Vibration analysis of viscoelastic damping material attached to a cylindrical pipe by added mass and added damping

Journal of Sound and Vibration, 2019
Abstract Vibration of pipes and cylindrical shells leading to noise and damage is an important engineering problem in plant systems and air conditioners, among others. To attenuate such vibration, a viscoelastic material is attached to pipes as a damping material.

Scaling of added mass and added damping of cylindrical rods by means of FSI simulations

Journal of Fluids and Structures, 2019
Abstract In this work, the effects of different working fluids on the dynamics of vibrating rods in fluid flows is investigated by means of Fluid–Structure Interaction (FSI) simulations. Different fluids with a wide range of density and viscosity are considered.

Evaluation of equivalent damping ratio of a structure with added dampers

Engineering Structures, 2004
The purpose of this study is to propose a new method for evaluating the equivalent damping ratio of a structure with supplemental damping devices to assess the vibration control effect quantitatively. The modal-energy-formed Lyapunov function is defined first, and the Riccati matrix and damping rate parameter are derived. Then from its analogy with the

Hydrodynamic Added Mass and Damping of the Kaplan Turbine

Volume 6: Fluids and Thermal Systems; Advances for Process Industries, Parts A and B, 2011
Kaplan turbine runner rotates in water flow inside an enclosed discharge ring. The vibratory runner motion in the fluid flow induces pressure forces onto the wet runner surfaces with inertia effects conveniently described by the so-called hydrodynamic added mass and damping. These inertia effects influence the wet natural frequencies and the amplitudes.
