自由活塞型史特林引擎之理論分析和實驗驗證

本文以理論分析自由活塞型史特林引擎，並且製作質驗用自由活塞型史特林引擎驗證相關結論。計算結果顯示，動力活塞之振動和移氣胴體之振動，兩者須發生共振，因爲當受迫振動的移氣胴體之頻率，與動力活塞振動的頻率相近時，移氣胴體之振動具有領先動力活塞90℃之相位差，使工作流體能進行熱機循環，把各種能源的熱能轉換成動能。

A theoretical analysis for free piston type Stirling engines has been carried out and the results of the analysis have be verified by using a free piston type stirlng engine made in the lab. The results of the analysis reveal that the resonance between the power piston and the displacer piston is vital for operating free piston type Stirling engine. Because when the angular frequency of idealized simple harmonic oscillation of the displacer piston is similar to that of power piston, the phase of simple harmonic oscillation of the displacer along with the displacer piston lead 90℃ than that of the power piston. Therefore, the working fluid inside the free piston type Stirling engine fulfills the so called heat engine cycle and the heat produced by various energy resource is transferred into kinetic energy through the engine.
