STUDY ON TILLAGE RESISTANCE AND ENERGY CONSUMPTION OF A PLAIN STRAIGHT ROTARY BLADE FOR STRIP TILLAGE

The issue of reducing tillage resistance and lowering energy consumption has become increasingly relevant. Strip a positive impact on soil protection reduction. This study analysed the components rotary blades their relationship with operating parameters developed mathematical between (power fuel consumption). We summarised into three parts: air resistance, lateral rotational friction (divided horizontal vertical resistance), shear force. By theoretical analysis coupled simulation tests 11 (DEM-CFD), we obtained an friction, force 0.0883 N, 97.21 893.496 respectively, accounting for 0.01%, 9.81%, 90.18% resistance. Meanwhile, found that decreased linearly increase angular speed, which was opposite Horizontal increased in contact area. Shear significantly speed. Fuel field test power formed to build correspondence point, torque, established.
