Dynamic Simulation Tests on Influencing Factors of Deep Tilling Plow Working Performance
A plow surface-soil system dynamic simulation model was established, through MathCAD and ANSYS/LS-DYNA, on which the dynamic simulation tests were carried out by experimental design method. The discipline and mechanism about forming parameters of guiding curve and the plow working factors influencing on two targets, traction resistance and turn performance, were discussed and the factors optimization was made. The results show that tangent angle of guiding curve endpoints has a remarkable influence on two targets; in addition, it is benefit for reducing traction resistance and enhancing turn performance when the angle is large. Under the optimal condition, traction resistance is 4.40kN and turn performance reaches the optimal level 8.0.
