摘要
通过建立振荡压路机的单自由度系统振动模型，对振荡压路机的动态响应进行了定性分析，建立了土壤的动作用力以及荡幅的数学表达式，然后利用有限单元法研究了土的压实过程及其在压实过程中的应力状态，并由此分析振荡压实的特点与适用范围。
The dynamic responses of oscillatory roller are analyzed qualitatively through setting up the single degree of freedom vibratory model for the roller, the effect on soil and oscillating amplitude equation are set up. The compaction and stress state are studied through finite element method, and the compaction characteristics and applied scope are given.
