摘要:
在不同的工艺参数下用硬质合金麻花钻分别对碳纤维复合材料板和碳纤维复合材料板/钛合金叠层板进行钻孔,对钻孔过程用Abaqus有限元软件进行三维仿真,对比仿真和试验结果的轴向力和制孔效果。结果表明,在保证制孔的质量的前提下,选取合理的工艺参数,得到叠层材料制孔的工艺参数的优化结论。

Abstract:
The drilling process of CFRP and CFRP/Titanium stacks under various processing parmeters with twist drill was studied. And the process of drilling was simulated by using the finite element software Abaqus of 3d simulation module.Comparing critical thrust force and drilling hole quality of the simulation and test result, it shows that choose reasonable processing parameters under the premise of ensuring the quality of the hole, the optimum conclusions about processing parameters of drilling stacks materials can be obtained.
