為了提高機車系統整體的能源有效利用率，本研究提出一種新型半主動混合式電磁避震器，主結構是使用一組互斥式永久磁鐵結合線性發電機，取代傳統式避震器的彈簧和阻尼減震筒，以達到可避震、可改變阻尼係數及可利用震動能量再生發電的功能。論文中將針對避震器的外觀尺寸、互斥永磁減震系統和電磁阻尼系統之設計細節，分別經由理論模型建構及有限元素分析三維(3-D)模擬的方式，提出一個有系統且完整的評估及設計流程。除了設計出能達到一般機車充電所需的12~14 V電壓及車燈照明所需的40 W功率。另一方面，亦將模擬在不同負載暫態下，所能達到的阻尼效應與發電效果，以確認此半主動混合式電磁避震器的可行性。

This research proposes a new type of semi-active hybrid electromagnetic shock absorber which can effectively harvest the inherent vibration energy for electric scooter application. The electromagnetic shock absorber combining the permanent magnet linear generator (PMLG) with a pair of permanent magnets (PMs) is mainly designed to replace the conventional mechanical shock absorber with variable damping. With systematic and thorough designs, it is believed that the proposed hybrid electromagnetic shock absorber can not only eliminate the shock forces but also generate the electric power applicable for scooter lighting or battery charging.
