    摘要:

    為了確定聯(lián)合整地機(jī)平整部件的關(guān)鍵參數(shù),，對(duì)其進(jìn)行田間試驗(yàn),，以作業(yè)速度,、合墑盤(pán)直徑和合墑盤(pán)偏角為影響因素,，地表10 cm內(nèi)碎土率為響應(yīng)指標(biāo),，采用3因素3水平的響應(yīng)曲面分析試驗(yàn),，并通過(guò)Design-Expert軟件建立指標(biāo)與因素之間的回歸方程,，進(jìn)行參數(shù)優(yōu)化,，得出最優(yōu)參數(shù)組合為：作業(yè)速度10.63 km/h,、合墑盤(pán)直徑450 mm,、合墑盤(pán)偏角17.71°，此時(shí)碎土率為91.92%,，符合農(nóng)藝要求,。

    Abstract:

    In order to determine the key parameters of the flattening component on combined cultivating implement, the field experiment was conducted by using the flattening device. The three factors and three levels orthogonal regressive tests were designed in the experiment with working velocity, diameter of the field-ditch filling disc, angle of the field-ditch filling disc as influence factors and the soil-breaking rate as response index. The regression mathematics models between response index and influence factors were established and the parameters were optimized through Design-Expert. The optimal combination was that working velocity of 10.63km/h, diameter of the field-ditch filling disc of 450 mm, angle of the field-ditch filling disc of 17.71°. At that time the soil-breaking rate was 91.92%, which could meet the needs of agricultural demands. 
