An Investigation into the Dynamic Interaction Between an Electro-dynamic Shaker and a Test Structure with Cubic Nonlinearity
(Springer, 2015-01-01)
This chapter describes the dynamic behaviour of a coupled system where a nonlinear oscillator is attached and driven harmonically by an electro-dynamic shaker. The shaker is modelled as a linear single degree-of-freedom ...
Nonlinear dynamics of a flexible portal frame under support excitation
(2012-12-01)
This paper presents a nonlinear dynamic analysis of a flexible portal frame subjected to support excitation, which is provided by an electro-dynamical shaker. The problem is reduced to a mathematical model of four degrees ...

Some features of the acceleration impulse response function
(2021-01-01)
Impulse response functions (IRFs) and frequency response functions (FRFs) are fundamental quantities that describe the dynamic behaviour of a linear vibrating system in the time and frequency domains respectively. The ...
Using passive control by a pendulum in a portal frame platform with piezoelectric energy harvesting
(Sage Publications Ltd, 2018-08-01)
This work presents a passive control strategy using a pendulum on a simple portal frame structure, with two-to-one internal resonance, with a piezoelectric material coupling as a means of energy harvesting. In addition, ...
Mathematical model and dynamic analysis of pendulum system excitation via an electro-dynamical shaker
(2020-01-01)
In this paper, we present a mathematical model and numerical investigations of a pendulum system excited by an EDS (Electro-Dynamical Shaker). The dynamic analysis is considered by history of the time, phase plane, Poincaré ...
