Design of an Intelligent Module for Hydrostatic Bearing
2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2018This paper proposes an embedded system, as a major part of intelligent module, to improve the reliability and precision of the hydrostatic bearing, which is known as a key subsystem of precision machine tools. The embedded system integrated with sensory devices has two main functions: virtual metrology and fault diagnosis.

The dynamic characteristics of hydrostatic bearings
Wear, 1993Abstract The characteristics of hydrostatic bearings have been theoretically studied in terms of the compressibility of the air-contained oil. A formula for the stability criterion of a hydrostatic bearing system and a dynamic stiffness formula have been derived.

Wear, 1960
Orifice-regulated hydrostatic gas bearings offer significant advantages for instrument applications. In particular, gimbal bearings for inertial guidance systems can be designed with negligible starting torque and high stiffness, and for operation at extreme temperatures.

Characteristics of a hydrostatic thrust bearing
International Journal of Mechanical Sciences, 1962Summary The static and dynamic behaviour of a hydrostatic thrust bearing has been fully analysed starting from the Navier-Stokes equations for two-dimensional flow. An expression has been derived giving the force exerted by the oil in terms of the variables, amplitude of vibration, thickness of oil film and frequency.

Viscosity variation in hydrostatic bearings
Tribology, 1972Abstract Bearings which operate in extreme environments may incur problems due to: 1 - ambient temperature rise, from cold starting to normal running; 2 - temperature difference between the control system and the bearing. Several problems and the effects of the consequent viscosity variations are discussed, and some conclusions are reached concerning

Simple modeling of hydrostatic bearings
SPIE Proceedings, 2014Hydrostatic bearings are a key component for many large telescopes due to their high load bearing capacity, stiffness and low friction. A simple technique is presented to model these bearings to understand the effects of geometry, oil viscosity, flow control, temperature, etc. on the bearings behavior.
