摘要 为了研究各种因素作用对开沟机作业功耗的影响规律,并实现对开沟机作业功耗的优化设计,根据传统经验和已有研究结果,对影响开沟作业功耗的主要因素——开沟深度、前进速度和土壤坚实度进行设计并实施了正交试验,再根据试验结果进行了影响作用的极差分析和方差分析,得出各个因素影响的主次顺序依次为:开沟深度>土壤坚实度>前进速度,根据正交试验结果,采用二阶响应面法建立了开沟机作业功耗的优化模型,并将实测试验数据代入到模型中,从而在试验中加以计算验证.试验结果表明:功耗响应面模型的计算值与试验值的误差在10%以内,这说明建立的功耗优化模型具有较高的工程实用性,可为开沟机产品设计人员选择节省功耗的参数组合和操作人员选择功耗匹配的拖拉机提供理论依据.

Abstract: In order to study the influence of factors involved on ditchers operation power consumption and realize the optimization design,the rang analysis and the variance analysis for ditching depth,forward speed and soil hardness were conducted by the design method of orthogonal experiment. It is concluded that the factors sequence is: ditch depth>soil hardness>forward speed,the second order response surface optimization model was established according to the results of orthogonal experiment. Actual measured test data were agree with the model,so the model was validated by the experiment. The experimental results show that the error between calculated and experimental values is within 10%,which indicates that the power consumption optimization model has high engineering practicability. Therefore,the response surface optimization model of ditcher power consumption proposed could provide the theoretical basis for the product designers to select economic power consumption parameters and the suitable power tractor.
