The dynamic response of railway bridges is important to consider, as the high velocity loading from trains increases risk resonance. Increasing train speeds and loads result in a need for adaptable properties bridges. One solution install magnetorheological dampers, structure originating moving could be controlled by alternating input current damper. However, complexity such devices results dif...

This study introduces an online reconfigurable road-adaptive semi-active suspension controller that reaches the performance objectives with satisfying dissipativity constraint. The concept of model is based on a nonlinear static Magnetorheological (MR) damper considering bi-viscous and hysteretic behaviors damper. input saturation problem has been solved by using proposed method in literature a...

As an important member of smart materials, magnetorheological elastomers (MREs) exhibit characteristics that their modulus can be controlled by an external magnetic field. Based on these experimental results, a viscoelastic solid model with four parameters was proposed to predict the performance of MRE. A building model, three stories high, was constructed using MATLAB SIMULINK to evaluate the ...

Many publications show that the ride comfort of a railway vehicle can be significantly improved using semi-active damping control lateral secondary dampers. However, efficiency depends on selection algorithm and damper dynamic behaviour, i.e., its force rise response time, drop time range. This paper examines influence these parameters magnetorheological (MR) S/A for several algorithms. One new...

In order to reduce vehicle vibration during driving conditions, a fuzzy sliding mode control strategy (FSMC) for semi-active air suspension based on the magnetorheological (MR) damper is proposed. The MR used in system was tested and analyzed. Based experimental data, genetic algorithm identify parameters of improved hyperbolic tangent model, which derived damper. At same time, an adaptive neur...
