摘　　要：运用ANSYS建立盘式制动器热传导的有限元模型,分析对流系数以及制动方式对制动盘表面温度的影响。结果表明:对流系数对制动过程中制动盘表面的最高温度的影响很小,对流换热主要在制动结束后的冷却过程中起作用;不同的制动方式将会产生不同的温度分布,在制动接触时间相同的情况下,点刹制动利于表面温度的降低,尤其是制动接触时间较短时温度降低效果显著。The finite element model of heat conduction of the brake disk was built by ANSYS software, and the influences of convection coefficient and braking types on the surface temperature of brake disk were studied. The results show that the convective heat transfer mode has little effect on the maximum contact temperature, but it has obvious effect on the maximum contact temperature at the cooling process after the end of braking process. Different type of brake results in different temperature distribution on the brake disk. Under the condition of same braking contact time, the braking type with spacing interval is conducive to the reduction of the surface temperature especially when the contact time is short.
