摘　　要：基于ABAQUS有限元仿真软件建立制动盘摩擦副的三维模型,研究在紧急制动时不同工况下两种高体积分数SiCp/Al复合材料制动盘温度场的分布特点和变化规律,并与铸铁制动盘和锻钢制动盘的计算结果分析;将仿真与文献试验结果对比,验证仿真模型建立的准确性。结果表明:同种工况下,与铸铁和锻钢材料制动盘相比,SiCp/Al复合材料制动盘整体温度较低,温度场分布更均匀,有利于减少制动盘上热裂纹的萌生和扩展,提高制动盘的抗热衰退性。仿真结果与文献试验结果总体趋势一致,证明仿真模型可行。This paper established a three-dimensional model of brake disc friction pair based on ABAQUS finite element simulation software,and studied the distribution characteristics and variation rules of temperature field of two kinds of highvolume percent SiCp/Al composite brake discs under different conditions of emergency braking.And the calculation results were compared with those of cast iron brake disc and forged steel brake disc.The simulation results were also compared with the experimental results in relevant literature to verify the accuracy of the simulation model.The results show that the overall temperature of SiCp/Al composite brake disc is lower and the temperature field is more uniform than that of cast iron brake disc and forged steel brake disc under the same working condition,which is beneficial to reduce the initiation and propagation of thermal cracks on the brake disc and improve the thermal recession resistance of the brake disc.The simulation results were consistent with the general trend of the literature test results,so the simulation model established in this paper was feasible.
