| dc.description.abstract | 本研究整合連桿機構作動原理與傳統的往復式發電機之設計概念，將連桿與對稱型機翼做一結合，嘗試設計出不需控制系統、或降低控制系統耗電量的連桿機構往復式發電機，並且對於發電機運作特性與性能，作一系列的討論。
首先，對於傳統的往復式發電機做運作原理的探究，接著探討連桿機構的作動原理與限制，並利用對稱型機翼結合四連桿之運動軌跡，計算其在流體中之受力，並且證明在單一對稱型機翼之下，四連桿式發電機無法藉由所受之流體力完成往復式擺盪。 接著設計出一四連桿加裝襟翼往復式發電機，並做進一步的空氣動力學討論，利用二維的計算流體力學模擬計算四連桿加裝襟翼往復式發電機在流體中的表現，藉以了解其工作特性，並將其結果與傳統控制策略的往復式發電機比較，證明在主機翼加裝可控俯仰角之襟翼後，可達往復式擺盪之目的。 再者，利用不同幾何機翼的受力與受力矩特性，結合連桿機動學原理，設計出一不需控制系統的五連桿滑桿式發電機，並且探討影響此機構工作特性的各種機構與流場參數，最後利用流體力學原理，計算受力與受力矩，並且將其結果與傳統的往復式發電機比較，嘗試找出在不需控制系統之前提下，所需考量設計中之參數。 | zh_TW |
| dc.description.abstract | The research is to combine a linkage and a symmetry hydrofoil, which is integrated with field of mechanism and classical oscillating hydrofoil. The purpose of this study is to design a electricity generator which can continue oscillating without control systems on hydrofoils, or makes the electric power consumption lower. Under the research, we discuss the performance and the dynamic behavior of the electricity generator.
First, we discuss the fundamental principle and mechanism of classical oscillating hydrofoil. And design a generator which combines a four-bar linkage and a symmetry hydrofoil, try to calculate the state of force on hydrofoil in the fluid field. Finally, proving that a generator which combines a four-bar linkage and a symmetry hydrofoil cannot oscillate continuously by a symmetry hydrofoil without flip. Moreover, design a generator which combines a four-bar linkage and a symmetry hydrofoil with flip. Calculate the state of force on generator using two-dimensional computational fluid dynamics. Finally, find out the result and compare with the classical oscillating hydrofoil, proving that a generator which combines a four-bar linkage and a symmetry hydrofoil with flip can oscillate continuously. Furthermore, base on the theory of mechanism, using the state of force and torque, to design a generator which combines a five-bar linkage with a slider and a symmetry hydrofoil, and to discuss the mechanism characteristic which affects by different parameters in the fluid field. Finally, base on the theory of fluid dynamics, calculate the state of force and torque, find out the result and compare with the classical oscillating hydrofoil, try to find out the parameters of the design without control systems on hydrofoil. | en |
