摘要

摘要: 为了描述纳秒激光对钛合金打孔过程中孔的形貌及温度场的变化规律，建立激光打孔的物理模型，利用ANSYS中APDL语言进行编程，对温度场进行仿真分析，并利用单元生死技术模拟孔形貌的变化过程。从有限元数值模拟和实验两方面综合分析比较了激光工艺参数(脉冲能量和脉冲数量)对打孔质量(孔深和孔径)的影响，系统论述了钛合金纳秒激光打孔的一般规律，以达到工艺参数优化，提高打孔质量的目的。

Abstract: To describe morphological changes in the drilling hole and simulate the temperature distribution during nanosecond laser drilling, a physical model of titanium nanosecond-pulsed laser drilling was established and programmed using ANSYS Parametric Design Language (APDL). Elements birth and death technology was applied to simulate the drilling process in the finite element analysis software ANSYS. Experimental and simulation results were compared, and curve changes in the laser drilling results (hole depth and diameter) together with laser machining parameters (laser energy and pulse number) were obtained and investigated. Effects of process parameters on hole quality are analyzed and compared from finite element simulation and experiment to optimize process parameters and improve hole quality. The universal law of nano-second pulsed laser drilling on titanium alloy is discussed systematically.
