Abstract :
The paper presents the research of a linear magnetorheological damper (MR) coil type RD-8040 produced by Lord Corporation. The aim of the research was to determine electrical characteristics for AC voltage supplying the MR damper coil. Understanding of the dynamic characteristics of the control coil is necessary for the proper selection of the parameters for current controllers supplying MR dampers. In order to know the dynamic characteristics of the damper control coil laboratory tests and numerical calculations were carried out. The tests were performed for sinusoidal voltage with an amplitude of 1 V and frequency changed in the range of 0.1-100 Hz. The results of the experiments were compared with the results of the simulation by step responses, the characteristics of amplitude-frequency and phase-frequency. This work will be used to build a model of a self-powered vibration reduction system equipped with a conditioning system.
