| Abstract [eng] |
Research project is concerned with piezoelectric vibration energy harvesting intended for powering sensors of a lifting and storing system. A concept of energy-autonomous lift platform was proposed for detailed investigation by a manufacturer of lifting and storing systems with the aim to conduct feasibility study regarding application of piezoelectric vibration energy harvesters in heavy-payload pallet lifting and storing system in order to determine the viability of proposed energy-autonomy concept. An extensive literature review on the state of the art in mechanical energy harvesting was carried out, revealing that contactless excitation via magnetic plucking of piezoelectric transducers may be considered as a suitable vibration energy harvesting method within the scope of current project. Specified pallet lifting and storing system was examined in detail as the targeted use case for the energy harvesters in the context of implementation of energy-autonomous lift platform. Experimental investigation of the performance of the selected piezoelectric vibration energy harvesters was conducted by reproducing the actual excitation and geometrical conditions to be expected when deploying the harvesters in the specific pallet lifting and storing system. Final proposal excludes piezoelectric vibration energy harvesting because it was demonstrated to underperform under given application-specific operational conditions. As energy-autonomous concept in heavy storing system conditions proved to be insufficient, proposal was made to target low-payload storing systems instead. Although energy-autonomous solution was not achieved in heavy pallet lifting and storing system, alternative cost-effective near-energy-autonomous solutions for heavy storing systems were proposed. |
