Simulation Analysis and Test Validation of Reverse Rotary Tiller Operation Power Consumption
摘要
Abstract
In response to the problem of high power consumption during Cyperus esculentus harvest,a reverse rotary tiller was designed.The structural parameters of the main working components of the rotary wool knife and the main composi-tion of the operating power consumption of the rotary slide were clarified.The soil-plants-spiral tool interaction discrete dollar simulation model was established to perform a reverse rotary tiller power simulation test.An orthogonal test was de-signed with power consumption as the test indicator.The speed,advancement speed,and work depth are experimental factors.Data analysis is performed by Design-Expert 10.0.1,resulting in the best working parameters of the spiral knife.The optimal job parameter is a spindle speed of 233r/min.The advancement speed is 0.65m/s,the working depth is 138mm,and the power consumption is 30.49 kW.The field test verification is verified.The relative error of theoretical and experimental values is 4.22%,proving that the power consumption mathematical model is highly applica-ble.In this study,the consumption simulation results and optimal job parameters can provide a reference for spiral mining and reduction definition.关键词
