摘　　要：基于斯特林绝热模型对α型斯特林热机运行状况进行数值模拟,通过对热机各部件间的质量与功量传输的计算,模拟振荡流体对热机运行的影响。同时在不同工况下探讨斯特林热机膨胀腔与压缩腔的容积比对热机效率的影响,获得最大热效率,为斯特林热机的优化设计提供思路。The operating status of an α type Stirling engine was simulated based on the Stirling adiabatic model. By calculating the mass and work transferred between every adjacent part of the engine, the influence of the oscillating fluid on the engine was simulated. Meanwhile, the effect of the volume ratio of the expansion chamber and compression chamber in different working status on the efficiency of the engine was discussed to obtain the maximum thermal efficiency theoretically as well as provide new ideas for optimization of the Stirling engine.
