Soil has elastic-plastic deformation under vibrating working condition. And the acting force between the soil and the vibrating subsoiler parts is of complication. In order to study the effect of the material acting force to the vibrating subsoiler system kinetics features, this paper establishes the vibrating subsoiler system mechanics model considering material acting force. It adopts numerical integral to answer and analyze this model and verify the correctness of the model through comparison of the simulation data and experimental data. The analysis shows that when the amplitude is between 0.01m-0.02m and the vibrating frequency is between 14Hz-16Hz, the vibrating subsoiler can have a comparatively good performance.
