To solve the problems of small controllable range of dynamic stiffness, large field-off dynamic stiffness and limit stroke of the existing magneto rheological (MR) fluid mounts, a MR fluid mount with an inner bypass valve was proposed and developed. The MR fluid mount was designed to provide a wide range of dynamic stiffness in full working frequency range, small field-off dynamic stiffness and maximum stroke. Electromagnetic field simulation analysis of the MR fluid mount was carried out with a finite element simulation software. A mathematical model of the MR fluid mount was built. Experimental tests based on the servo-hydraulic test system were conducted. | | 查看全文查看/发表评论下载PDF阅读器 | |
