| Abstract: |
| In order to further improve the plough performance and analyze the factors affecting plough resistance, a plough resistance model including plough structure parameters, soil physical properties and plough working parameters was established based on the Mohr\|Coulomb soil shear theory. The tillage resistance equations of two high\|speed plough A and B were established based on the soil physical characteristics of corn field in Xinjiang. The theoretical, simulation and experimental studies on tillage resistance were carried out under different tillage width (0.35 m, 0.42 m), depth (0.255 m, 0.305 m) and tillage speed (2.22 m·s-1, 2.5 m·s-1, 2.78 m·s-1). The effects of plough structure parameters on tillage resistance were analyzed. The average error between simulation value and calculation value was 3.37%, the average error between test value and calculation value was 7.18%, and the average error between test value and simulation value was 3.71%. The plough resistance increased nonlinearly with the cutting\|edge angle. The relationship between tillage resistance and tillage depth was a cubic function. The relationship between tillage resistance and tillage speed was quadratic function. The relationship between power consumption and tillage speed was a cubic function. A reasonable safety factor was proposed. and then optimized the matching power and improved the plough and tractor power model of the best match. |
