Virtual Determinations and Analyzes on the Influence of the MRD Magnetic Field from the Vehicle Structure in Assessing the Passenger Comfort During Travel

Abstract

The magnetorheological damping systems due to the relatively simple operating principle, but especially due to the efficiency of the functioning as compared to other types of shock absorbers, tend to occupy a wider range of use. In the field of motor vehicles, they are used for the shock and vibration damping systems, generated when traveling on roads with a non-uniform structure. With the change in vehicle development strategies, new systems and subsystems performance research is required. The purpose of this research is to identify as accurately as possible the magnetic field values created inside the damper so as to generate increased comfort in the seat for the vehicle’s staff. The correct determination of the current intensity values feeding the damper coil is essential for the accurate understanding of the dynamic behavior of the magnetorheological fluid inside the this. The research is aimed at using two virtual analysis software platforms: AMESim and ANSYS. The programs considered can make very realistic dynamic simulations, but at the same time bring economic efficiency from the point of view of research. The results are considered to be the correct utilization of the behavior of the magnetorheological damper under the influence of the current intensity, due to the dependence of the damping force on the created magnetic field, the amelioration of shocks and vibrations and for the increase of the degree of comfort in the seat.
