ABSTRACT


Hot isostatic processing (HIP) is the latest method to produce open porous materials, such as ceramics or metals. In this review paper, features and applications of HIPed porous materials are described. Sintering behavior under high pressure gas is also discussed in order to understand how porous materials are obtained by this method. HIPed porous materials have higher open porosity, higher mechanical strength, narrower pore size distribution and higher fluid permeabili ....etc

ACTIVE MAGNETIC BEARINGS (AMB)
A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active magnetic bearings (AMB) from pa ....etc

-: ABSTRACT:-
Bearings are valuable.... until they go bad, and then they are worthless. But the definition of Bad Condition of Bearing is not standardized yet. To quickly discover what bearings may be salvaged, we offers positive testing machine. Because “A Bearing Saved is a Bearing Earned”. We tried to compare the bearings on ideal and defective condition on Sound and Vibration factor. For Sound we used microphone and for Vibrations we implemented piezoelectric sensor. Instea ....etc

Abstract

Designing Magnetic Bearings

• Magnetic bearings are used to levitate flywheels so they can spin at high speeds without mechanical contact.
• The design of a bearing set to control a flywheel weighing 5100 lbs and spinning at 15,000 revolutions per minute was described in the paper, “Permanent Magnet Bias, Homopolar Magnetic Bearings for a 130 kW-hr Composite Flywheel,” by B. Murphy, H. Ouroua, M. Caprio, and J.Herbst.
• The paper was presented at the Ninth International Symposium on M ....etc
