摘要
研制了一种内通道式磁流变阻尼器,该阻尼器的流场通道位于电磁线圈内部,磁流变效应发生于两层固定的平板之间。对该阻尼器进行了MTS动态拉伸实验,结果表明具有良好动力学特性和响应时间。为了模拟动车的振动情况,搭建一个两自由度的弹簧质量实验平台系统,利用天棚控制算法,在该实验平台上进行减振实验研究,结果表明磁流变阻尼器在1 Hz～2 Hz频率范围内有较好的减振效果。
A kind of inner-pass magnetorheological（MR） damper was designed,whose damping passage is within the electromagnetic coil and in which the MF effect prevails in the region of fixed gap between two parallel disks.The dynamic property and response time of MR damper were tested by using the load frame of a material test system（MTS）.To simulate the vibration of a high speed train,a platform of double mass spring system was built,and with skyhook control,the damping effect of the MR damper was studied,which shows that MR damper is effective for vibration reduction in the frequency range from 1 Hz to 2 Hz.
