Nonlinear dynamics of a heaving spar-floater system integrated with inerter pendulum vibration absorber power take-off for wave energy conversion

A power take-off based on the inerter pendulum vibration absorber (called IPVA-PTO) is integrated with a spar-floater system to study its hydrodynamic response suppression and wave energy conversion capabilities in regular waves. The hydrodynamics of the spar-floater system is computed using the boundary element method with linear wave theory. With the wave height and wave frequency as the bifurcation parameters, it is found that the system can undergo two bifurcations: period-doubling bifurcation around the first resonance frequency (spar mode) and secondary Hopf bifurcation around the second resonance frequency (floater mode). The period-doubling bifurcation results in an energy transfer between the spar-floater system and the IPVA-PTO for small electrical damping values. As a result, the IPVA-PTO system simultaneously reduces the maximum response amplitude operator (RAO) of the spar and …

The inerter pendulum vibration absorber is connected with a power take-off mechanism (called IPVA-PTO) to study its wave energy conversion potential. The resulting IPVA-PTO system is integrated between a spar and a floater (torus) using a ballscrew mechanism. The hydrodynamic stiffness, added mass and radiation damping effects on the spar-floater system are characterized using boundary element method via Ansys Aqwa. It has been observed that a 1:2 internal resonance between the spar-floater system and the pendulum is responsible for nonlinear energy transfer between the two systems. This nonlinear energy transfer occurs when the primary harmonic solution of the system becomes unstable, and a secondary solution emerges in the system characterized by harmonics of frequency half the excitation frequency. As a result of this energy transfer, the vibration of the spar-floater system is …

The Inerter Pendulum Vibration Absorber: With Applications in Ocean Wave Energy Conversion and Hydrodynamic Response Suppression

The annual power incident on the ocean-facing coastlines of North America is over 400 GW. Capturing a small fraction of this energy can significantly contribute to meeting energy demands. Therefore, there is a renewed research interest in converting energy from ocean waves. Typically, ocean wave energy capturing devices, known as wave energy converters (WECs), are placed in deep water as the wave energy is higher in the deep water compared to shallow water. To reduce the cost of installing and maintaining WECs in deep water, they can be integrated with existing offshore floating platforms in the ocean. For such integration, traditional WECs, operating on the principle of linear resonance, have a natural period in heave close to a typical wave period to generate a large heave resonant response and hence high-efficiency wave power production, which causes large platform motions. In other words, wave …

The inerter pendulum vibration absorber (IPVA) is integrated between a spar and an annulus floater using a ball-screw mechanism to study its wave energy conversion potential. Hydrodynamic stiffness, added mass, and radiation damping effects on the spar-floater system are characterized using the boundary element method. It is found that a 1: 2 internal resonance via a period-doubling bifurcation in the system is responsible for nonlinear energy transfer between the spar-floater system and the pendulum vibration absorber. This nonlinear energy transfer occurs when the primary harmonic solution of the system becomes unstable due to the 1: 2 internal resonance phenomenon. The focus of this paper is to analyze this 1: 2 internal resonance phenomenon near the first natural frequency of the system. The IPVA system when integrated with the spar-floater system is shown to outperform a linear coupling between …

Ocean wave energy conversion of a spar platform using a nonlinear inerter pendulum vibration absorber

A nonlinear inerter pendulum vibration absorber is integrated with an electromagnetic power take-off system (called IPVA-PTO) and is analyzed for its efficacy in ocean wave energy conversion of a spar platform. The IPVA-PTO system shows a nonlinear energy transfer phenomenon between the spar and the IPVA-PTO which can be used to convert the vibration energy of the spar into electricity while reducing the hydrodynamic response of the spar. The hydrodynamic coefficients of the spar are computed using a commercial boundary-element-method (BEM) code. It is shown that the energy transfer is associated with 1:2 internal resonance of the pendulum vibration absorber, which is induced by a period-doubling bifurcation. The period-doubling bifurcation is studied using the harmonic balance method. A modified alternating frequency/time (AFT) approach is developed to compute the Jacobian matrix …

The inerter has been integrated into various vibration mitigation devices, whose mass amplification effect could enhance the suppression capabilities of these devices. In the current study, the inerter is integrated with a pendulum vibration absorber, referred to as inerter pendulum vibration absorber (IPVA). To demonstrate its efficacy, the IPVA is integrated with a linear, harmonically forced oscillator seeking vibration mitigation. A theoretical investigation is conducted to understand the nonlinear response of the IPVA. It is shown that the IPVA operates based on a nonlinear energy transfer phenomenon wherein the energy of the linear oscillator transfers to the pendulum vibration absorber as a result of parametric resonance of the pendulum. The parametric instability is predicted by the harmonic balance method along with the Floquet theory. A perturbation analysis shows that a pitchfork bifurcation and period …

Existing Energy Harvesting Shock Absorbers (EHSAs) of vehicle suspensions are mainly designed based on the principle of linear resonance, thereby compromising suspension performance for high-efficiency energy harvesting and being only responsive to narrow-bandwidth vibrations. In this paper, we propose a new EHSA design – inerter pendulum vibration absorber (IPVA)– that integrates an electromagnetic rotary EHSA with a nonlinear pendulum vibration absorber. We show that this design simultaneously improves ride comfort and energy harvesting efficiency by virtue of the nonlinear effects of pendulum’s inertia. To further improve the performance, model predictive control (MPC) is designed and evaluated in two cases. In the first case, we directly exploit the nonlinear dynamics of the proposed EHSA into a nonlinear MPC (NMPC) design. In the second case, we develop a novel stochastic linearization …

Vibration suppression has been a widely studied topic for a long time, with various modifications in passive vibration mitigation devices to improve the efficacy. One such modification is the addition of the inerter. The inerter has been integrated into various vibration mitigation devices, whose mass amplification effect could be used to enhance the performance of dynamic vibration absorbers. In the current study, we consider an inerter based pendulum vibration absorber (IPVA) system and conduct a theoretical study on vibration suppression of the device. The IPVA system operates based on the principle of nonlinear energy transfer, wherein the energy of the primary structure is transferred into the pendulum vibration absorber. This is the result of parametric resonance of the pendulum, where the primary resonance of the system becomes unstable and a harmonic regime containing a frequency half the resonant …

Inerter-based vibration energy harvesters (VEHs) have been widely studied to harvest energy from large-scale structural vibrations. Recently, there have been efforts to increase the operation frequency bandwidth of VEHs by introducing a variety of stiffness and inertia nonlinearity. This paper proposes a new inerter-based VEH comprising an epicyclic-gearing inerter and a pendulum vibration absorber. The centrifugal force of the pendulum introduces a new type of inertia nonlinearity that broadens the frequency bandwidth. This inerter-pendulum VEH (IPVEH) is incorporated in a single-degree-of-freedom structure to demonstrate its performance and the equations of motion of the system are derived. The method of multiple scales is applied to derive the amplitude–frequency response relationship of the harvested power in the primary resonance. The harvested power is optimized through tuning the harvester’s …
