Analysis on Vibratory Subsoiler considering slowly varying parameter

According to the analysis to the motion track of the subsoiler, the influence on the motion track caused by the vibration amplitude and vibratory frequency has been reached, the system model of the vibratory subsoiler with slowly varying parameters of the soil has been built, the asymptotic method is adopted to carry out solving and analyzing, and experimental study is done by using the vibratory subsoiler. Analysis shows that the change of soil stiffness, soil damping, and soil quality parameters makes the system resonance curve shift, and the change of vibration amplitude, vibration frequency can improve the efficiency of deep scarification of soil.
