A study on the characteristics of externally pressurized air bearings
نویسندگان
چکیده
In this study the direct numerical method is applied to solve the perturbed Reynolds" equation. To solve it the perturbed dimensionless mass f low rate is used as the boundary condition under the inherently compensated restrictor. The dynamic characteristics of a rotor supported in the externally pressurized air bearings, such as stiffness and damping coefficients, are analyzed, and as a result the orbit of the journal center due to rotating unbalance force is calculated. The diameter of the orbit has been experimentally determined based on the three-point method. The maximum difference between the measured and calculated diameters was less than 5%.

Shape optimization of pressurized air bearings
Use of externally pressurized air bearings allows for the design of mechanical systems requiring extreme precision in positioning. One application is the fine control for the positioning of mirrors in large-scale optical telescopes. Other examples come from applications in robotics and computer hard-drive manufacturing. Pressurized bearings maintain a finite separation between mechanical compon...
متن کاملExperimental Results of Pressure Fluctuations in a Water Conduit Section Due to Formation of Unstable Two-Phase Air-Water Flow
The study of two-phase fluid flow behavior in hydraulic structures such as pressurized flow tunnels, culverts, sewer pipes, junctions and other similar conduits is of great importance. A two-phase mixture flowing in a pipe can exhibit several interfacial geometries such as bubbles, slugs or films, depending on the fluid and hydrodynamic properties of flow. The main variables, giving rise to a v...

متن کاملLinear motion carriage with aerostatic bearings preloaded by inclined iron core linear electric motor
A fundamentally precise and simple linear motion axis design is discussed where the attractive force from the linear motor is used to preload a carriage supported by six rigidly attached porous carbon air bearings. The air bearings are assembled by vacuuming the pads to two orthogonal planes, positioning the carriage above the pads, and then injecting epoxy between the bearings and the carriage...
