THE DYNAMIC CHARACTERISTIC ANALYSIS AND EXPERIMENTAL RESULTS OF HYDROSTATICAL BEARING AND ITS APPLICATION

Based on the consideration of the compressibility of air in the oil the theoretical analysis to the dynamic characteristic of the hydrostatic bearing are carried out the formulae for discriminating the dynamic stability of the hydrostatic bearing system and for evaluating the dynamic rigidity are obtained. The experiments have shown the validity of theoretical analysis proposed in this paper. The theoretical basis summarized can be consulted for design of the hydrostatic bearing. Applying the theoretical analysis to the practice is beneficial to solve the discriminating the dynamic stability of the hydrostatic bearing. Thereby the accuracy of manufacture of machinery parts is improved.
