本文建立了研究粘弹性可瘪管脉动流位移振荡的实验和理论模型，归结出了管壁位移振荡的控制方程，并应用摄动方法求出问题的摄动解。文章最后还给出了粘弹可瘪管位移振荡发生的判别准则和三种不同流动状态区域，并讨论了来流速度和管壁粘性等参数对这些区域的影响情况。
In this paper, the experimental and theoretical model for the study of viscoelastic deflagration tube pulsating flow displacement oscillation is established. The governing equations of tube wall displacement oscillation are summarized. The perturbation method is used to find the perturbation solution of the problem. At the end of the article, the criteria for determining the viscous-viscous deflagration tube displacement and the three different flow regimes are also given. The influences of the flow velocity and the viscosity of the tube wall on these regions are also discussed.
