The bearings with variable damping characteristics are very important for floating slab track (FST) to restrain vibration in low frequency. A model with single degree of freedom of FST is built. Based on analyzing the characteristic of the magnetorheological grease (MRG) materials, a MRG isolator is proposed to instead of passive bearings of FST. For attenuating the vertical vibration, the method of adaptive particle swarm optimization (PSO) with variable inertial parameter is proposed to adjust the damping. The results simulated in MATLAB show that MRG isolators with the adaptive PSO algorithm can optimize damping at different excitations effectively and conspicuously decrease the low frequency vibration energy of FST.
