摘要

磁性流變液體（Magnetorheological Fluid，簡稱MR）在工業界應用相當廣泛，尤其是在機械、化工和光電工業上。其和傳統塑流液體之主要區分，在於外加一個磁場時，其流體的流變特性會隨著外加磁場強度大小及頻率而有顯著和快速的變化。
半主動概念爲近年來減振研究的重要課題。半主動控制是一門新技術，其綜合了被動控制系統的穩定性與主動控制系統的機動性，達到低耗能、高出力、易於維護、可靠性高之致動器與控制系統。因其穩定性高、耗能低，僅需極少之控制能量即達到相當不錯之減振效果，以致學術界及工業界對其抱以厚望，紛紛投入研究。
本研究使用「磁流變阻尼器」(MR Damper)，運用MTS 810材料控制系統，研究漆包線線圈纏繞匝數、阻尼器套筒、繞漆包線套管、阻尼器填充液之套組，在不同的電壓，振幅及頻率下所達成之消能效果

The application of the Magnetorheological (MR) fluid is very board, especially in the mechanical, chemical and optical industry. In contrast to the traditional viscoplastic fluid, the flow characteristic of the MR Fluid could be changed when applying an external magnetic field. The hydrodynamic mechanism altered when the strength of the applying field decreased or increased.
The semi-active control is an important concept for studying vibration reduction in recent years. It is a highly dependable mobilizing device and control system that integrates the stability of passive control system and mobility of active control system to reach the goals of low energy consumption, high performance, and easy maintenance. Because of its excellent stability and low energy consumption that only takes minimum energy to reach effective vibration reduction, this latest technology was studied intensively in both academic and industrial fields.
This research use the Magnetorheological Damper device (MR Damper) and utilized MTS 810 material control system to examine the effects of different levels of voltage, amplitude and frequency on energy reduction. A combination of the number of circles of wire, damping tubes, enameled wire sleeves, and liquid of IVIR damper was used as control to increase the damping force.
