摘　　要：本文选取轴流风机流场的压强和速度与风筒导流锥角间的对应数据,采用了牛顿插值法,通过Matlab软件绘制相应的曲线,从而分析出轴流风机流场的压强和速度随风筒导流锥角的变化规律,为喷雾机风筒锥角的设计提供了一定的参考.压强曲线结果表明：风筒导流锥角在0-30°的范围内,锥角越大,风机整体压强变化越小,风机性能越可靠;速度曲线结果表明：风筒导流锥角在0-30°的范围内,锥角在7°时,风机整体速度变化越小,风机性能越稳定.In this paper,we select the corresponding data between pressure and speed of the axial flow fan flow field and duct deflector cone angle,using the Newton interpolation,and draw the curve by Matlab software to analyze the variations which are between pressure and rate of the axial flow fan flow field and duct deflector cone angle.So,it can provide some reference for the design of duct deflector cone angle.The pressure curves show that in the range of 0to 30 degrees,the bigger duct deflector cone angle is,the smaller the pressure changes of the overall fan and the more reliable the fan performance.The speed curves show that in the range of 0to 30 degrees,when the cone angle is 7degrees,the smaller speed changes of the overall fan and the more stable the fan performance is.
