中文摘要 本研究以開發新型自由活塞式史特靈引擎為目標,為達成起動迅速與提高振動頻率的目的,利用彈簧將移氣器及動力活塞作連接,並自行設計製作平面彈簧,完成新型自由活塞式史特靈引擎原型機之實作。此外,研究中亦同步發展理論模式,將動力模式及熱力模式整合,其中動力模式使用雙自由度運動方程式來描述引擎中之移氣器與動力活塞之運動狀態;熱力模式則將引擎內部分成三個控制體積(膨脹室、再生通道以及壓縮室)來進行分析。利用理論模式可探討加熱溫度、移氣器中央軸外徑、動力活塞質量、移氣器彈簧常數及動力活塞彈簧常數等重要參數對引擎運動行為與引擎功率之影響。最後,將理論模式之預測結果與所製作之自由活塞式史特靈引擎實測數據相互驗證。針對基準組參數進行理論分析,可得其振動頻率為30.5 Hz,此與相同基準組參數下之實驗之頻率30.2 Hz頗為接近。
英文摘要 The major purpose of this study is to develop a novel Free-Piston Stirling engine, which is able to achieve quick starting from rest at high oscillation frequency, by connecting the displacer to the piston with a spring. A prototype engine has been designed, manufactured and assembled successfully for experiments. In the mean times, theoretical modeling integrating a dynamic and a thermodynamic models has been performed for numerical predictions of the performance of the engine. The dynamic model involves two equations of motions which govern the kinematic behaviors of both the displacer and the piston. On the other hand, in the thermodynamic model, the engine is divided into three chambers (expansion chamber, regenerative channels, and compression chamber) and effects on engine performance of key parameters, such as heating temperature, diameter of central shaft of the displacer, mass of the piston, displacer spring constant, and piston spring constant, are evaluated. The predictions by the theoretical model are further confirmed by the experiments. For example, for the base-line case, the numerical prediction of the oscillation frequency by the theoretical model is approximately 30.5 Hz, which is close to the experimental reading of 30.2 Hz.
