| 摘 要： | 借助于土壤变形的一种塑性模式，提出了一种振动压路机压实过程的非线性动力学模型。在此基础上，借助计算机技术，探讨了振动压实中机架与振动轮的运动规律，并对激振力减少、土壤刚度变大和塑性变形增大等情况进行了仿真研究，发现了一些对压路机设计有参考价值的新现象

| Abstract: | A model of nonlinear dynamics for a vibratory roller in working course with one kind of plastic deformation of compacting earth is put forward,and using simulation technique on the model,the laws governing the motion of a vibrating wheel and its supporter under different simulations such as different exciting forces,earth stiffness and plastic deformation are studied and some new phenomenon are found,which are helpful for the related fields. |
