摘　　要：针对目前我国宽幅摊铺机在工作时由于螺旋分料器沿宽度方向上下料量分布不均匀,导致摊铺机不能连续工作,摊铺效率低下的现状,建立了螺旋分料器的仿真模型。提出了通过评价每个螺距横截面质量流量来研究螺旋轴转速对径向下料量影响的方法,同时建立了螺旋轴转速、摊铺机前进速度和刮料板速度模型,实现三者的有效匹配,从而改善分料质量,提高路面摊铺的效率。At present,due to the uneven distribution of feeding amount across the width from spiral distributor,the Chinese wide paver could not work continuously and resulted in paving with low efficiency.Considering the unevenness of distribution in the required width,this paper established the modeling and simulation,and proposed an approach which might reflect the influences of the screw shaft rotational speed on the feeding amount across the width by evaluating the mass flow of the cross sections.Meanwhile,the paper established the models of the paver＇s advancing speed,the scraper plate speed and the screw speed,and achieved the effective matching,so as to improve the dosing quality and the efficiency of paving.
