摘要：建立斯特林發(fā)動機的絕熱分析模型并介紹其數值求解方法。分析了該模型下的計算結果獲得不同運行參數（充氣壓力和運行頻率）、回熱器容積和回熱器平均溫度對系統(tǒng)性能的影響。結果表明，增大充氣壓力及運行頻率有助于提高系統(tǒng)的輸出功率；對于孔隙率一定的回熱器而言，從軸向增大其容積會使輸出功率降低；另外，回熱器平均溫度降低會使膨脹腔及壓縮腔溫度波動更為劇烈。研究結果能夠對提高斯特林發(fā)動機系統(tǒng)的性能提供一定指導及幫助。

Abstract：The adiabatic model of Stirling engine was built and its simulation solution method was introduced. The study analysed the effect to the Stirling engine performance of different operation parameters（the charge pressure and the operating frequency），regenerator volume and regenerator average temperature and the results were discussed. It is showed that increasing the charge pressure and operating frequency contributes to the enhancement of output power. Otherwise，increasing the volume of regenerator in axial direction which the porosity is a constant would decrease the output power. Moreover，reducing the average temperature of regenerator would lead to the more violent fluctuate of temperature of the expansion and compression space. The study could provide some guidance for the optimization of Stirling engine performance.

Key words： stirling engine    adiabatic model    operation parameter    regenerator
