Experimental analysis of vibration isolation using hybrid magnet and magnetorheological fluid damper

Abstract

This work analyzes the effect of magnetic field strengths of actuators on the performance of vibration isolation of quarter car model. Hybrid magnet and magnetorheological fluid damper with the nano- and micron-sized iron oxide particles are employed as actuators in parallel with the conventional elements of the car model. Experimental work has been carried out on a laboratory scale model of a two degree of freedom quarter car with the help of electrodynamic shaker, accelerometers, data acquisition card and LabVIEW software. The performance is evaluated based on suspension deflection, tire deflection and transmissibility ratio. The improvement in the performance of the combined effect of actuators is better than the conventional and individual elements.
