abstract

Engine is one of the major sources of vibration in a vehicle. An engine mount is the device for isolating the body of vehicles from these vibrations. Harvesting the ambient energy of the vibrating fluid inside a hydraulic engine mount and converting it to the electricity is discussed in this paper. The energy harvester mechanism consists of two piezoelectric bimorph cantilevers with tuning tip masses with the beams covered by a thin layer of rubber. The deflections of the thin rubber layer induce vibrations in the beams which result in electrical power to be generated through the piezoelectric beams. The generated power can be used to recharge the battery for pressure sensors inside the engine mount. This novel harvester is tuned to work in the low frequency, high amplitude excitation environment of the engine. A mathematical model for this energy harvesting application is derived in this paper. Based on this model, the optimum load of the electrical circuit is also obtained. Simulation studies demonstrate performance of the energy harvester and predict the output voltage and maximum power which can be extracted from the energy scavenging device.
