为了研究鸭蹼形状对划水推进性能的影响，建立了划水鸭蹼仿生推进模型。利用动网格技术对鸭蹼在水下划水的过程进行了研究，分析了菱形鸭蹼的水动力学性能并与三角形鸭蹼进行了对比。仿真结果表明，鸭蹼的推进是阻力推进和升力推进两个连续的推力产生过程，升力有利于推进，且菱形鸭蹼的推进性能优于三角形鸭蹼的推进性能。
為瞭研究鴨蹼形狀對劃水推進性能的影響，建立瞭劃水鴨蹼倣生推進模型。利用動網格技術對鴨蹼在水下劃水的過程進行瞭研究，分析瞭蔆形鴨蹼的水動力學性能併與三角形鴨蹼進行瞭對比。倣真結果錶明，鴨蹼的推進是阻力推進和升力推進兩箇連續的推力產生過程，升力有利于推進，且蔆形鴨蹼的推進性能優于三角形鴨蹼的推進性能。

In order to study the effect of duck flippers shape on swimming propulsion performance, the paddling duck web bionic propulsion model is established. The process of duck flippers swimming under water is studied by using the moving grid technology. Hydrodynamic performance of diamond duck webs is analyzed. And it is contrasted with that of the triangular flippers. The simulation results show that, the propulsion of duck flippers is two continuous thrust including process of drag and lift force propulsion. Lift force is conducive to advancing, and the propulsion performance of diamond flippers is better than that of the triangle duck flippers.
