摘要
飞秒激光精微修正技术是采用具有高能量密度的超短脉宽激光对面齿轮齿面进行精微加工的一种新型加工方法。考虑到齿轮材料成分间互温感应，建立了飞秒激光烧蚀面齿轮材料动能量热模型，仿真分析了飞秒激光修正面齿轮齿面温度场的变化规律，发现随着激光能量密度的增大，电子温度急剧升高，电子温度远大于晶格温度，烧蚀凹坑的深度和直径均增大。实验中观测到烧蚀凹坑的齿面形貌，证实了动能量热模型的正确性，为飞秒激光精微烧蚀面齿轮的研究提供理论指导。
Abstract
Femtosecond laser microcorrection technology is a new type of processing method that uses a laser with ultrashort pulse-width and high energy density to micromachine the gear tooth surface. Considering the mutual temperature induction between the components of the gear material, a kinetic energy thermal model of the femtosecond laser-ablated surface gear material was established, and the evolution of the temperature field of the tooth surface of the femtosecond laser-modified surface gear was simulated and analyzed. The temperature of electrons rises sharply and is much greater than the lattice temperature and the depth and diameter of ablation pits increase. The tooth surface morphology of the ablated pits was experimentally observed, confirming the correctness of the kinetic energy thermal model, and providing theoretical guidance for the study of femtosecond laser-ablated surface gears.
