摘　　要：为解决包装机组烟库中烟支在流动过程中的变形、堵塞等问题,采用离散元仿真软件EDEM建立了烟支流动规律仿真处理流程,并分析了不同包装速度下烟支在烟库中的速度变化及受力分布规律。以ZB28(X6S)高速包装机组烟库为对象进行验证,结果表明:在260包/min运行速度下,烟库内烟支整体分布、下烟通道烟支分布、固定分流块下方烟支分布和弧形板处烟支流动死角的仿真结果均与上机结果吻合,EDEM仿真软件适用于烟库中烟支流动规律研究。该方法可为优化烟库结构设计和运行参数提供支持。In order to avoid the cigarette deformation and jam during cigarette moving in the hopper of a cigarette packer,the discrete element simulation software EDEM was used to establish the simulation processing flow of cigarette movement pattern and analyze the distribution of force acting on the cigarettes in the hopper at different packing speeds.The validation was carried out on a ZB28(X6 S)high-speed cigarette packer,and the results showed that at the running speed of 260 packets per min,the simulation results of cigarette distribution in the hopper,in the discharge channels,under the fixed deflectors and in the dead corner of the arc plate all well agreed with the actual states during machine running;which indicated that the EDEM simulation software was suitable for studying the movement pattern of cigarettes in the hopper.This method provides a support for optimizing the hopper design and operating parameters.
