Capability Test and Vibration Analysis of Squeeze-Type Magnetorheologic Grease Damper

Abstract:

Magnetorheological grease is a new smart magnetorheological material with non-sedimentation problem after magnetorheological fluid and elastomer. Squeeze-type damper is designed with small displacement; vibration characteristic tests of magnetorheological grease damper are presented, and the test-data is processed with matlab software. Under different current and frequency, the characteristic relationship of damping force-displacement and changes of the indicator diagram are studied experimentally. It comes to the maximum effective load current and the maximum effective vibration frequency of magnetorheologic grease damper, and damping characteristic by data fitting. Though analyzing the vibration reaction, vibration characteristics are obtained, it can also provide important support for MRG damper in development and vibration applications.
