| 摘要: |
| 研究灭茬深松前置式联合整地机在单一作业时的机组性能。以机组作业速度和耕深为自变量，油耗和牵引力为响应值，利用Box-Behnken试验设计原理，采用2因素5水平响应面分析方法，并利用Design-Expert软件建立数学模型，对各因素及交互作用进行分析，并对单一作业参数进行优化。结合农艺因素，优化结果为：单一深松作业，机组作业速度为3.39 km/h，深松深度340 mm时，油耗为2.72 L/km，牵引力27.65 kN；单一旋耕作业，机组作业速度为3.92 km/h，旋耕深度152 mm时，油耗为3.24 L/km，牵引力8.25 kN；单一灭茬作业，机组作业速度为3.37 km/h，灭茬深度33.41 mm时，油耗为1.35 L/km，牵引力7.8 kN；此时机组达到最佳工作状态。研究结果对于合理使用灭茬深松前置式联合整地机具有一定参考价值。 |

| Abstract: |
| In order to explore the performance of front-stubble-breaking and subsoiling combined cultivating machine and optimize its working parameters, a response surface model was established by Design-Expert software and Box-Behnken experimental design method.Speed and tiller depth were taken as independent variables and fuel consumption and traction as response in the model. The optimized working speed and tiller depth were 3.39 km/h, 340 mm, 3.92 km/h, 152 mm, 3.37 km/h and 33.41 mm respectively, and the response fuel consumption and traction power were 2.72 L/km, 27.65 kN, 3.24 L/km, 8.25 kN and 1.35 L/km, 7.8 kN respectively on the conditions of single sub-soiling part, single rotary tiller part and single stubble part respectively.The result of this research is expected to help rational use of front-stubble-breaking and front-subsoil combined cultivating machine. |
| Key words: combined cultivating machine front type single work stubble sub-soiling rotary tiller |
