Abstract

Abstract:

In order to improve the rotation accuracy of the machine tool spindle without increasing the mechanical structure complexity， by controlling the active single-sided film throttle valve， the oil film force of the hydrostatic bearing embedded with control recess is actively adjusted to control the radial motion of the spindle. The oil film force of the bearing was obtained according to the Reynolds equation and the flow continuity equation， then， the theoretical model of the spindle motion was established. Theoretical and experimental researches on active control of the spindle radial rotation error were carried out based on PID controller， and the spindle motions under different types of loads were compared and analyzed. The results show that the spindle center can be kept at the target position under fixed load with the control of active hydrostatic system. The amplitude of the spindle motion under dynamic load can be reduced effectively and the orbit center is closer to target position than that without control.

Key words: mechanical and electronic engineering, rotation accuracy, active control, hydrostatic journal bearing, spindle center motion
