“…1), compared to only E 0 in classical viscoelastic water-hammer (N KV = 0), makes the pipe softer and results in a slower first mode of vibration. Viscoelasticity definitely smoothes the waterhammer transients caused by FSI by progressively eliminating higher frequencies of vibration (Rachid and Stuckenbruck, 1989;Achouyab and Bahrar, 2011).…”

“…Hachem and Schleiss (2011) modelled viscoelasticity and FSI to determine wave speeds in steel-lined rock-bored tunnels. Most recently, Achouyab and Bahrar (2011) published a numerical study on water hammer with FSI and viscoelasticity − similar to ours − in which the MOC-FEM approach was used to solve the equations. All cited simulations of water hammer in viscoelastic pipes did not consider the issue of support and elbow motion, something that can hardly be avoided in practice (Heinsbroek and Tijsseling, 1994;Tijsseling and Heinsbroek, 1999;Hambric et al, 2010).…”

“…Chung and Cheng optimized the pipe structure and added the vibration damping device, the lower-end boundary conditions are set as free end and fixed end, and the study shows that the dynamic response of the mining pipe caused by external excitation is weakened after the addition of the vibration damping device [8]. Achouyab and Bahrar used the FEM to analyze the pipe displacement offset under the fluid-solid coupling action [9]. e Korean scholar Hong et al used the concentrated mass method to analyze the three-dimensional dynamics of the deep sea mining pipe and obtained the mining pipe towing motion law [10].…”

In this paper, the 5000 m mining pipe is taken as the research object, and the transverse and longitudinal vibration laws of the pipe under different working conditions are analyzed. Based on the finite element method (FEM), the pipe is discretized and calculated by the Wilson-θ Wilson - θ integral method; finally, the corresponding vibration laws of the mining pipe are obtained. The research shows that the mining pipe vibration responses are irregular motion, with the obvious oscillation phenomenon, and the overall vibration trend decreases first and then increases from the top to the bottom; the maximum vibration response occurs at the pipe top. Under the same working conditions, increasing the towing velocity will decrease the overall longitudinal vibration amplitude and increase the overall transverse vibration amplitude. While the ore bin weight will increase the longitudinal vibration amplitude and decrease the transverse vibration amplitude, increasing the mining pipe large diameter stepped section length and damping will decrease the longitudinal and transverse vibration simultaneously. When the towing velocity is between 0–2.8 m/s, the longitudinal vibration intensity is large, which is the main vibration mode. When the towing velocity is 2.8 m/s, the critical point is reached, and the longitudinal and transverse vibrations have the same intensity. When the towing velocity is greater than 2.8 m/s, the transverse vibration intensity is gradually greater than the longitudinal vibration intensity; at this time, the control of the transverse vibration should be appropriately increased.

“…Chung concentrated on the mechanical properties of the three-dimensional nonlinear, axial bending, and torsional coupling of the mining pipe [8]. Achouyab and Bahrar simplified the pipe into a plane beam and used Newmark algorithm to calculate the pipe transverse displacement [9]. Japanese research scholar Aso used the analytical method to study the dynamic characteristics of equal-diameter mining pipe under the variable speed towing conditions [10].…”

This paper aimed to study the longitudinal vibration characteristics of the 5000 m mining pipe in the ocean under different working wind conditions, offset angle, damping, and ore bin weight. Based on the finite element method, the mining pipe is simplified into beam element and discretized, and the physical and mathematical models of the mining pipe system are established. The Wilson-θ direct integral method is adopted for numerical calculation. The results show that the longitudinal vibration of the mining pipe is irregular, which presents the phenomenon of oscillation. The vibration amplitude decreases first and then increases from top to bottom, the minimum vibration amplitude appears at 1000 m, and the maximum vibration amplitude appears at the top of the mining pipe. Under the same working wind condition, the overall longitudinal vibration amplitude of the mining pipe can be increased by increasing the ore bin weight and the offset angle, but neither of them can change the frequency of the longitudinal vibration. The closer the excitation frequency generated by different working wind conditions is to the natural frequency, the larger the mining pipe longitudinal vibration amplitude is. The closer the vibration frequency generated by the same excitation frequency is to the natural frequency, the stronger the vibration intensity is, and when damping is added, the vibration intensity decreases faster.
