Passive and adaptive vibration suppression of pipes conveying fluid with variable velocity

Abstract

A passive and adaptive control method for stabilizing a pipe conveying fluid is presented. Owing to fluid–pipe interactions, pipes are subjected to excessive vibrations. Classical passive control methods are only valid for stabilizing the pipes over a narrow range of flow velocities. In this paper, the theory of nonlinear targeted energy transfer (TET) is applied to suppress the excessive vibration of a pipe by using an essentially nonlinear attachment, which is called a nonlinear energy sink (NES). Numerical evidence for a passive TET between the pipe and NES is proposed. Results show that the NES can robustly absorb and dissipate a major portion of the vibrational energy of the pipe.

A survey on modeling and control of thruster-assisted position mooring systems

“…A monopile-type wind turbine is selected as the example of the research. Monopile installation has been studied in Li et al (2014), Li, Acero, Gao & Moan (2016), Li, Gao & Moan (2016). Consider a scenario that the monopile foundation has been driven into the seabed, gravel and rock materials are placed on the seabed at the foundation location to protect the supporting structure against scouring.…”

Dynamics and Stability of Magnetically Actuated Pipes Conveying Fluid

“…Therefore, research in this area has been extensively carried out over the past several years. [2][3][4][5] The°uid-conveying pipe models may be classi¯ed into two groups: cantilevered and supported pipes. They are fundamentally di®erent and are treated separately.…”

The Analysis of Nonlinear Vibrations of Top-Tensioned Cantilever Pipes Conveying Pressurized Steady Two-Phase Flow under Thermal Loading

“…As highlighted by Païdoussis [8], the nonlinear problems of pipes conveying fluids cannot be resolved analytically, but recourse needs to be taken to adopt specialized analytical methods like perturbation techniques, numerical time difference methods, or a combined analytical-numerical method. The direct Lagrangian discretization method (Galerkin method) to convert the partial differential equations (PDEs) to ordinary differential equations (ODEs) and then resolve the resulting ODEs using numerical techniques has been adopted by some publications, namely, Modarres and Païdoussis [9], Wang et al [10], Sinir [11], Ritto et al [12], Chen et al [13], Tian-Zhi et al [14]. The usage of analytical methods like perturbation techniques is highly common with researchers working on nonlinear problems, such as Nayfeh [15], Nayfeh [16], Kesimli et al [17], and Oz and Boyaci [18], where the solutions were sought using an asymptotic expansion or by perturbing the original set of equations in terms of a small parameter which is either present in the equation or introduced artificially.…”
