Optimal Design of Damped Dynamic Vibration Absorber for Damped Primary Systems
This study focuses on the optimum design of the damped dynamic vibration absorber (DVA) for damped primary systems. Different from the conventional way, the DVA damper is connected between the absorber mass and the ground. Two numerical approaches are employed. The first approach solves a set of nonlinear equations established by the Chebyshev’s equioscillation theorem. The second approach mini...
متن کاملDesign optimization of a damped hybrid vibration absorber
In this article, the H∞ optimization design of a hybrid vibration absorber (HVA), including both passive and active elements, for the minimization of the resonant vibration amplitude of a single degree-of-freedom (SDOF) vibrating structure is derived by using the fixed-points theory. The optimum tuning parameters are the feedback gain, the tuning frequency, damping and mass ratios of the absorb...
متن کاملDynamical stability of cantilevered pipe conveying fluid in the presence of linear dynamic vibration absorber
When the velocity of fluid flow in a cantilevered pipe is successively increased, the system may become unstable and flutter instability would occur at a critical flow velocity. This paper is concerned with exploring the dynamical stability of a cantilevered fluid-conveying pipe with an additional linear dynamic vibration absorber (DVA) attachment. It is endeavoured to show that the stability o...
متن کاملAn Overview of Disarray in Vibration Analysis of Undamped Dynamic Vibration Absorber
There are numerous sources of vibration in an industrial environment: in processes such as pile driving and blasting; rotating and reciprocating machinery such as engines, Compressors, and motors; transportation vehicles such as trucks, train and aircraft; the flow of fluids; and many others. Vibration absorption is a method of adding a tuned spring-mass absorber to a system to create anti-reso...
متن کاملAn Application of Chebyshev’s Min-max Criterion to the Optimal Design of a Damped Dynamic Vibration Absorber
Watts [1] in 1883 and Frahm [2] in 1909 reported on the first use of a dynamic vibration absorber. The range of industrial applications of such device is wide and includes the minimization of the rolling of ships, the damping of torsional vibration of internal combustion engines and the smoothing of vibrations in a barber cutter. The minimization of oscillations of tall buildings by means of dy...
