摘　　要：采用正交试验法研究木粉种类、粒径分布、粉尘浓度和点火延时对木粉爆炸强度(最大爆炸压力、最大压力上升速率和达到最大爆炸压力的时间)的影响。结果表明:木粉种类、粒径分布、粉尘浓度和点火延时对木粉最大爆炸压力存在高度显著性影响,木粉粒径分布对木粉最大爆炸压力的影响程度最大;粒径分布和点火延时对木粉最大爆炸压力上升速率存在高度显著性影响,点火延时对木粉最大爆炸压力上升速率和达到最大爆炸压力的时间的影响程度最大。对于木粉达到最大爆炸压力的时间而言,仅点火延时存在高度显著性影响。此外,4种影响因素之间的交互关系对木粉最大爆炸压力和最大爆炸压力上升速率的影响较小。The effects of wood dust species, wood dust size distribution, dust concentration and ignition delay on explosion intensity(the maximum explosion pressure, the maximum rate of pressure rise and the time of maximum explosion pressure arrival) were studied by using the orthogonal experiment. The results showed that the species of wood dust, wood dust size distribution, dust concentration and ignition delay have significant effects on the maximum explosion pressure, and the wood dust size distribution has a highly influence on the maximum explosion pressure. The wood dust size distribution and ignition delay have significant effects on the maximum rate of pressure rise of wood dust, while the influence of ignition delay on the maximum rate of pressure rise and the time of maximum explosion pressure arrival of wood dust is significant as well. For the time when the wood dust reaches the maximum explosion pressure, the ignition delay has a significant effect. Besides, the relationship among the four factors has little effect on the maximum explosion pressure and the maximum rate of pressure rise of wood dust.
