Abstract：[Objective]As a key component of the round pipe belt conveyor,the contact force of the roller directly determines the service life,and the arrangement of the roller spacing is equally very important for the stable operation and transmission efficiency of the conveyor.[Methods]Abaqus software was used to carry out DEM-FEM coupling simulation analysis on straight section and convex and concave arc sections of round pipe belt conveyor,the distribution of roller contact force along different lines was obtained,and the feasibility of the model was verified through theoretical analysis.By changing the roller spacing,the influence of this factor on the contact force distribution of each roller in the same roller group on the curve section was studied,and by comparing with the straight section,the difference of the roller spacing on different conveyor lines was obtained.[Results]The study provides valuable reference and guidance for the adjustment and optimization of the roller selection and spacing in practical engineering.
