摘　　要：利用计算流体力学(CFD)方法,在验证计算模型的基础上,对钉盘磨两圈齿钉所受的阻力矩进行研究.以钉盘磨主要结构参数和操作参数为试验因素,以两圈齿钉所受阻力矩为试验指标,对钉盘磨进行了正交试验,并采用极差分析和方差分析的方法对各参数对阻力矩影响程度进行分析.结果表明:对第一圈齿钉所受阻力矩影响的显著性依次为第一圈齿钉的转速>入口速度>径向间隙>齿钉间的角度;对第二圈齿钉所受阻力矩影响的显著性依次为第二圈齿钉的转速>径向间隙,其余因素的影响均不显著.研究结果为钉盘磨的设计提供了参考.In order to analyze the effect of structural parameters and operating parameters on the drag moment of pin mill,the computational fluid dynamics （CFD） method was applied in the research.The drag moment of pins at two circles was studied based on the validation of computational model.The research was carried out with orthogonal test method,where the key structural parameters were considered.The impact of key structural parameters on drag moment was analyzed using range analysis and variance analysis.The result showed that the effect order of parameters on pins＇ drag moment at the first circle was rotary speed of the first circle＞ inlet velocity＞ radial clearance＞ angle between two adjacent pins.For the second circle,the order was rotary speed of the second circle＞ radial clearance,and the impact of other parameters could be ignored.It provides reference for the design of pin mill.
