摘要
由于激光与材料相互作用的复杂性,使得小孔加工质量很难控制。根据激光打孔的特点与实际加工环境建立激光打孔的热力学模型,利用有限元分析软件ANSYS对激光打孔过程的温度场进行模拟仿真,通过对温度场的分析,得到小孔的孔深、孔径的时间特性以及随激光能量的变化曲线,为实际打孔之前选择最优打孔参数提供参考。
The machining quality of the hole is difficult to control because of the interactional complexity between laser and material. A thermodynamics model was established based on the characteristic of laser drilling and factual machining environment. The finite element software ANSYS was used to simulate the laser drilling process. The time characteristic of the depth of the hole and its aperture, and the changing curve with laser energy were obtained to provide references for choosing the best drilling before actual drilling by the analysis of temperature field.
