Abstract: In order to increase the uniformity of vibration amplitude of vibratory wheel of vibratory roller and improve its compaction performance and handling stability, vibratory wheel polarization mathematical model was established in the condition of simulating practical compaction environment. Furthermore, based on MATLAB/Simulink, the influences of vibratory wheel center, frame center, absorber parameters on uneven amplitude were analyzed. The results show that the surface of vibratory wheel center in which the exciting force act is coincided with the center of vibratory wheel is the main factor to cause the uneven amplitude of vibratory roller, and the influences of frame center, absorber parameters on uneven amplitude are relatively small. If design and manufacture deviation is controlled strictly, the coincidence degree between vibratory wheel center and the surface of the exciting force act will be increased. Meanwhile, the phenomenon of uneven vibration amplitude of vibratory wheel will be improved.
