Partition plate type cylindrical component vortex-induced vibration suppression device
The invention provides a partition plate type cylindrical component vortex-induced vibration suppression device. The partition plate type cylindrical component vortex-induced vibration suppression device sleeves a cylindrical component and comprises two rolling mechanisms and a partition plate. The two rolling mechanisms sleeve the cylindrical component, and the inner surfaces and the outer surfaces of the rolling mechanisms can relatively rotate. The upper end and the lower end of one side of the partition plate are fixedly connected between the two rolling mechanisms. The partition plate candisturb the regular falling movement of vortexes and suppress the vortex-induced vibration of the cylindrical component. On the basis of the basic principle of changing the aerodynamic configurationof an object, the partition plate type cylindrical component vortex-induced vibration suppression device disturbs the regular falling movement of the vortexes, suppresses the vortex-induced vibrationof the cylindrical component, and is clear in principle and high in practicability.
本发明提供了一种隔板式圆柱形构件涡激振动抑制装置，所述涡激振动抑制装置套在圆柱形构件外，包括：2个滚动机构和分隔板；所述2个滚动机构套在所述圆柱形构件上，且所述滚动机构的内表面和外表面可以相对转动；所述分隔板的一侧的上下两端固定连接在所述2个滚动机构之间；所述分隔板可以扰乱旋涡的规则脱落，抑制圆柱形构件的涡激振动。本发明装置基于改变物体气动外形的基本原理，扰乱旋涡的规则脱落，抑制圆柱形构件的涡激振动，原理清晰，实用性强。
