Parameter Optimization Experiment of Magnetorheological Bearing

Abstract:

The active bearings with variable damping and stiffness are important for vibration isolation in wide frequency excitation. A model of vertical isoaltion system via magnetorheological (MR) bearings was built. Based on analyzing the characteristics of MR grease and MR elastomer, an MR parallel-isolator was designed to instead the passive bearing.Then an adaptive particle swarm optimization (PSO) was adopted to adjust the parameters of MR bearing. A vertical MR isoaltion experiment was proposed. Results demonstrate that MR bearings have better performance than passive bearing in concurrently restraining force transmissibility and vibration acceleration.
