基于全因子实验的激光打孔参量与吸阻关系分析

Analysis of relationship between laser drilling parameters and draw resistance based on full factorial experiment

激光打孔可以改善烟支的总通风率和吸阻等指标,满足消费者对烟支的感官质量体验。为了获得最佳的激光打孔参量组合,在吸阻指标固定的前提下,采用全因子试验方法,探究出激光打孔参量与吸阻的关系方程。结果表明,脉冲宽度较另外两个因子(功率与布孔偏量)对吸阻的影响更为显著;在3个因子同时变化一个单位的情况下,脉冲宽度对吸阻的影响最大,大约是功率和布孔偏量的10倍;为使吸阻变小,应该让3个主效应因子尽可能大;功率与布孔偏量的交互作用对于吸阻的影响相对于其它因子之间的交互效应要显著得多。该研究为吸阻的质量管控提供了统计学依据,这种试验分析问题的方法也为其它类似的试验提供了借鉴。

Laser drilling can significantly improve cigarette quality,such as total ventilation rate and draw resistance of cigarettes and satisfy consumers’sensory experience.In order to obtain the best combination of laser drilling parameters,the relationship equation between laser drilling parameters and draw resistance was explored by using full factor experiment method on the premise of the fixed absorption index.The results show that pulse width is more significant than the other two factors(power and offset hole size).When the three factors change one unit at the same time,pulse width contributes the most influence on draw resistance,about 10 times that of power and offset hole size.In order to reduce draw resistance,the three main factors should be as large as possible.The interaction between power and offset hole size is more significant than the interaction among other factors.The study provides statistical basis for quality control of draw resistance,and the method of analyzing problems also provides the reference for other similar experiments.
