共振頻率自我調整之彈簧式獵能器設計
Design of Spring Type Energy Harvesting Device with Self-Adjustment of Natural Frequency
摘要
本論文研製之可安裝於車輪的新型獵能器設計概念及分析，並可做為輪胎壓力感測系統之電源供應。組成包含作為質量塊的永久磁鐵，兩個彈簧，一個線圈和一個儲能電路組成。於彈簧質量系統在車輪轉動的重力變化產生振動，加上磁鐵、線圈及能量儲存電路就可形成一個磁發電機。本文的重點對於振動系統的分析，建立了線性及非線性的振動方程，可以建立一個電器阻尼線圈模型，並可以估算轉換後的能量大小。

This study is aimed at developing and analyzing a conceptual design of a novel energy harvesting device that can be mounted in a rotating wheel and used as a power supply of a tire pressure monitoring system(TPMS). The device is composed of a permanent magnet as a mass in the dynamic system, two springs and a coil set. The mass vibrates along the transverse direction due to the variations of the gravity force. The magnet, coils and an addition energy storage circuit will be integrated as a magneto-electric generator. This research established the nonlinear vibration equation based on the resonance frequency variation of the energy harvester to analyze its power generation and vibration. The electrical damping is considered to estimate the power output.
