| Abstract: | In order to demonstrate the vibration and stability character errected by the fluid dynamic pressure and velocity of the pipe line containing flowing fluid, the convenentional differential equations are given in detail in this paper.It is pointed out that, when the flowing fluid velocity is equal or the integral number time of the critical velocity, the pipe may be occurred lose stability; and it is also indicated that the larger density of fluid will make the lower natural frequency and critical velocity.Finally, a caculation example is given for demonstrating the flow chart vibration and stability of the pipe line containing flowing fluid, and a computable is also given in this paper. |
