| Abstract: | 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. |
