MATHEMATICAL MODELS FOR PREDICTING THE TRACTIVE CHARACTERISTICS OF TRACTOR TIRES I: TRACTIVE EQUATIONS MODEL

摘要

Development a mathematical model for predicting the tractive characteristics (net traction ratio, gross traction ratio, tractive efficiency and rolling resistance ratio) as a function of soil cona index, tire parameters, and tire load, by using dimensionless numerics. The accuracy of prediction was chacked by experiments. This model may be used to predict the performance of any tire under any soil conditions.
