Magnetorheological (MR) damper performance is evaluated only by single-field analysis in the design process, which can easily lead to larger errors. Based on this, a simulation method of MR considering multiphysics coupling was proposed. According certain automobile shock absorber requirement, an suitable for suspension designed. The mechanical model, electromagnetic field flow and structural s...

The structural parameters of the magnetorheological (MR) damper significantly affect output damping force and dynamic range. This paper presents a design optimization method to improve performance novel MR with bended magnetic circuit folded flow gap. multiobjective this was carried out based on optimal Latin hypercube (Opt LHD), ellipsoidal basis function neural network (EBFNN), particle swarm...

Magnetorheological (MR) technology has provided effective solutions to many engineering bottleneck problems due its controllable nature. However, designing a rotary MR damper with high torque–volume ratio is always challenging, especially for some specific application scenarios constrained space, such as robot joints. To solve this problem, based on bearings was designed and evaluated in study....

The vibration control of a seat suspension system with magnetorheological (MR) damper is investigated in this study. Firstly, a dynamical model of the seat suspension system with parameter uncertainties (such as mass, stiffness, damping) and actuator saturation is established. Secondly, based on Lyapunov functional theory and considering constraint conditions for damping force, the semi-active ...

Magnetorheological (MR) dampers represent one of the most promising semi-active control devices for applications aiming at the seismic risk mitigation of new or existing civil structures. Two 30 kN MR dampers were experimentally tested subjecting them to assigned conventional displacement laws at their ends. The paper describes the main results of the above experimental activity and aims at imp...
