Abstract:
Based on the basic idea of Bingham plastic model, a non-parametric model of magneto-rheological (MR) damper is proposed. ThisMR damper model assumes that the damping force of the MR damper consists of three parts: gas chamber force, viscous damping force of MR fluid, and damping force duo to the applied magnetic f ield. The gas chamber force is expressed as a function of the piston displacement. The damping force due to magnet ic field presents a hysteresis loop without linear increase. Sigmoid function is chosen to describe this hysteresis behavior. Its peak value is also a function of the applied current. The comparison of theoretical and experimental results shows that this non-parametric model reflects the dynamic behavior of the usedMR damper reasonably. The parameters in this non-parametric model have clear physical meanings, and they are easily determined through experimental data as well. The proposed non-parametric model is used to describe some MR dampers that have good linearity.
