Abstract

In this paper a brief review is presented on the working principle of anti-yaw damper used widely on EMUs (Electric Multiple Units). Based on the Maxwell model, the piecewise linear model was developed by considering the rubber joint stiffness, the oil stiffness and the piecewise characteristics of hydraulic damper. Then, dynamic characteristic test for an anti-yaw damper was carried out, from which the dynamic damping curve and the dynamic stiffness curve has been achieved. At last, comparing with the test results and conventional Maxwell model, the piecewise linear model turned out to be able to accurately reflect the dynamic characteristics of the anti-yaw damper, whether unloading or not.
