摘要：建立斯特林发动机的绝热分析模型并介绍其数值求解方法。分析了该模型下的计算结果获得不同运行参数（充气压力和运行频率）、回热器容积和回热器平均温度对系统性能的影响。结果表明，增大充气压力及运行频率有助于提高系统的输出功率；对于孔隙率一定的回热器而言，从轴向增大其容积会使输出功率降低；另外，回热器平均温度降低会使膨胀腔及压缩腔温度波动更为剧烈。研究结果能够对提高斯特林发动机系统的性能提供一定指导及帮助。

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.
