摘要: 为了探究摊铺机螺旋布料系统的结构参数和工作参数对沥青混合料摊铺均匀性的影响,分析了沥青混合料颗粒之间的接触关系,进行了螺旋布料器三维实体建模,提出了以质量占比离异系数Sc作为均匀性评价指标。针对不同螺径、螺距和料位系数各相关参数进行仿真,得到Sc的关系变化曲线,最后利用数字图像技术开展了摊铺均匀性工程实测结果分析。结果表明:仿真分析的摊铺均匀性规律与工程实测的均匀性规律具有较好的一致性。

Abstract: In order to explore the influence of the structural parameters and working parameters of the spiral distribution system of the paver on the uniformity of asphalt mixture paving, the contact relationship among the asphalt mixture particles was analyzed, and the three-dimensional solid modeling of the spiral distributor was carried out. The mass ratio deviation coefficient Sc was proposed to use as a uniformity evaluation index. According to the simulation of various related parameters such as different screw diameters, pitches and material level coefficients, the relationship variation curve of Sc was obtained. Finally, the actual measurement results of paving uniformity engineering were analyzed by digital image technology. The results show that the paving uniformity law of the simulation analysis and the measured uniformity law of the project have good consistency.
