摘要
为了研究轿车轮胎地面磨擦力的作用效果,通过实验,利用测力装置测得轮胎地面摩擦力,并计算出附着系数.分析了轿车在启动、行驶、制动和转弯的过程中,整车的惯性力和轮胎转动的惯性力偶矩,以及由轮胎与地面的变形产生的滚动阻力偶矩.提出在几种行车状况下地面摩擦力和附着系数的计算方法,并通过算例进行讨论.
An experiment device was used to measure friction force, and the coefficient of ad- hesion was calculated. To investigate the interaction friction effect of the tire and ground, various conditions were analyzed, such as acceleration, braking and turning. Considering inertial force, moments of inertia and the resistance moment of rolling, a calculating method about friction force and the coefficient of adhesion was presented in the paper; and some calculation examples were discussed for car running progress.
