“…In order to validate the correctness of the method in this paper, we simplify the FGM pipe to homogeneous pipe to calculate the natural frequencies and compare with the existing results. 25 After verifying the present method in this paper, the investigations are carried out to research the dynamic behaviors of a multi-span viscoelastic FGM pipe conveying fluid. For analysis convenience, several nondimensional quantities are defined as 19…”

In this paper, the dynamic behaviors of a multi-span viscoelastic functionally graded material pipe conveying fluid are investigated by dynamic stiffness method. The material properties of the functionally graded material pipe are considered as graded distribution along the thickness direction according to a power-law. Several numerical examples are performed to study the effects of volume fraction exponent, fluid velocity, internal pressure, and internal damping on the stability and frequency response of the fluid-conveying functionally graded material pipe. It's found that the viscoelastic functionally graded material pipe exhibits some special dynamic behaviors and it could increase the stability significantly when compared with the aluminum and steel pipes. The numerical results also demonstrate that by the introduction of the functionally graded material, the stiffness of the piping system could be modulated easily by designing the volume fraction function. Therefore, if the dominant frequency contents of the external loads are known, a preferable design of the functionally graded material pipe to reduce the vibration is possible.

“…The inside diameter of the cross section of the pipe is 0·19 m and outer diameter −0·20 m. The bending rigidity K of the steel pipe is 3001·008 KNm 2 . The values of the circular frequencies of the pipe are obtained for different values of the flow velocity as given Wu & Shin (2001). In figure 1, the first six of them are shown when the pipe is lying only on an Pasternak elastic foundation with a constant c 2 = 200 kNm/m.…”

The dynamic stiffness method and Transfer method is applied to study the vibration characteristics of the Euler-Bernoulli pipe conveying fluid in this paper. According to the dynamics equation of the pipe conveying fluid, the element dynamic stiffness is established. The vibration characteristic of the single-span pipe is analyzed under two kinds of boundary conditions. The results compared with the literature, which has a good consistency. Based on this method, natural frequency and the critical speed of the two types of multi-span pipe are deserved. This paper shows that the dynamic stiffness method and transfer matrix is an effective method to deal with the vibration problem of pipe conveying fluid.
