| 中文摘要: |
| 为了探究碳纤维增强复合材料（Carbon Fiber Reinforced Polymer，CFRP）与铝合金组成的叠层构件的制孔工艺加工特性，课题组采用试验分析的方法开展研究，重点考查了叠层构件界面层的表面缺陷对制孔质量的影响。通过控制制孔工艺参数（主轴转速和进给量）来控制界面层孔口温度和轴向力，从而减少界面层孔口温度和轴向力带来的制孔损伤，确定轴向力和界面层孔口温度的关系模型；在此基础上，以主轴转速和进给量为变量，以仿真数据为样本，采用BP神经网络建立轴向力、CFRP孔出口温度与制孔工艺参数之间的关系模型，确定了进给量为0.060~0.084 mm/r下主轴转速的范围。试验结果表明优化后的制孔工艺参数对界面层损伤有显著的抑制效果。 |

| In order to investigate the processing characteristics of the drilling process of the laminated components composed of Carbon Fiber Reinforced Polymer (CFRP) and aluminum alloy, the research group used the experimental analysis method to carry out the study, focusing on the influence of the surface defects of the interfacial layer of the laminated components on the quality of drillingg. The interface layer hole temperature and axial force were regulated by controlling the process parameters (spindle speed and feed rate) for drilling, thereby reduced the drilling damage caused by interface layer hole temperature and axial force,and determined the relationship model between axial force and interface layer hole temperature. Based on this analysis, using spindle speed and feed rate as variables, and simulation data as samples, a relationship model was established using BP neural network to link axial force, CFRP hole outlet temperature, and drilling process parameters. This model identified the parameter range of spindle speed for feed rates ranging from 0.060 to 0.084 mm/r. Experimental results show that the optimized drilling process parameters can significantly inhibit damage to the interface layer. |
