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。
