Abstract: After analyzing the dynamic properties of vibrating drawing system, the loading capacity, unit energy comsumption and interfere strength of vibrated material have been put forwards as the indexes evaluating the loading effect of vibrating feeder.For both uniaxial and biaxial vibrating feeders, the optimization of operating parameters has been completed by means of the electronic computer.The results of our model tests show that the operating parameters optimized for the feeders and the formulas about them are dependable and easy to carry out.
