电流变减振器用于铣床振动控制的试验研究

Experimental Research on the ER(Electro-Rheological) Damper for Milling Machine Vibration Control

试验研究了电流变减振器在铣床颤振控制中的应用。试验发现 ,电流变减振器的刚度及阻尼随外加电场强度的增加而增大 ,主振系统的振幅随电场强度的增加而减小。试验表明电流变减振器具有控振效果明显、结构简单的特点。只要场强选取适当 。

The application of an ER damper for milling machine vibration control is studied by some experiments. It is observed that the stiffness and damping of ER damper are enhanced with the increas,of electric field density and the vibratory amplitude of main vibration system is reduced by raising the electric field density.The experimental results show that ER damper characterized by obvious vibration control effects and simple structure. As long as the electrical field density selected is appropriate, the vibratory amplitude of milling cutter shaft system can be controlled.
