| Abstract: | A dynamic model for"frame drum soil" system of chaotic vibratory roller was built up. The numerical simulation of the processes was finished by the computer technology. The purpose of the discussion is to try to find out the vibration rulers of the drum for different frequencies and roads. The chaos identification of the vibration drum was finished. The new phenomenons discovered in this work is very valuable in design of chaotic vibratory roller. |
