Abstract:
In order to solve the problems about uneven amplitude of tandem vibratory roller made in China, this paper did the roller's vibration tests, analyzed the factors affecting uneven amplitude, established the polarization Matlab simulation model and put forward the solutions. The experimental results show that: if the surface of the vibratory wheel center on which the exciting force act is coincided with the centroid of vibration mass is the key factor to cause the uniformity of vibrating amplitude, the uniformity is related with the manufacturing and installating of the roller; the vibration of improved roller can be retested, when being high amplitude, the deviation of amplitude can be reduced from 7.1% to 2.9%; when being low amplitude, the deviation was reduced from 6.2% to 1.5%. 8 tabs, 9 figs, 8 refs.
