This study investigates the potential of applying piezoelectric energy harvesting technology in airfield pavements, which can provide electricity for smart sensors and LED lights at airfield. The energy harvesting performance of piezoelectric transducers was evaluated based on mechanical energy induced by aircraft loading on taxiway and runway. Stacked piezoelectric transducer design was used in this study to estimate the power output of piezoelectric harvester embedded in wheel path. Three-dimensional finite element models were used to calculate stress pulses and magnitudes under different loading conditions. The critical pavement responses of flexible pavement related to fatigue cracking, shear failure, and rutting were analyzed. The simulation results quantified the expected energy generation and dynamic responses of flexible pavements at different aircraft loads, speeds, and pavement temperatures. The results provide suggestions for optimizing installation of energy harvester in airfield pavements.
Many of the asphalt pavement analysis programs are based on linear elastic models. A linear viscoelastic modelswould be superior to linear elastic mod...
A linear viscoelastic model has been incorporated into a three-dimensional finite element program for analysis of flexible pavements. Linear and quadr...
