Abstract: Squeeze film damper has good vibration attenuation effect
to high-speed rotor. A grinding wheel spindle with squeeze film dampers
is designed base on the theory of squeeze film damping. Differential
equation of grinding wheel spindle center is established and the center
trace of grinding wheel center is established and the center trace of
grinding wheel spindle is simulated. A grinding experiment was done on a
high-precision hole grinding machine. The experiment result shows that
the squeeze film damper with reasonable parameters has supper
attenuating vibration property to grinding wheel spindle, and can
attenuate vibration of grinding wheel spindle 30% to 45% improve
machining quality of precision hole 10% to 20%, work efficiency of
machine tool 15% to 25%.
