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0.2 ms、光斑半径约为0.18 mm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 design method of the laser welding process is proposed. A simplified finite element simulation model for the single-fiber bidirectional optical subassembly (BOSA) is established by using the ANSYS software. The numerical simulation method of the indirect welding stress field is adopted to study the parameters which render the minimum offset under the single beam laser welding. By combining the optimized parameters, the optical power losses after welding are analyzed under different laser welding machine parameters. The results show that when the single beam laser power is 100 W, the pulse width is 0.2 ms, and the spot radius is about 0.18 mm, the optical assembly has the minimum offset and the optical power loss ratio after optimization is decreased by 7.1%.
