磁流變液簡稱MR，其機械性質可於瞬間隨磁場改變且易於控制，其反應過程是一種可逆且易於控制的機制。本文將其應用於國產槽式洗衣機的減振器上，模擬洗衣機加裝MR減振器後脫水時的振動分析，並透過對MR減振器電流改變的控制策略，以有效抑制洗衣機在共振轉速時所產生的極大的振動量。由電腦計算與實驗測試分析結果顯示，當偏心質量為1㎏，MR減振器通入電流1安培時，可達到良好之減振效果。

The mechanical property of magnetorheological (MR) fluid can be rapidly changed by the application of magnetic field and easily controlled. The process is reversible and controllable. This paper analyzes the vibration of domestic single-tub washer in dehydration process. The analysis is conducted by simulating the washer that is equipped with MR damper and uses the strategy of current changing in the MR damper to suppress the amplitude of resonance frequency. The computer simulation result show that when 1 ampere current is applied in the MR damper of the washer with eccentric mass 1 kg, the vibration can be effectively decreased.
