基于EDEM的带式输送机磨损优化仿真设计

Simulation Analysis of Factors Influencing Belt Wear of Belt Conveyor

针对带式输送机皮带磨损严重的问题,分析了不同挡料板的形状,利用离散元仿真技术对影响结构磨损的煤粒径大小和累计接触能的结构参数进行分析。试验结果表明:煤在下落过程中,其他参数均保持不变,煤粒径越大,对皮带的磨损越严重;而在相同粒径下,输送带在直线加曲线型挡板的作用下所受累计接触能较小,因此对皮带的磨损较小;研究结论将为矿用装备的优化设计提供理论依据与数据支撑。

For the problem of serious belt conveyor belt wear,different baffle shapes were analyzed,and the structural parameters of coal particle size size and cumulative contact energy,which affect the structural wear,were analyzed by using discrete element simulation technology.The test results show that:coal in the falling process,other parameters remain unchanged,the larger the coal particle size,the more serious the wear on the belt;and in the same particle size,the conveyor belt in the straight line plus curved baffle under the action of the cumulative contact energy is smaller,so the wear on the belt is smaller;the conclusions of the study will be for the optimization of the design of mining equipment to provide a theoretical basis and data support.
