiffness has little effect on the rotational oscillation response trend, but the difference in the maximum amplitude reached with different stiffness is obvious. In this test, the maximum arc length ratio A* is 0.98, which occurs at the stiffness condition of 1400N/m.
