海洋立管涡激振动实验设计

Experimental Design of Vortex-induced Vibration of Marine Riser

设计了海洋立管涡激振动实验。首先设计单立管涡激振动实验,通过实验,学生可掌握应变片半桥设计的基本知识,波流联合水槽及数据采集仪的工作原理和使用方法,学会立管涡激振动的测试方法,并且对涡激振动的理论知识进行巩固和强化。在此基础上拓展进行立管群涡激振动实验及涡激振动抑制实验,分析立管间距以及不同抑振装置对涡激振动的影响,增强了学生应用所学知识发现问题、分析问题和解决问题的实践创新能力,从而达到提高教学质量的目的。

An innovation experiment of vortex-induced vibration of marine riser was designed according to the requirements of new engineering talent training,and with the goal of improving students'practical ability and innovative ability.Firstly,the experimental study of vortex-induced vibration of single riser was carried out,through this experiment,students can obtain the basic knowledge of the method of half-bridge,the operational principle and usage of wave-current flume and data acquisition instrument,thus the theoretical knowledge of vortex-induced vibration is consolidated and the test method of vortex-induced vibration of riser is mastered.On this basis,according to the international research hotspots,the vortex-induced vibration experiment and vortex-induced vibration suppression experiment of riser group were carried out,the influence of the spacing and the different suppression equipments on the vortex-induced vibration was analyzed,which enhances the practical innovation ability of students to find problems,analyze problems and solve problems by using the knowledge they have learned,and achieves the purpose of improving the teaching quality.
