An innovative hybrid mathematical/computational scheme is built to evaluate the energy harvested by a mechanical system. The governing voltage differential equations of the piezoelectric composite beam are coupled with the finite element method output. The scheme is able of evaluating various excitation forms including dynamic force and base excitation. Thus, it provides the capability to analyse a complicated structure with a more realistic loading scenario. Application to the simulation of a notional jet aircraft wingbox with a piezoelectric skin layer is shown in some detail. The results pointed out that the electrical power generated can be as much as 25.24 kW for a 14.5 m wingspan. The capabilities and robustness of the scheme are shown by comparison with results from the literature.

Energy Harvesting Research: The Road from Single Source to Multisource

“…Harvesting vibrational energy dissipated from these structures could solve these issues. To date, many energy harvesting powered structural monitoring systems have been reported, including those for asphalt pavement, oil pump, vehicle suspension, bridge, vehicle tire, railway and train, and aircraft and spacecraft . There are also plenty of comprehensive reviews discussing the topic of vibrational energy harvesting …”

An iterative finite element method for piezoelectric energy harvesting composite with implementation to lifting structures under Gust Load Conditions

“…As reviewed in [31], Mainly the studies focused on resonance and instability phenomenon, i.e., Vortex-Induced Vibration, flutter. To the authors ′ knowledge, in addition to the works done by De marqui et al [13,14], only a few articles [34][35][36][37][38][39] presented the evaluation of the lifting structure under a more practical aerodynamic loading condition, i.e., cruise and gust loads.…”

“…Harmonic cruise loading condition was investigated by Akbar and Curiel-Sosa in [38]. A hybrid analytical/FEM scheme was proposed.…”

Evaluation of piezoelectric energy harvester under dynamic bending by means of hybrid mathematical/isogeometric analysis

“…To the authors's knowledge, there are only a few articles proposed models for gust load on wing structure (De Marqui Jr. and Maria 2010;Xiang et al 2015;Tsushima and Su 2016;Bruni et al 2017) . Akbar and Curiel-Sosa (2016) proposed the model for a more general condition, dynamic bending load. The model has been successfully implemented on a typical transport aircraft wingbox structure under dynamic cruise load.…”

“…The model has been successfully implemented on a typical transport aircraft wingbox structure under dynamic cruise load. Akbar and Curiel-Sosa (2016) proposed a hybrid scheme, in which conveniently coupled the piezoelectric beam voltage equation with the dynamic responses from FEM and analytical model. By means of this scheme, it is possible to implement the responses from the various computational model (not limited to finite element model) as input to the voltage equation to provide the power output estimation.…”
