This study utilised positive Lyapunov exponents’ criteria to develop chaos diagram on the parameters space of 4-dimensional harmonically excited vibration absorber control Duffing’s Oscillator. Relevant simulations were effected by choice combination of constant step Runge-Kutta methods and Grahm Schmidt Orthogonal rules. Simulations of 4-dimensional hyper-chaotic models of modified Lorenz and ...

Dynamic vibration absorber (DVA) integrated with a piezoelectric stack energy harvesting subjected to base excitation is introduced in this paper. The system of dynamic and (DVA-PSEH) has two functions, the first reduce vibrations for primary system, second convert part vibrational into electricity through effect. mechanical electrical responses electromechanical are determined by complex ampli...

Linear passive vibration absorbers, such as tuned mass dampers, often contain springs, dampers and masses, although recently there has been a growing trend to employ or supplement the mass elements with inerters. When considering possible configurations with these elements broadly, two approaches are normally used: one structure-based and one immittance-based. Both approaches have their advanta...

This paper presents the design of an experimental electromechanical device for vibration control and energy harvesting. Traditionally, when the broadband resonant response due to a selected mode of a lightly damped structure needs to be controlled a vibration absorber is used. The resonance frequency of the absorber can be chosen to minimise the response of the structure under control. Optimisi...

The paper investigates a nonlinear vibration mitigation strategy of variable length pendulum subjected to harmonic external excitation. A absorber in form tri-pendulum system is used reduce the response primary pendulum. Thus, non-stationary problem using another passive absorber. Due genuine interest capturing dynamic interaction, numerically studies performance mass and absorber, first, by co...

To address the contradiction between ride comfort and handling stability, a new vibration-absorbing wheel structure with time-delay feedback control was proposed by applying feedback-controlled dynamic vibration absorber to structure. Using H2 optimization particle swarm algorithm (PSO), design parameters of were obtained sprung mass acceleration (SMA), suspension deflection (SD) tire (DTD) as ...
