Analysis the Structural Parameters of Multi-Ring Groove MRF Damper Affecting on the Damping Properties

Design of a new magnetorheological damper gap structure, combined with viscous lag model, analyzed the damper structural parameters, Design the damping devices with different sizes. Comparison of the structure of the damper with different sizes after experiment, finding that the structure parameters has a significant effect on the performance of the damper. Designing a reasonable clearance structure is very important for improving the performance of MRF damper． The experimental results and the model fit have a good fitting accuracy.
