【摘要】 本文在分析振动压实过程中土体——机械系统的动力学和运动学特征的基础上,建立了接地振压和跳振压实两种工况的动力学理论模型,提出了动态振压力和跳振压实等概念。通过分析和计算,本文在振动压路机振动参数的选取等方面得到了一些有实际意义的结论。更多还原

【Abstract】 On the basis of analysis of kinematic and dynamic characteristies of a soil-machine system in vibratary compoction, two dynamic mathematical models discribing the system in steady and pulsating vibratory compaction are developed. Some concepts, such as dynamic compacting force, are introduced. Through analysis and computation, some valuable conclusions regarding the choice of vibratory parameters of a roller are drawn.更多还原
