Isolation Properties of Low-Profile Magnetorheological Fluid Mounts

This study evaluates the stiffness and damping characteristics of low-profile magnetorheological (MR) fluid mounts (MRFM) to provide a better understanding vibration improvements offered by such mounts, as compared with conventional elastomeric mounts. It also aims at assessing how much mount’s performance is due MR elastomer steel insert that used in MRFM. The includes design, analysis, fabrication, testing unique class MRFM suitable for isolation sensitive machinery sensors. compressed (squeezed) response dynamic force applied mount. test results are (rubber) same configuration MRFM, highlight changes frequencies ranging from 1 35 Hz. With no current supplied, has slightly higher nearly rubber slight increase attributed fluid’s compressive stiffness, which than rubber. When supplied significantly lower taper off level mount frequencies. Both directly proportional current. At maximum 2 A, 200% 700% tapering quite interesting intriguing. indicates delivers high when needed, while them not desirable.
