Abstract
Based on the oscillation compaction mechanism, the dynamic model of ‘roller-soil’ five degrees of freedom was established after the structure of the oscillation roller was simplified. The time-amplitude response characteristics of the oscillatory compaction system under pure rolling condition was analyzed by Matlab/Simulink simulation, and the amplitude-frequency characteristics of the oscillating wheel was analyzed by the design of related tests. The results show that the horizontal vibration of the frame and the above part of the oscillating roller can not be ignored in the practical work; Considering the horizontal vibration of the frame and above. the five degrees of freedom model can better respond to the actual working condition of the oscillating roller; the amplitude frequency characteristic curve provides the theoretical basis for the continuous adjustment and intellectualization of the working parameters of the oscillating roller.
