摘　　要：建立了 80 K分置式斯特林制冷机连接软管的理论模型 ,通过对控制方程进行处理及合理简化 ,对边界条件的处理引入特征线法 ,通过数值计算对控制方程进行了求解 ,通过实验对理论模拟结果进行了验证 ,证明了本模拟方法具有良好的准确性。In this paper, a theoretical model and its controlling equations are set up for the connecting hose of an 80K split-Stirling cycle cryocooler. By introducing the method of characteristics, the inlet (outlet) conditions were dealt and the governing equations are solved by numerical method. The simulated results are compared with the experimental one, and they are in good agreement.
