“…To model the dynamics of a bridge with a moving vehicle, we consider a beam with a moving point load (Fryba, 1999), as shown in Figure 1. This model has been validated by Stancioiu et al (2011) and is the simplest model that includes the bridge dynamics. Other factors may be included, but that would complicate the system dynamics.…”

This article investigates the possibility of piezoelectric energy harvesters as energy scavenging devices in highway bridges. The structural vibration due to the motion of a load (vehicle) on the bridge is considered as the source of energy generation for the harvester. The energy generated in this way can be useful for wireless sensor networks for structural health monitoring of bridges by reducing or even eliminating the need for battery replacement/recharging. A highway bridge model with a moving point load is investigated and a linear single-degree-of-freedom model is used for the piezoelectric energy harvester. Two types of harvesters, namely, the harvesting circuit with and without an inductor, have been considered and the energy generated for a single vehicle has been estimated. These results may be used, together with traffic statistics, to obtain the variation of average power and thus, for a given application, help to design the energy management system.

“…It appears that the classical analysis of the studied system is generally based on an implicit assumption that these twin waves behaviours are found in a squeezed form or are short-lived. However, many numerical and experimental studies on this type of system 13–16 have reported colourful eccentric oscillation behaviours. Recent analytical work 8,17 has shown that the moving particle pumping effect can be modelled as multi-octave parametric excitation of the structure modal oscillations.…”

The interaction of a mechanical oscillator with the operation actions and environment fields will give rise to the splitting of normal modes. In this study, we investigate the normal mode splitting behaviour of a moving-particles-pumped single-span clamped-hinged elastic homogeneous beam based on the proposed multi-octave modal parametric oscillation model. Numerical experiments show the entangled and squeezed oscillations of the phase-conjugated waves near the resonance tongues. Theoretical analysis predicts the occurrence of multiple simple resonances and the squeezing of the twin waves modal oscillation in the region with a low speed of movement for the studied system.

“…Results of Michaltsos effort show that while the moving mass is small enough compared to the beam’s mass, the response of the beam under moving mass is not far from beam response to moving load. Stancioiu et al (2011) studied the moving mass problem experimentally for a multi-span flexible structure. Also Fryba (1999) has made a comprehensive study on various kinds of beam and plate vibration problems due to moving loads.…”

In this article, energy harvesting from a beam with traveling mass is studied. Harvesting was carried out by attaching a thin piezoelectric patch directly on the beam. A theoretical formulation was presented for the problem of energy harvesting from moving mass on a simply supported beam. To validate the results, an experimental setup was designed and fabricated to measure the beam response and voltage induced in the piezoelectric patch during the mass traveling on the beam. The results indicate that the analytical and experimental values for the beam midpoint deflection and the piezoelectric voltage are in good agreement. Finally, the effect of resistive load on the harvested power was considered and the optimum resistive load for maximizing the power was calculated.
