Human simulated intelligent control on magneto-rheological vibration isolation system for subway floating slab track with moving load

Isolator with adjustable stiffness and damping is significant for the subway floating slab track to achieve vibration isolation control in a wide frequency range. Firstly, the dynamic model of long beam floating slab tack vibration system with moving load is built. And then the HSIC (Human simulated intelligent control, HSIC) optimization algorithm is proposed based on the vertical vibration. After that, the HSIC system for long beam floating slab track with multiple isolators is built, where magneto-rheological isolators and rubber isolators are parallel used. Finally, a comparative analysis of isolation effect is carried out with MATLAB in the simulated moving load excitation conditions. The results show that the MR isolators which are connected in parallel in the case of long beam can change with the excitation force of moving load to achieve the on-line adaptive optimization for the parameters of stiffness and damping. The root mean square value of the vibration force that tracks overall transmitted to the ground has decreased by 31.44%. And the shake of the floating slab is controlled within a reasonable range.
