单片蹼的水动力性能试验研究

Experiment of Hydrodynamic Performance of Monofin

在蹼泳比赛项目中 ,新型三维立体外形的脚蹼的推进性能明显优于以前的平脚蹼 ,为了说明此问题 ,文中选取两个新型冠军蹼原型和一个平板冠军蹼原型为试验对象 ,对每一个蹼进行了不同水速、不同摆频和不同摆幅的系列比较试验 ,记录了蹼运动过程中三个自由度的力和力矩及蹼的角位移随时间变化的数据和曲线 .通过对试验曲线的重复性和稳定性的分析 ,证实了新型三维立体外形脚蹼的推进性能的优越性 .

In the fin swimming event,the contour of the new type monofin is of three dimensionals,and its propulsicve performance is superior to the previous flat monofin.Experiment researches are completed for the hydrodynamic performance of three champion monofins' prototypes,two of them are of three dimensionals,and one is of flat.Varying the flow velocity,changing frequency,amplitude and radius of the fin,a series of experiments are preceded in the circulating channel of Wuhan University of Technology, and a number of data and curves are recorded for three degree hydrodynamic displacement of the fins.Through analysing the repeated feature of stability of the experiment data,it proves the monofin to be successful in push capacity.
