摘　　要：针对不同规格的轿车子午线轮胎,采用控制变量分析方法,研究偏转角度(slip angle,camber angle)对轮胎滚动阻力系数值的影响。结果表明,通过合理规律的增加或递减角度度数及改变转动方向都可以改变轮胎的滚动阻力系数值,使其呈现一定的规律和趋势。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.

关 键 词：偏转角度 轿车子午线轮胎 滚动阻力系数值 转动方向
