【摘要】：提出了一套系统的激光焊接工艺设计方法,运用ANSYS软件对单纤双向光组件(BOSA)建立了一种简化有限元仿真模型,采用间接焊接应力场的数值模拟方法,研究了单光束激光焊接下的最小偏移参数。结合优化后的参数分析了不同激光焊接机参数下焊后光功率的损失情况。结果表明,当单光束激光功率为100 W、脉冲宽度为0.2ms、光斑半径约为0.18mm时,光组件具有最小偏移,优化后光功率损失比降低了7.1%。
[Abstract]:A systematic method of laser welding process design is presented. A simplified finite element simulation model is established by using ANSYS software for a single fiber bidirectional optical assembly, and the numerical simulation method of indirect welding stress field is adopted. The minimum migration parameters of single beam laser welding are studied. Combined with the optimized parameters, the loss of laser power after welding under different parameters of laser welding machine is analyzed. The results show that when the single beam laser power is 100W, the pulse width is 0.2ms, and the spot radius is about 0.18mm, the optical module has the minimum deviation, and the optical power loss ratio is reduced by 7.1 parts after the optimization.
