New Results of Traction Force Calculations in Elastohydrodynamic Contacts
Journal of Tribology, 1985The lubricant shear modulus G and Ree-Eyring shear stress τ0 are determined in this work by using Roelands’, rather than Barus’, relationship for calculating the lubricant viscosity. When using Roelands’ viscosity, elastic effects in the lubricant tend to be negligible, especially when inlet shear heating and displacement of the center of pressure are ...

Calculation and Analysis of Traction Infinitely Variable Transmission
2011 Second International Conference on Digital Manufacturing & Automation, 2011Traction oil film thickness calculation is done on a kind of continuous velocity transmission which is named traction infinitely variable transmission (TIVT). It is proved that transmission type of TIVT is traction drive rather than friction drive through design on roughness, material of parts and traction oil.

A Means of Calculating Level Road Traction Requirements
SAE Technical Paper Series, 1962<div class="htmlview paragraph">Up to this time, level road traction requirements of a car could be determined only by various time-consuming road and bench tests. The development of a basic formula to compute loading for constant speed, level road operation has solved some of the cost and time problem and gives reasonable agreement with ...

Discrete Controlled Train Traction Calculation Model
International Conference on Transportation Engineering 2009, 2009In order to solute train traction calculation problem based on discrete control, the paper builds up a general train traction calculation model. The model includes multi-particle train model and three main operation processes. The processes are train start and acceleration process, adjustment velocity process and stop process.
