【摘要】 分析了单轴性筛（给料机）筛面物料运动情况；给出了筛面物料平动的数学模型并介绍了主要编程思想。该程序可用于不同参数下筛面物料运动情况的动态演示，对工程设计时选择合理的工作参数亦有参考价值更多还原

【Abstract】 This paper is composed of three major tasks: (1)analyze the moving state of materal on vibrating screen, (2)carry out some model equations to describe the movement of the material and (3)introduce the main programing idea about the simulation software. The program can be used to display the material moving situation on vibrating screen under differ-ent woking parameters更多还原
