Abstract: In order to improve the working performance of the small agricultural machinerys forward resistance and torque, the vibrational rotary tillage force analysis was taken. Using dynamic software Lsdyna solver and ANSYS simulation settings, combined with MAT147 material model, the cutting tool of soil on the 3D dynamic simulation was investigated. Preliminary analysis shows that the numerical simulation results are reasonable, and the soil cutting process simulation is accurate and precision. The experimental results show that the vibrational rotary tillage has good effect on forward resistance and torque. It is an effective technical approach and method.
