摘要

目的

托辊作为圆管带式输送机的关键部件，其接触力大小直接决定托辊的使用寿命；而托辊间距的布置方式对输送机的稳定运行及传输效率同样至关重要。

方法

采用Abaqus软件对圆管带式输送机直线段与凸凹弧段进行离散单元法-有限单元法（Discrete Element Method-Finite Element Method

DEM-FEM）耦合仿真分析，得出不同线路上托辊接触力的分布情况，同时结合理论分析验证了模型的可行性；改变托辊间距，研究这一因素对曲线段上同一托辊组中各托辊接触力分布的影响规律，并与直线段进行对比，得出不同输送线路上托辊间距与直线段的布置差异。

结果

研究为实际工程中托辊选型及间距的调整和优化提供了有价值的参考和指导。

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.
