An analogue twin for piezoelectric vibration damping of multiple nonlinear resonances

A broadband controller for shunt piezoelectric damping of structural vibration

Abstract In this paper a broadband active shunt technique for controlling vibration in piezoelectric laminated structures is proposed. The effect of the negative capacitance controller is studied theoretically and then validated experimentally on a piezoelectric laminated simply supported plate. The ‘negative capacitance controller’ is similar in nature to passive shunt damping techniques, as a...

Nonlinear Vibration Analysis of Piezoelectric Functionally Graded Porous Timoshenko Beams

In this paper, nonlinear vibration analysis of functionally graded piezoelectric (FGP) beam with porosities material is investigated based on the Timoshenko beam theory. Material properties of FG porous beam are described according to the rule of mixture which modified to approximate material properties with porosity phases. The Ritz method is used to obtain the governing equation which is then...

Results for Twin Singular Nonlinear Problems with Damping Term

The study ofmultipoint boundary value problem for linear second-order ordinary differential equation was initiated by I1’in and Moiseev 1 motivated by the work of Bitsadze and Samarskiı̆ 2–4 on nonlocal linear elliptic boundary value problem, which is a new area of still fairly theoretical exploration inmathematics. Several authors have expounded on various aspects of this theory; see the survey...

Vibration Analysis of a Nonlinear System with a Nonlinear Absorber under the Primary and Super-harmonic Resonances (TECHNICAL NOTE)

Abstract   In vibratory systems, linear and nonlinear vibration absorbers can be used to suppress the primary and super-harmonic resonance responses. In this paper, the behavior of a nonlinear system with a nonlinear absorber, under the primary and super-harmonic resonances is investigated. The stiffnesses of the main system and the absorber are cubically nonlinear and the dampers are linear. M...
