Abstract

The dynamic behavior of spindle hydrostatic bearings is considered. Mathematical model of hydrostatic bearing is given. Possibilities of regulators implementation are considered as one of the effective ways to improve the vibration stability. Sampling method is suggested to choose parameters of correcting RC-circuits. Transient processes at different operating regimes are calculated, corresponding linear-frequency characteristics are made.


Keywords: hydrostatic bearing, spindle unit, vibration stability, dynamic performance, membrane regulator, RC-correction
