Effect of Deflection Angle on Rolling Resistance Coefficient of Radial Tires in Cars

Ma Yiyang Wei Xiaochen Chen Taiji Jing Lixin

Abstract：For different specifications of car radial tires， the control variable analysis method is used to study the influence of the deflection angle （slip angle， camber angle） on the rolling resistance coefficient value of tires. The results show that by increasing or decreasing the angle degree of reasonable law and changing the direction of rotation， the rolling resistance coefficient value of the tire can be changed， so that it shows a certain law and trend.

Key words：deflection angle car radial tire rolling resistance coefficient value rotation direction
