摘要
本文用电流变仪对BW型电流变液体进行测试,并将其用于筒式车用减振器。通过台架试验研究了激振频率、振幅对电流变液体减振器性能的影响,并就电流变液体减振器要求的流体性能进行探讨。研究结果表明,低频大振幅下,随着电场强度变化电流变液体减振器阻尼力变化显著;应用具有电粘特性的流体作为该电流变液体减振器的工作液更有价值。
In this paper, the BW type electrorheological fluid (ERF) has been tested by HAAKE rheometer and been used in a cylinder type shock absorber. Through bench testing the influence of the excitation frequency and the oscillation amplitude on the performance of a shock absorber with electrorheological fluid is studied and the behaviors of fluid requested by shock absorber is discussed. The testing result shows that the damping remarkably varies with the change in electric field intensity under low frequency and large amplitude, and electroviscous fluids as electrorheological fluids is of much greater value to shock absorber.
