This paper presents a comparative study between different nonlinear damper models, developed for semi-active Electro-Rheological damper. The first model is by extending the hysteresis to obtain dynamic characteristic of To improve accuracy capturing damper’s behavior, Bouc-Wen using parameter-varying functions control input and state. One key points in proposed models describe dynamics controll...

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...

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...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

Primary suspension is the term used for suspension components connecting the wheel assemblies of a vehicle to the frame of the vehicle (Fig.1). This is in contrast to the suspension components connecting the frame and body of the vehicle, or those components located directly at the vehicle’s seat, commonly called the secondary suspension. Usually a vehicle contains both primary and secondary su...
