Abrasive wear performance of various polyamides
(2002)Polyamides (PAs) form a major class of tribo-polymers used in almost all types of wear situations. They excel most of the engineering polymers especially in the case of abrasive wear performance. Since methylene (---CH2---) ... -
Acoustic emission in dynamic compression and its relevance to tribology
(1995)In the present work an acoustic emission (AE) technique is used to detec: the initiation and propagation of short cracks in compressive cyclic loading. A mild steel surface was subjected to cyclic compressive stress of 100 ... -
Analysis of simultaneous influence of operating variables on abrasive wear of phenolic composites
(2002)The paper deals with the abrasive wear investigations on various composites of phenolic resin filled with alumina powder and abraded against silicon carbide paper under dry and single pass condition. The data analysis was ... -
An analytical model for the prediction of the vibration response of rolling element bearings due to a localized defect
(1997)An analytical model has been proposed for predicting the vibration frequencies of rolling bearings and the amplitudes of significant frequency components due to a localized defect on outer race,inner race or on one of the ... -
Application of acoustic emission technique for the detection of defects in rolling element bearings
(2000)The usefulness of acoustic emission (AE) measurements for the detection of defects in roller bearings has been investigated in the present study. Defects were simulated in the roller and inner race of the bearings by the ... -
Applications of artificial intelligence techniques for induction machine stator fault diagnostics: review
(2003)The on-line fault diagnostics technology for induction machines is fast emerging for the detection of incipient faults as to avoid the unexpected failure. Approximately 30-40 % faults of induction machines are stator faults. ... -
Asperity level conformity in partial EHL part1:its characterization
(1996)Traditionally in partial elastohydrodynamic lubrication (EHL)the contact through lubricating films has been modeled assuming random contarct and taking into accountratio of film thickness to r.m.s roughness(h/o).In some ... -
