OPTIMAL METHODS OF THE DYNAMIC PROPERTIES IN A HYDROSTATIC BEARING SYSTEM

Abstract

Abstract: A new method is presented, to analyse and optimize the dynamic characteristics of self-adaptive hydrostatic bearing system with throttle. For the various correcting units are inserted. Dynamic properties of this system are effectively improved and rotary precision of the spindle is advanced. Based on the theory of stability for automatic control, the graphics of transient process and the logarithmic phase-frequency and amplitude-frequency characteristics of the system are analyzed before and after improvement. Influence on dynamics of the different methods is evaluated and their applied range is explained. The theoretical basis is provided for improving dynamic properties and optimization design of the hydrostatic bearing system.

Key words: Dynamic properties, Hydrostatic bearing, Logarithmic phase-frequency and amplitude-frequency characteristics, RC-Chain, Transient process
