摘要 行波圈是热声斯特林型发动机的一个主要的子系统 ,行波圈的基本属性对热声斯特林型发动机的整机稳定性和效率有着决定性的影响。单独对行波圈子系统的基本属性进行了理论和实验研究 ,通过改变回热器阻抗、平均压力和输入功率等控制参数 ,对单独行波圈环路内声场分布进行了详细研究 ,并且对有无谐振管情况进行了对比和分析。在理论上对行波圈的基本属性以及和谐振管的匹配进行了分析和讨论 。 The looped traveling wave thermoacoustic prime mover is the main sub system of thermoacoustic Stirling heat engine.The characteristics of this sub system influence the stability and the efficiency of the whole engine.To study the intrinsic of the looped sub system is important for the mach and the optimizing of the whole system.The sound field in the looped bube has been studied in the case of with resonator or without resonator.Some interesting phenomena are observed.Some useful conclusions are drawn from analysis.
