中文摘要 | 摘 要 磁流變液(Magneto-Rheological fluid,簡稱MR fluid)是一種新型的智能材料,是 由載液、磁性微粒及界面活性劑所組成。當未施加磁場時, 液體具牛頓流體 ( Newtonian fluid )的特性,在加入磁場後,數微秒內則流體變成賓漢性塑性體 ( Bingham plastic ),這種變化是連續、迅速、可逆,控制容易,故磁流變液裝置是一種 理想的半主動控制元件。 本論文設計磁流變液控制裝置如避震器、離合器及減震裝置等。使用Magneto V64 磁場分析軟體,對線圈進行磁路及磁場強度分析,探討磁場對磁流變液的剪應力效 應。磁流變液使用Lord 公司製作之MRF-132DG 磁流變液來進行模擬。由模擬分析結 果,電磁場分析軟體可提高對磁流變液裝置分析設計的效益,迅速獲得磁場對磁流變 液降服剪應力的影響。 |
英文摘要 | ABSTRACT Magneto-Rheological (MR) fluid is a kind of novel smart material. MR fluid is composed of based fluids, magnetic micro-particles and surfactants. When an external magnetic field is applied, the MR fluid changes from Newtonian fluid into Bingham plastic in few millisecond continuously, rapidly, reversibly, and was controlled easily. Therefore MR devices are ideal semi-active control elements. In this paper, MR devices that include MR damper, MR clutch, MR mount etc. are designed. Magneto V64 software was used to analyze the magnetic circuit and field strength of MR devices. MR fluid is MRF-132DG made by Lord Company. It analyses shear stress characteristics of MR fluid. From the results of magnetic circuit analysis, we can easily obtain the relationship between the magnetic field and the yield stress of MR fluid. It can improve designing MR devices. |
