【摘要】：采用理论推导和试验数据统计分析相结合方法,建立宽幅摊铺机螺旋布料器变径变螺距的数学模型,基于数理统计学对模型参数进行优化,并结合某一型号摊铺机给出螺旋布料器优化设计的工程应用实例;在实体工程进行足尺试验,采用无损检测和常规检测2种方法检测混合料的均匀性。试验结果表明:变径变螺距螺旋布料器的抗离析功能要优于等径等距螺旋布料器,可以很好地改善路面的离析状况。
[Abstract]:By combining theoretical derivation and statistical analysis of test data, the mathematical model of variable diameter and pitch of spiral distributor of wide spread paver is established, and the parameters of the model are optimized based on mathematical statistics. Combined with a certain type of paver, an engineering application example of optimal design of spiral distributor is given, and a full-scale test of solid engineering is carried out, and two methods of nondestructive testing and routine testing are used to detect the uniformity of mixture. The experimental results show that the anti-segregation function of the variable diameter variable pitch spiral feeder is better than that of the equal diameter and equal distance spiral feeder, which can improve the segregation condition of road surface.
