Stability and parametric resonances of a pipe conveying pulsating fluid

研究了两端铰支输流管道在脉动内流作用下的参数共振问题。用常规分析方法导出了三种参数共振区域的边界曲线方程 ,并据此讨论了阻尼、平均流速、质量比、重力系数、预紧力。

This paper deals with the stability and parametric resonances of a pinned-pinned pipe conveying pulsating fluid. The criterion of stability of the pipe is derived with relatively simple analytical method. According to the criterion the effect of the physical parameters of system, such as the damping, velocity, ratio of masses, coefficient of gravity and force of compression, on the regions of the three parametric resonances has been discussed.
