Abstract

[automatically translated] The present work has as its object the numerical study of a magnetorheological fluid brake (MR) for automotive use by the finite element code ANSYS. Following a preliminary analytical dimensioning the brake, the realization of a magnetic FEM model enables accurate assessment of the distribution of the magnetic field in the MR fluid and the evaluation of the braking torque generated by the application of current to the coil. The subsequent optimization of the magnetic circuit in two stages allows to improve performance in terms of braking torque and weight of the device. The dynamic thermal FEM analysis finally allows to estimate the temperature trend in the brake during normal use by simulation of a cyclic test acceleration and braking.
