摘　　要：涉及的气动分置式斯特林制冷机没有气动腔,依靠蓄冷器两端的压差提供推移活塞运动推力,目前还没有人对这种气动膨胀机的位移进行过测试和研究。建立了数学模型对推移活塞进行受力分析,并给出其运动方程及其求解方法。最后,用实验测量数据对其进行验证。The pneumatically driven split stifling cryocooler has no pneumatic cavity. The force driving the displacer is offered by the press drop of the regenerater. To the date, nobody has measured the displacement of this kind of pneumatically driven split stifling cryoeooler, and neither researched it. This paper builds math model and analyzes the pressed condition of the displacer, and gives movement equation and also the solution. Finally, it provides experimental datas to testify the calculation.
