The stick–slip motion of the drum of four different oscillation rollers during near-surface compaction of non-cohesive soils was studied based on a lumped parameter model of the interacting oscillation roller–subsoil system. The aim of the study was to assess a novel compaction indicator for continuous compaction control with oscillation rollers, which was empirically found on the basis of field tests with a specific roller. In a comprehensive sensitivity study, the excitation frequency, the coefficient of friction at the contact between the drum and subsoil and the properties of the suspension between drum and frame were varied in order to demonstrate their impact on the drum response and thus on the compaction indicator. The results of this study essentially confirm the compaction indicator for the considered oscillation rollers for a wide range of soil stiffness. The found application limits of this value are clearly influenced by the device parameters and the operating oscillation frequency.

使用集总参数模型评估振动压路机的压实指示器

基于相互作用的振动滚子-土壤系统的集总参数模型，研究了四个不同的振动滚子的鼓在非粘性土壤近表面压实过程中的粘滑运动。这项研究的目的是评估一种新颖的压实指示器，该压实指示器用于用振动辊进行连续压实控制，该压实指示器是在对特定压辊进行现场测试的基础上凭经验发现的。在一项全面的敏感性研究中，改变了激励频率，滚筒与底土之间的接触处的摩擦系数以及滚筒与框架之间的悬架特性，以证明它们对滚筒响应以及压实指示器的影响。 。这项研究的结果从本质上确认了考虑的振动压实机在大范围土壤刚度方面的压实指标。所发现的该值的应用极限明显受到设备参数和工作振荡频率的影响。
