【Abstract】 A new kind of adaptive damper composed of electrorheological (ER) fluids based on yield model is proposed in this paper. The damper was applied to vibration and chatter control during cutting. By analyzing the damping force and influenced factors, the model of single-degree-of-freedom (SDOF) isolation cutting system was obtained. The variation of damping ratio with input voltage was simulated and the method of voltage control is discussed.更多还原
