Abstract：A detecting system for performance of MR dampers was designed and developed. It could perform damping force-displacement tests and velocity feature tests of a MR damper under different excitations. Its electro-hydraulic position servo system was studied, a new real-time iteration control algorithm base on amplitude correction was proposed. Test results showed that this new control algorithm can effectively improve the amplitude-frequency characteristic dropping problem under higher frequency to reproduce sine displacement signals with higher accuracy and higher band width. Furthermore, a performance test for a LORD RD-8041-1 MR damper was conducted with this detecting system. Test results showed that this system can effectively detect the MR damper’s hysteretic characteristics curve to provide a premise for studying the dynamic model of the MR damper.
