摩擦副结构是影响制动盘温度分布的重要因素之一。针对闸片形状为圆形、三角形和六边形三种结构的摩擦副，采用制动试验台进行了速度为50～250 km/h的制动试验，并利用ABAQUS软件数值模拟了三种摩擦副不同工况条件下制动盘温度场的变化过程。结果表明：数值模拟温度场与试验测试结果具有良好的相似性。摩擦副结构对盘面温度分布的影响程度与制动条件密切相关，其结构形式对制动盘面温度的影响程度在制动初期最为明显，且随制动初速度和制动压力的增加而增加。这缘于闸片结构的不同导致了摩擦面摩擦弧长分布的不同，随制动速度升高和压力增加，摩擦弧长的差异起到了放大能量差别的作用，从而表现制动盘温度分布对闸片结构的敏感程度增加。

The pattern of a friction pair is an important factor affecting the friction braking temperature. Focusing on three different patterns of friction pairs formed with round, triangle and hexagon pad, braking experiments are conducted on an inertia test bench under the conditions of 50-250 km/h initial velocities. Using ABAQUS software simulation three kinds of the friction brake disc temperature field are conducted under different conditions. The results indicate that the numerical simulation of the temperature field matches the experimental results well. The influence of the friction pair structure on the disc surface temperature distribution is closely related to the braking conditions and is most obvious at the beginning of braking, and increase with the increase of braking initial velocity and braking pressure. This is because different structures of the friction pair lead to different distributions of the arc length. Friction arc length differences in turn amplifies the energy difference with the increase of the braking speed and high pressure, resulting in increased sensitivity of the brake disc temperature distribution to the brake pad structure.
