Dynamic Analysis and Experimental Research of Vibratory Subsoiler System

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. In order to research the relationship among the vibration frequency, forward velocity and tractive resistance of tractor in the farming process, the paper regards 1SZ-160 tillage implement as the research object, uses the in-house designed Π-shaped frame force measuring system to test the tractive resistance in different vibration frequencies and forward velocities, and obtains the vibration data of the base of the tractor by the vibration test system. The test result shows that in the identical vibration working condition and with the increase of the forward velocity, the tractive resistance is increased slowly, in the working condition of having the stated forward velocity and with the increase of the vibration frequency, the tractive resistance is increased fast. The tractive resistance will be affected by both forward velocity and vibration frequency, but the effect for the tractive resistance by the former is small relatively. The research result provides the reference basis for the structure design of the agricultural mechanical system.
