摘　　要：阐述了用等温分析法研究了热源温度、死区容积比、回热器有效性及热源温差和冷源温差等五个因子对斯特林发动机性能的影响。研究结果表明:发动机的性能随热源温度的增加而提高,热源温度越高,这种关系越弱;由于各种损失的存在,死区容积比有最佳值;回热器有效性是影响发动机性能的一个重要因子,提高回热器的有效性,是提高发动机性能的一个有效途径;相对热源温差,冷源温差对斯特林发动机的性能影响更大。研究结论为斯特林发动机的优化设计与节能运行提供了新的理论指导。The Isothermal analysis of Stirling engine was used in this paper, and five factors that affect the performance of Stirling engine are presented. The results indicate that when the temperature of hot source reaches some degree, again to improve the temperature will have little influence to the performance of Stirling engine ; because of the exist of energy losing, there is a best value of dead volume ratio;regenerator effectiveness has an important influence to Stirling engine, and improve the regenerator effectiveness is an efficiency way to improve the performance of Stirling engine;compared to hot source, temperature difference in cold source have bigger influence to the performance of Stirling engine. The results can provide guidance for the development of Stirling engine.
