本文围绕不同尺度级的输液管结构,针对液流引起的管道振动与稳定性综述了目前已有的几种物理和数学模型,详细介绍了梁模型输液管的各类振动控制方程,重点讨论了宏观尺度、微米尺度和纳米尺度下输液管振动方程的异同点.在此基础之上,进一步概述了近几年这些输液管振动与稳定性问题研究的现状和一些重要研究结果,其中也包括作者们近期的相关工作.最后对未来的研究趋势作了分析和预测.通过本文可以看到,输液管振动问题仍有不少难题尚未很好解决,特别是微纳米输液管的建模和流固耦振机理方面的研究亟需加强.
In this paper, we focus on the structure of the infusion tube at different scales, and present some existing physical and mathematical models for the vibration and stability of the pipeline caused by the liquid flow. The various vibration control equations of the infusion tube in the beam model are introduced in detail. Macro-scale, microscale and nanoscale transfusion tube vibration equation similarities and differences.On this basis, the current situation and some important research results on the vibration and stability of transfusion tubes in recent years are summarized, including the author The recent related work.Finally, the future research trends were analyzed and predicted.Through this paper we can see that there are still many problems in the transfusion tube vibration problems have not been solved, especially the micro-nano infusion tube modeling and fluid solid The research on the mechanism of coupling vibration urgently needs to be strengthened.
