摘　　要：运用热传导理论对盘式制动器温度场建立热传导方程及边界条件.通过Workbench有限元分析软件模拟仿真盘式制动器的制动工况.分别分析了制动盘和闸瓦在制动过程中的温度特性.结合实验探讨了制动盘径向轴向不同节点的温度变化规律,结果表明:随着制动盘转速的减小。制动盘和闸瓦的温度均表现出先上升后下降的趋势,制动盘温度梯度沿径向方向分布较明显,节点半径越大,热流密度输入越大.温度变化越明显。Based on the theory of heat conduction establishing heat conduction equation and boundary conditions on the temperature field of disc brake.The temperature field of the brake disc during the braking process are simulated by Workbench.The temperature characteristics of brake disc and brake shoe during braking are analyzed.The temperature variation on the different radial axial nodes of the brake disc is discussed by the experiment.The results show that with decreasing speed of brake disc, brake disc and brake shoe temperature showed a downward trend after the first rise.Brake disc temperature gradient along the radial distribution are obvious.The greater the radius of the node is,the greater the input of the heat flux is,the more obvious the-temperature changes.
