This paper proposes a novel method to increase the power output of a cantilever beam-based electromagnetic vibration energy harvester through anti-phase resonance. A new cantilever beam design is presented to achieve this. By introducing an anti-phase motion between the coil and the magnets at resonance under the same base excitation input, the relative velocity of the coil cutting through the magnetic...

Pendulum energy converter excited by random loads

ZAMM ‐ Journal of Applied Mathematics and Mechanics / Zeitschrift für... > 98 > 3 > 349 - 366

We present new solutions for the dynamics of a pendulum energy converter which is vertically excited at its suspension point. Thereby, we deal with a random excitation by a non‐white Gaussian stochastic process. We formulate the pendulum energy converter as a weakly perturbed Hamiltonian system. The random process across the energy levels of the Hamiltonian system is then approximated by a Markov...

Parametric pendulum based wave energy converter

Daniil Yurchenko, Panagiotis Alevras

Mechanical Systems and Signal Processing > 2018 > 99 > C > 504-515

The paper investigates the dynamics of a novel wave energy converter based on the parametrically excited pendulum. The herein developed concept of the parametric pendulum allows reducing the influence of the gravity force thereby significantly improving the device performance at a regular sea state, which could not be achieved in the earlier proposed original point-absorber design. The suggested design...

Procedia Engineering > 2017 > 199 > C > 1086-1091

The paper proposes a method to investigate the stochastic dynamics of a vibroimpact single-degree-of-freedom fractional system under a Gaussian white noise input. It is assumed that the system has a hard type impact against a one-sided motionless barrier, which is located at the system’s equilibrium position; furthermore, the system under study is endowed with an element modeled with fractional derivative...

On enhancement of vibration-based energy harvesting by a random parametric excitation

Roman V. Bobryk, Daniil Yurchenko

Journal of Sound and Vibration > 2016 > 366 > C > 407-417

An electromechanical linear oscillator with a random ambient excitation and telegraphic noise parametric excitation is considered as an energy harvester model. It is shown that a parametric colored excitation can have a dramatic effect on the enhancement of the energy harvesting. A close relation with mean-square stability of the oscillator is established. Four sources of the ambient excitation are...

Dynamics of a parametric rotating pendulum under a realistic wave profile

Tatiana Andreeva, Panagiotis Alevras, Arvid Naess, Daniil Yurchenko

International Journal of Dynamics and Control > 2016 > 4 > 2 > 233-238

Stochastic dynamics of a rotating pendulum is investigated upon the development of a novel wave energy converter. A dependency of the pendulum’s rotational potential on the wave profile is studied. The latter is modeled using a non-harmonic periodic function with a sharp or bent crest. It has been shown that the sharp wave profile significantly deteriorates the rotational potential of the parametric...

Experimental investigation of a rotating parametric pendulum

Nonlinear Dynamics > 2015 > 81 > 1-2 > 201-213

The parametrically excited pendulum has been attracting significant interest with recently being involved in the development of a wave energy converter. The capability of establishing rotational motion is however restricted by the quite low frequency of ocean waves. Introducing a design of a tri-pendulum instead of a simple pendulum could provide a solution to that obstacle. In this paper, an experimental...

Stochastic synchronization of rotating parametric pendulums

Panagiotis Alevras, Daniil Yurchenko, Arvid Naess

Meccanica > 2014 > 49 > 8 > 1945-1954

In this paper synchronization of two pendulums mounted on a mutual elastic single degree-of-freedom base is examined. The response of the pendulums is considered when their base is externally excited by a random phase sinusoidal force, thus leading to stochastic parametric excitation of the pendulums. The target is for the pendulums to establish and preserve rotary response since this study is motivated...

Stochastic Dynamics of a Parametrically base Excited Rotating Pendulum

Daniil Yurchenko, Panagiotis Alevras

Procedia IUTAM > 2013 > 6 > Complete > 160-168

This paper studies the rotational motion of a parametrically excited pendulum, dynamics of which is governed by a stochastic nonlinear Mathieu equation. The interest to this problem is based on the fact that this motion may be used to harness wave energy, capturing the heaving motion of waves. Thus a narrow band excitation is used, which is modeled as a harmonic process with random phase modulations...

Noise-induced suppression of resonant vibrations

Roman V. Bobryk, Daniil Yurchenko

International Journal of Dynamics and Control > 2013 > 1 > 4 > 277-282

The effect of random parametric noises on reduction of a resonant amplitude of forced linear SDOF systems is explored. It is found that noise-induced excitations of the stiffness coefficient of the system can substantially reduce the amplitude of resonant vibrations. Three different sources of random noises with an exponential correlation function are used to demonstrate the effect.

Dynamics of the N-pendulum and its application to a wave energy converter concept

Daniil Yurchenko, Panagiotis Alevras

International Journal of Dynamics and Control > 2013 > 1 > 4 > 290-299

This paper considers a design of an N-pendulum, which represents a special case of a physical pendulum. The design of the N-pendulum not only allows uncoupling the natural frequency of the pendulum from its length, but also provides easy control of the frequency and torque. The proposed design is stimulated by the idea of developing a wave power take-off system based on the parametric pendulum. Different...
