摘　　要：基于土壤变形的一种塑性模式 ,提出了混沌振动压路机压实过程的动力学模型。借助计算机技术对其过程进行了数值仿真 ,探讨了不同激振频率和不同路面条件下的振动轮运动规律 ,并进行了混沌特征的识别。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.
