Magnetic Circuit Analyses and Turning Chatter Suppression Based on a Squeeze-Mode Magnetorheological Damping Turning Tool

Abstract EN

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.
