Application of linear and nonlinear vibration absorbers for the nonlinear beam under moving load
Recently, a large amount of studies have been related to nonlinear systems with multi-degrees of freedom as well as continuous systems. The purpose of this paper is to optimize passive vibration absorbers in linear and nonlinear states for an Euler-Bernoulli beam with a nonlinear vibratory behavior under concentrated moving load. The goal parameter in the optimization is maximum deflection of t...
متن کاملDraft: a Principle of Similarity for Nonlinear Vibration Absorbers
With continual interest in expanding the performance envelope of engineering systems, nonlinear components are increasingly utilized in real-world applications. This causes the failure of wellestablished techniques to mitigate resonant vibrations. In particular, this holds for the linear tuned vibration absorber (LTVA), which requires an accurate tuning of its natural frequency to the resonant ...
متن کاملNonlinear Optimal Control Techniques for Vibration Attenuation Using Magnetostrictive Actuators
This paper addresses the development of a nonlinear control design for attenuating structural vibrations using magnetostrictive transducers operating in nonlinear and highly hysteretic operating regimes. We consider as a prototype a thin plate subjected to exogenous pressure waves and controlled via Terfenol-D transducers at the plate edges; however the methodology is sufficiently general to en...
متن کاملOrder-Tuned Vibration Absorbers for a Rotating Flexible Structure with Cyclic Symmetry
This paper investigates the use of order-tuned absorbers to attenuate vibrations of flexible blades in a bladed disk assembly subjected to engine order excitation. The blades are modeled by a cyclic chain of N oscillators, and a single vibration absorber is fitted to each blade. These absorbers exploit the centrifugal field arising from rotation so that they are tuned to a given order of rotati...
متن کاملdesign and performance evaluation of tuned vibration absorber for the vibration control of a centrifugal pump
with the prolonged use of domestic centrifugal pump, due to erosion, corrosion and an unbalance the sever vibration of the pump are resulted. an erratic sound coming out of pump makes the user uncomfortable. here, tuned vibration absorber (tva) is used as a vibration controlling device. it is designed to reduce the rms velocity below 20% of the circumferential speed, at which the impeller is ba...
