【Abstract】 Squeeze Film Damper has good vibration attenuation effect to grinding wheel spindle of hole grinding machine,but design parame ters of squeeze film damper have grea t effect to its vibration attenuatio n effect.If the parameters are not rea sonable it not only has vibration att enuation function but also causes a l ot of nonlinearity response.Optimum d esign parameters can be gained throu gh vibration attenuation effect sim-ulation of squeeze film damper.Kinetic model of grinding wheel spindle with squeeze film dampers that sim-ulation is need was established.更多还原
