Abstract

In this study a compact compressible magneto-rheological (MR) fluid damper-liquid spring (CMRFD-LS) with high spring rate is designed, developed and tested. The proposed device consists of a cylinder and piston-rod arrangement, with an annular MR fluid valve. The internal pressures in the chambers on either side of the piston develop the spring force, while the pressure difference across the MR valve produces the damping force, when the fluid flows through the MR valve. A fluid mechanics-based model is conducted to predict the behavior of the damper device under sinusoidal input. The device is studied under oscillatory vibrations for various frequencies and applied magnetic fields. The experimental results are in good agreement with the theoretical predictions.
