摘要

W artykule opisano badania pasywnych uk?adów kondycjonowania sygna ?u z generatora elektromagnetycznego, które zaprojektowano do zasilania t?umika magnetoreologicznego (MR) o ruchu liniowym. Przedstawiono uk?ady kondycjonowania zrealizowane na diodach Schottky'ego oraz przeka?nikach analogowych, stanowisko badawcze oraz wyniki badań. Dzia?anie uk?adów porównano analizuj?c charakterystyki cz?stotliwo ?ciowe i czasowe.%The paper deals with laboratory testing of passive conditioning systems improving the output signal of the electromagnetic generator used for a power linear magnetorheological (MR) damper. The generator, composed of permanent magnets and a coil with foil winding, produces electrical energy according to Faraday's law of electromagnetic induction. This energy is applied to vary the damping characteristics of the MR damper attached to the generator by the input current produced by the device. The objective of the conditioning systems is to improve the voltage signal applied to the control coil of the MR damper. The paper describes briefly the conditioning systems based on Schottky's diodes and analog relays, the experimental setup (the self-powered vibration reduction system based on MR damper for a one-degree-of-freedom object, measurement and control equipment) and the results of experimental tests. The performance of the developed conditioning systems is compared by analyzing the determined frequency and time responses.
