經本論文研究發現最佳防迴流阻風浪板取決於流過阻風浪板流量係數的高低與浪板之抵抗風壓能之應變能大小,其兩者因素互相需要妥協設計,故本論文分別以理論與實驗來證實PET聚酯薄膜材質厚度在0.1mm齒距在3.0mm有最佳之流量係數與應變能。 本論文重要結果分別為: (1)PET聚酯薄膜材質厚度0.1mm比0.188mm有較佳的流量係數。 (2)PET聚酯薄膜材質厚度在0.1mm齒距在3.0mm有最佳之流量係數。 (3)最佳設計優劣順序分別為新型設計間距3mm>新型設計間距5mm>新型設 計間距10mm>漸開型>新型設計間距20mm>螺旋型>噴嘴型。 (4)彈性阻風浪板其經濟性優於阻風門設計,故較具商用價值。 未來發展可以朝阻風門與浪板混合設計的方向考慮或者選用不同的彈性塑膠材料來測試,並朝更高流量係數更低風阻、低噪音之彈性浪板來設計。
The best defense of the thesis that resistance windsurfing back through resistance depends on the level of rough boards and corrugated flow coefficient of resistance to wind pressure to the size of the strain energy, which both need each other to compromise the design factors, this thesis are the theoretical and Experiments to confirm the PET polyester film thickness 3.0mm 0.1mm pitch the best of the discharge coefficient and strain energy。 Important results of this study are: (1) PET film thickness of 0.1mm better than 0.188mm flow coefficient。 (2) PET film thickness of 0.1mm pitch 3.0mm are the best in the flow coefficient。 (3)The best design for the new design were spacing 3mm > spacing 5mm > spacing 10mm > involute type > spacing 20mm > spiral type > nozzle type。 (4)Elastic resistance windsurfing choke the economy better than the design, so the more commercial value。 In the future development of hybrid design of the choke with the corrugated or choose a different direction to consider the flexibility of the plastic material to test, and lower flow coefficient towards higher wind resistance, low noise to the elastic wave board design.
