Power Requirements for Wheels Operating in Fine-Grained Soils
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS
Pagination or Media Count:
A technique based on the U. S. Army Engineer Waterways Experiment Station mobility prediction system was developed for predicting power requirements as a function of system output pull coefficient for a given wheel equipped with pneumatic tire operating on clay and in a range from towed to 20 percent slip. In addition, separate relations of system output and system input torque coefficient as functions of slip can be predicted. Comparisons with data from vehicle field tests show fair to good agreement between measured and predicted performance parameters.
