摘　　要：在设计参数构建摩擦副模型的基础上,运用ANSYS Workbench对制动盘结构优化设计前后的盘体表面温度分布进行仿真研究。结果表明:优化前后的两种摩擦副在紧急制动后,制动盘表面温度变化曲线均呈现先上升后下降的趋势;优化后制动盘在制动初段的温升速率显著降低。当制动至0.7 s时,优化前制动盘表面峰值温度为284.16℃、优化后降至154.3℃,峰值温度较优化前降低45.7%。摩擦副制动后,热量主要集中在制动盘与制动片接触区域(靠近制动盘边缘),其温度轮廓呈非轴对称分布。仿真结果表明,优化后散热孔加快了热量扩散速度,使得制动盘整体温升速率与峰值温度均显著降低。本研究对制动盘散热结构优化设计具有参考价值。Based on the design parameters of a constructed friction pair model,ANSYS Workbench was utilized to simulate the surface tempera-ture distribution of the brake disc before and after structural optimization.The results indicate that:For both optimized and non-optimized friction pairs,the surface temperature curves of the brake disc exhibit an initial rapid rise followed by a gradual decline after emergency braking.The optimized brake disc shows a significantly reduced temperature rise rate during the initial braking phase.At 0.7 s into braking,the peak surface temperature of the non-optimized brake disc reaches 284.16°C,while the optimized counterpart drops to 154.3°C,representing a 45.7%reduction.Post-braking,heat pri-marily concentrates in the contact area between the brake disc and pad(near the disc edge),with the temperature profile displaying a non-axisymmetric distribution.Simulation results demonstrate that the optimized heat dissipation holes accelerate heat diffusion,leading to notable reductions in both the overall temperature rise rate and peak temperature.These findings provide valuable insights for optimizing heat dissipation structures in brake discs.
