Studying on spacing scattering phenomena in pulse laser machining is an important method to analyze quality of laser bean absorbed by material and improve machining precision. 对脉冲激光加工中空间散射现象的研究是分析材料吸收激光束质量,提高加工精度的重要方法。
When wire-to-plate spacing is increased, both discharge voltage and pulse peak voltage are increased, which results in the reduction of the single pulse energy input and the discharge power. 线板间距增加,放电电极起晕电压升高,脉冲电压峰值增大,脉冲电源向反应器注入的单次脉冲能量减少,放电功率降低。
The influences of the discharge voltage, the wire-to-wire spacing, the wire-to-plate spacing, and the pulse-forming capacitance on per pulse energy, secondary streamer energy and energy utilization efficiency have been investigated at atmospheric pressure. 实验研究了供电电压、反应器的线板电极配置形式(线线间距、线板间距)及脉冲成形电容等影响因素对反应器单次脉冲能量、二次流光能量及能量利用率的影响。
When the optimal wire-to-wire spacing is 0.6-1 times the wire-to-plate spacing, per pulse energy increases, and the secondary streamer energy decreases. 最佳线板配置时(线线间距为线板间距的0.6-1倍),反应器单次脉冲能量较大,二次流光能量较小,能量利用率达到最大。
