Abstract

The working parameters of vibratory rollers have an important effect on the compaction quality. The traditional method of obtaining the best working parameters through field tests is time-consuming and laborious. In order to determine the best working parameters more conveniently and accurately, a mechanical-hydraulic-finite element co-simulation method is proposed in this paper. This method considers the effect of the hydraulic system on vibration compaction and makes the simulation result as close to the actual condition as possible. By analyzing the change of soil stress and settlement, the effect regulation of working parameters on compaction quality is obtained. The results show that the proposed co-simulation method can accurately reflect the real conditions, and the best compaction quality can be achieved when the walking speed is 3 km/h, the vibration frequency is 24 Hz, and the amplitude is 2.5 mm. The research provides a reference for improving the compaction quality and compacting-related simulation.

土壤振动压实过程中优化工作参数选择的协同模拟

振动压路机的工作参数对压实质量有重要影响。通过现场试验获得最佳工作参数的传统方法费时费力。为了更方便、更准确地确定最佳工作参数，本文提出了一种机械-液压-有限元协同模拟方法。该方法考虑了液压系统对振动压实的影响，使模拟结果尽可能接近实际情况。通过分析土体应力和沉降的变化，得到工作参数对压实质量的影响调节。结果表明，所提出的联合模拟方法能准确反映实际情况，当行走速度为 3 km/h、振动频率为 24 Hz、振幅为 2.5 mm 时，可获得最佳压实质量。该研究为提高压实质量和压实相关模拟提供了参考。
