As a smart material, magnetorheological fluid (MRF) has been utilized in fields including civil engineering and automotive engineering, and so on. In this study, the MR damping turning tool based on the squeeze-mode was developed to improve the vibration resistance of the tool system on the lathe. The 3D magnetic circuit simulations of the damper were performed. The influences of damper structural parameters, such as coil positions, plate thicknesses, and others, on the magnetic induction strength were investigated. Orthogonal experiments were carried out and the optimal combination of damper parameters was determined. The chatter suppressive experiments were carried out to evaluate the performance of the MR damping turning tool.

Magnetorheological damper (MRD) is widely used in civil engineering, heavy-duty vehicles to speed up safely and so on. In this paper, a MR controller for adjusting the stiffness and damping of a semi-active air suspension is designed to improve the vibration resistance of the Electric Multiple Units (EMU) suspension system. The 3D magnetic field simulations of the MR controller are carried out. The influences of factors such as shaft material, damping channel width, cylinder wall thickness on the magnetic induction intensity at the damping channel are studied. An orthogonal experiment is carried out and the optimal combination of the structural parameters is determined. Then, the four working conditions of the MR controller are simulated and analyzed respectively, and its structure is improved to ensure its stability. Finally, using fluid simulation software analysis, it can be seen that due to the fluidity of magnetorheological fluids (MRFs), the heat generated by the coil has little effect on MRFs.
