摘　　要：翼型叶片的厚度对轴流通风机的性能具有重要的影响作用,依据叶片的厚度分布函数,选取四种不同相对厚度的翼型叶片进行离散元建模分析。结果表明,在通风机的额定流量以下工作时,以12%厚度的叶片通风机性能较好;在额定流量以上工作时,以6%厚度的叶片通风机性能较好。The thickness of the airfoil blades has an important influence on the performance of the axial flow ventilator.Based on the thickness distribution function of the blades,four airfoil blades with different relative thicknesses were selected for discrete element modelling analysis.The results show that when the ventilator works below the rated flow rate,the performance of the ventilator with 12%thickness of the blade is better;when it works above the rated flow rate,the performance of the ventilator with 6%thickness of the blade is better.
