진동기반형 자가발전기의 내구성능시험절차

초록

This study aims to develop a durability test procedure for a vibration-based energy harvester on the frequency domain. Firstly, we investigated the vibration environment of structure on which the energy harvester may be installed and determined the level and frequency range of PSD exerted on the energy harvester. Consequently, we developed the test procedure which is composed of the PSD and sinusoidal sweep loads. And test system was built using the vibration exciter, data acquisition unit and LabView-based control software. Using the realized test system, durability performance tests for energy harvesters of 2 types were performed according to the established test procedure.
