OPTIMIZATION OF HOLLOW CANTILEVERED BORING BAR STIFFNESS

Autor: G. C. Barber, P. Szuba, L. Yang, Q. Zou

Publikováno v: Machining Science and Technology. 9:325-343

Precision line boring is a very demanding application in terms of both quality and production rate requirements. Machining of long bores as needed in cam and crankshafts of engine blocks requires use of dedicated equipment. In this research, cantilev

Study of Flow Characteristics of Lubricant in Spiral-Groove Bearings by the Fluorescent Method

Autor: Q. Zou, Y. Tian, X. Liu, S. Wen, G. C. Barber

Publikováno v: Tribology Transactions. 48:259-263

The hard disk drive spindle is one of the critical mechanical components in hard disk drives (HDDs). It has great influence on overall performance, including track density, data-transfer rate, energy consumption, noise, and so forth. Nowadays, HDDs w

Development of a laboratory test device for electrorheological fluids in hydrostatic lubrication

Autor: Qian Zou, G. C. Barber, W. Carlson, Q. Y. Jiang

Publikováno v: Tribotest. 11:185-191

Electrorheological (ER) fluids exhibit changes in their rheological behaviour in the presence of an external electric field. Research and development activities related to ER fluids and their applications have increased dramatically during the last f

Status of transmission line and matching network design and testing for the ITER ion cyclotron heating and current drive system

Autor: P.V. Pesavento, N. Greenough, S.L. Gray, David A Rasmussen, G. C. Barber, E. Fredd, R.M. Sanabria, Charlotte Barbier, R. H. Goulding, R.L. Moon, D. W. Swain, D. O. Sparks, R. B. Peters, M.P. McCarthy, W. J. Wolframe, Ian Campbell

Publikováno v: AIP Conference Proceedings.

The ITER Ion Cyclotron Heating and Current Drive System is required to deliver 20 MW of RF Power in the frequency range 40-55 MHz to ITER plasmas for pulse lengths up to 3600 s. Components used in the transmission line and matching system include 305

Numerical Simulation of Engagement of a Wet Clutch With Skewed Surface Roughness

Autor: G. C. Barber, H. Gao, M. Shillor

Publikováno v: Journal of Tribology. 124:305-312

The engagement of a wet clutch with skewed surface roughness was investigated. A Weibull asperity height distribution rather than a Gaussian one was utilized in the asperity contact pressure model. The combined effects of surface roughness and skewne

Fault current tests of a 5-m HTS cable

Autor: J.W. Lue, G. C. Barber, R.L. Hughey, Jonathan Demko, J.P. Stovall, U. Sinha, Michael J Gouge

Publikováno v: IEEE Transactions on Appiled Superconductivity. 11:1785-1788

The first industrial demonstration of a three-phase, HTS power transmission cable at the Southwire manufacturing complex is in progress. One crucial issue during operation of the 30-m HTS cables is whether they can survive the fault current (which ca

Experimental Determination of Bulk Temperature and Critical Temperature in Scuffing Resistance Evaluation of Gears

Autor: Q. Y. Jiang, G. C. Barber

Publikováno v: Tribology Transactions. 43:21-26

Based on gear scuffing results obtained on a high speed gear test rig, equations for calculating bulk temperature as well as critical temperature of a lubricant/steel combination are presented for ...

Development of the Lateral Effect Photo Diode Technique to Measure Oil Film Thickness

Autor: G. C. Barber, M. W. Witte, J. D. Hovanesian, D. G. Hillebrand

Publikováno v: Tribology Transactions. 41:382-386

A measurement technique was developed using the lateral effect photodiode method to determine oil film thickness and oil retention measurement. A position-sensing photodiode determined the change in position of a focused laser beam. The beam was refl
