This paper examines the influence of different model and operating parameters of an oscillation roller on the compaction effect and the response behaviour. The main objective is the validation of a recently established continuous compaction control parameter for oscillation rollers. The study is based on a numerical model of the dynamic roller–soil interacting system, in which the intergranular strain enhanced hypoplastic constitutive model is implemented to predict the achieved soil compaction more realistically. The computed drum acceleration is compared with data recorded in field tests. One result is that the roller speed has a significant effect on the soil compaction achieved. The outcomes of this study confirm that the quantities derived from the drum response are basically suitable as indicators for continuous compaction control with oscillation rollers.

压路机的压实效果和响应的参数研究

本文考察了振动辊的不同型号和运行参数对压实效果和响应性能的影响。主要目的是验证最近建立的用于振动辊的连续压实控制参数。该研究基于动力滚子-土壤相互作用系统的数值模型,其中采用了晶间应变增强的次生本构模型来更实际地预测已实现的土壤压实。将计算出的鼓加速度与现场测试中记录的数据进行比较。一个结果是辊速对获得的土壤压实度有显着影响。
