摘要：

In this investigation, the authors studied the stability of steady flows in collapsible tubes of which static characteristics were theoretically calculated in the previous paper. The dynamics of the collapsible tube is approximately represented by a simplified lumped parameter model. On the basis of the model, the instability condition has been derived and the mechanism of the instability of the steady flow has been clarified. The instability region obtained theoretically is qualitatively in good agreement with the experimental results.
