Elastohydrodynamic Traction Characteristics of 5P4E Polyphenyl Ether

Journal of Lubrication Technology, 1973
An elastohydrodynamic rolling disk test apparatus has been designed, built, and a matrix of traction data covering a range of loads, speeds, and temperatures have been obtained for 5P4E polyphenyl ether. Measured tractions are found to markedly increase with load and decrease moderately with rolling speed.

Alternate Launch and Recovery Surface Traction Characteristics

SAE Technical Paper Series, 1986
<div class="htmlview paragraph">The rapid repair of bomb-damaged runways is of increasing concern to the U.S. Air Force, therefore, expedient repair concepts are being developed. Aircraft performance effects imposed by the repair treatments include: tire flotation, aircraft weight, landing dynamics, and the forces generated at the tire/runway ...

Traction Characteristics of a MIL-L-7808 Oil

Journal of Lubrication Technology, 1976
Traction versus slip curves for a full matrix of loads, speeds, and temperatures are given for one MIL-L-7808. Hertzian contact pressures from 80,000 psi (551.6 MN/m2) to 150,000 psi (1034.2 MN/m2), speeds from 900 ips (22.9 m/s) to 1,820 ips (46.2 m/s), and temperatures from 75°F (23.9°C) to 160°F (71.1°C) are the test matrix limits of variation. Slip

Integral characteristics of branched tractional power-supply systems

Russian Electrical Engineering, 2012
A fast method is proposed for calculating the characteristics of tractional power-supply systems. The method is suitable for the power-supply systems of electrified railroad networks with a complex branched equivalent circuit (103–106 branches).

Influence of Battery Characteristics on Traction Drive Performance

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">The development of zero emission vehicles requires new concepts of the electrical drive train. On one hand the vehicle performance for a Californian electric vehicle must give high acceleration values together with enough vehicle range.

Traction Characteristics of Graphite Lubricants at High Temperature

Tribology Transactions, 1988
The high temperature (25°C to 538°C) traction characteristics of graphite lubricants containing additives of silver, phosphate glass, and zinc orthophosphate were evaluated in a specially designed ball-on-disk traction device. Bearing quality balls of hot-pressed silicon nitride burnished with the graphite lubricant were loaded against lubricated disks

Measurement and Modeling of Truck Tire Traction Characteristics

1992
A new truck tire tester was built to measure tire forces in braking and cornering under various speed, vertical load, and slip angle conditions, and on different pavement surfaces. Six of the most common truck and bus tires were tested. In general, rib tires performed better than lug tires and radial tires performed better than bias-ply tires.
