In this paper , the mechanics model and computer control method for electromagnetism vibration feeder are studied . the emphases are put on the seeking of optical motion states and the realization of these states by computer control . using labview ( laboratory virtual instrument engineering workbench ) , a waveform generator is established to control the electromagnetic force 本文对电磁振动给料机的力学模型与计算机控制做了比较深入的分析和研究，特别是给料机的力学分析与最佳运动状态、电磁铁的一些特性和用labview实现计算机控制，在与传统的控制方法对照的情况下，建立了对比较周全的力学模型，提出了利用labview程序产生一个波形发生器，经过放大后对电磁铁进行控制。
Vibrates the feeding engine in the production process , may massive , the granulated material from store in the bunker even , fixed time , to give continuously is expected in the installment , may evenly feed the material continuously in the sand and crushed stone production line for the stave machinery , and carries on the coarse fraction to the material , vibrates the feeding engine widely to use in professions and so on metallurgy , coal mine , dressing , building materials , chemical industry , grinding compound stave , in the screening combination plant 振动给料机在生产流程中，可把块状、颗粒状物料从贮料仓中均匀、定时、连续地给到受料装置中去，在砂石生产线中可为破碎机械连续均匀地喂料，并对物料进行粗筛分，振动给料机广泛用于冶金、煤矿、选矿、建材、化工、磨料等行业的破碎、筛分联合设备中
