分析了盘式制动器的产热机理及热量分配，利用ANSYS建立三维有限元模型，仿真得到恒定、渐变、正弦三种载荷形式下的制动盘温度场。结果表明，制动盘摩擦区域内节点温度呈锯齿状波动上升，沿制动盘轴向，距摩擦表面越远，温度越低，波动幅度越小；沿制动盘径向，不同半径处的节点温度不同，摩擦区域中间位置温度最高，存在较大的径向温度梯度；沿制动盘周向，随着制动时间的增加，温度分布趋于均匀；恒定载荷下，制动盘表面的温升最大，正弦载荷下的温升最小。

Thermogenesis mechanism and heat distribution of disc brake were analyzed, the 3-D finite element model was built with ANSYS and the thermal field of brake disc under constant load, graded load and sine load was got through simulation. The results show that temperature of node in friction region rise hackly, along axial of brake disc, the temperature and fluctuation range decrease with the increase of distance between node and friction surface;the temperature of nodes at different radius are distinguishing and it is highlighted at the middle of friction region ,so this causes radial temperature gradient; the temperature distribution along circumference is becoming uniform with time increase;temperature of brake disc surface under the constant load is the highest and which under the sine load is the lowest.
