摘　　要：碳纤维复合材料被广泛应用于航空航天、兵器装备等领域。对于碳纤维复合材料钻削仿真研究目前刚刚起步,轴向力影响着装配孔的质量,故针对T700型碳纤维复合材料利用ABAQUS进行钻削仿真,研究轴向力与工艺参数的变化规律。将仿真得到的轴向力与试验进行对比分析,验证仿真模型的合理性,试验值与仿真值的轴向力对比误差在15%左右。再基于最小二乘法,利用仿真钻削数据,对轴向力进行拟合,拟合出回归方程,理论值与试验值对比误差在10%左右。再对不同参数下的受压损伤应力云图进行分析后,得出在418.67 r/s下,0.83 mm/s时,分层因子最小,此时装配孔质量最好,为T700型碳纤维复合材料的钻孔工艺提供实用的指导。Carbon fiber composite materials are widely used in fields such as aerospace and defense equipment.Currently,the simulation study on drilling of carbon fiber composites is just beginning,and axial force affects the quality of assembly holes.Therefore,ABAQUS is used to simulate the drilling of T700 carbon fiber composites,and the variation law of axial force with process parameters is studied.The simulated axial force is compared with experimental data for analysis,verifying the rationality of the simulation model,with an error of about 15%between the axial force obtained from the experiment and from the simulation.Furthermore,based on the least squares method,the axial force is fitted using the simulation drilling data,and a regression equation is obtained.The theoretical axial force has an error of about 10%compared to the experiments axial force.After analyzing the shear damage stress cloud map under different parameters,it is concluded that at 418.67 r/s and 0.83 mm/s,the delamination factor is the smallest,and the assembly hole quantity is the best,which provides practical guidance for the drilling process of T700 carbon fiber composite materials.
