Design of magnetorheological damper with short time response

Abstract: For efficient fast control of suspension systems with magnetorheological dampers controlled by semi-active algorithms, the time response of the magnetorheological damper is one of the most important parameters which influences the performance of the suspension system. The time response of commercial magnetorheological dampers with common controllers is in the range of tens of milliseconds, which is too long for efficient real-time control of car suspension. This article describes the ways how to design magneto… Show more

“…2 left, number 1. The second motivation to use MRFs is in MR devices, as magnetorheological damper (Kubík et al, 2017;Strecker et al, 2015) or clutch (Imaduddin et al, 2015),because the same fluid is used for damping and sealing at the same time.…”

“…The response times of published designs of MR dampers are in the range of 20-100 ms [1], [3], [4]. From the existing literature, it can be assumed that the response time of MR damper has three sources [5], [6]: inductance of MR damper coil (response time of exciting current), response time of MR fluid, eddy currents in the coil core (response time of magnetic field in the active zone). The response time of MR fluid was estimated in the range of 0.45-0.6 ms by Goncalves [7].…”

“…Yang [1] published his findings that the use of a suitable current controller can significantly reduce the response time of exciting current. Strecker [5] stated that the response time of exciting current can be reduced to 1 ms. Eddy currents in the magnetic circuit create a time lag between the course of electric current and the course of MR damping force [8]. These currents produce a magnetic flux which flows in the opposite direction to the magnetic flux in the magnetic circuit.…”
