    摘要:

    以切茬高度、切茬線速度和作業(yè)速度為因素,，切茬裝置切割玉米根茬的切斷效果為指標,，進行了三因素三水平正交試驗,，并用SPSS進行試驗數(shù)據(jù)分析,。結果表明切茬裝置切割玉米根茬的切割率在給定因素水平上的較優(yōu)組合是：切茬高度15mm, 切茬線速度12.385m/s, 前進速度0.8m/s,。對切茬高度做了單因素試驗,，用Origin進行數(shù)據(jù)擬合并繪圖，計算顯示在固定切茬線速度為12.385m/s,、 前進速度為0.8m/s下,，完成切茬作業(yè)的切茬高度最高值為22mm。

    Abstract:

    In order to study the cutting effects of corn stubble cutting and returning device, orthogonal experiment was conducted from three factors, including stubble cutting height, stubble cutting linear velocity and operating speed. Each factors performed three levels. The experimental data were analyzed in SPSS software. The results showed that the optimal operation combination was: stubble cutting height of 15 mm, stubble cutting linear velocity of 12.385 m/s and forward speed of 0.8 m/s in a given level. Single factor experiment was conducted on stubble cutting height. The drawing was plotted and the data was fitted by Origin software. The computation indicated the highest value of stubble cutting height for finishing stubble cutting work was 22 mm under fixed stubble cutting linear velocity of 12.385 m/s and forward speed of 0.8 m/s.
