,始于两侧的高温区在摩擦区中部汇合,发展成一个环状高温区,同时温度明显升高.在制动33 s时,达到整个制动过程的最高温度521 ℃,中部高温区处于显著扩展阶段.33 s后,高温区的温度变化不明显,其他区域的温度有所升高. 表1 3种摩擦副的平均摩擦因数 Table 1 Average friction coefficient of three friction pair... coefficient and disc surface temperature were investigated. The results show that the effect of the brake pad geometry on the friction coefficient is related to the braking conditions. At lower braking speed......
