摘要

磁流变弹性体(MRE)是一种智能材料,它可以通过暴露在电场、磁场、应力、湿度和温度等刺激下改变其性能。本研究的目的是研制一种MRE作为梁夹层在不同电流下的隔振器,以获得不同的MRE刚度。将硅橡胶、硅油和羰基铁颗粒混合在一起,然后在圆形模具中固化24小时,制成MRE。实验结果表明,当施加在线圈上的电流增大时,在时域和频域的振动幅值都减小。

Vibration Control of Magnetorheological Elastomer Beam Sandwich
A Magnetorheological Elastomer (MRE) is a smart material and that could change their properties by exposure to stimuli such as electric and magnetic fields, stress moisture and temperature. Objective of this research is to develop a MRE as vibration isolator of a beam sandwich under different currents to get different stiffness of the MRE. A MRE was fabricated by mixing silicon rubber, silicon oil and carbonyl iron particles together and then cured for 24 hours in a circular mold. Experimental result shows that that there were decreases in amplitude of the vibration in time and frequency domains when the current applied to the coil is increased.
