Impacts Wide Paver Screed Conveyor of Speed on Dosing Quality

Jiang Wan;Zhu Zhendong;Southeast University;XCMG Construction Machinery Co.,Ltd.;  
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.
