摘　　要：利用离散元方法对颗粒在振动给料机中的运动过程进行了数值研究.通过对颗粒群在给料机中的宏观运动规律以及某些具有代表性的固体颗粒运动轨迹的跟踪研究,得到了振动给料机中颗粒运动随振动参数变化的一些重要结论.The moving process of solid particles in a vibrating feeder is investigated by means of Discrete Element Method. Both the macro movement of a large quantity of particles and micro movement of some typical particles are simulated under various vibrating conditions. Some important conclusions are obtained from the computational results, which are very useful for the design and operation of vibrating feeder.
