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 کاملA study on the characteristics of externally pressurized air bearings
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...

15 صفحه اولPerformance Evaluation and Economic Analysis of Minimum Quantity Lubrication with Pressurized/Non-Pressurized Air and Nanofluid Mixture
Abstract—Water miscible cutting fluids are conventionally used to lubricate and cool the machining zone. But issues related to health hazards, maintenance and disposal costs have limited their usage, leading to application of Minimum Quantity Lubrication (MQL). To increase the effectiveness of MQL, nanocutting fluids are proposed. In the present work, water miscible nanographite cutting fluids ...
متن کاملProspective evaluation of the self-pressurized air-Q intubating laryngeal airway in children.
OBJECTIVES To assess the clinical efficacy of the self-pressurized air-Q ILA™ (ILA-SP). AIM The purpose of this prospective audit was to evaluate the feasibility of the ILA-SP in clinical practice and generate data for future comparison trials. BACKGROUND The ILA-SP is a new first-generation supraglottic airway for children with a self-adjusting cuff and lack of a pilot balloon. METHODS...
