Abstract

Conveying velocity of a two mass feeder is adjusted by using a frequency converter according to practical requirements. But the trough mass and the exciter are often damaged because of resonance. To resolve this problem, modal characteristics of a two mass feeder are analyzed in this paper. At first, the FEM model of the trough mass is built and analyzed by using ANSYS; correctness of the simulation results is proved by modal tests. Then modal characteristics of the two mass feeders are analyzed, the natural frequencies and the mode shapes are obtained. The results show that the fifth and seventh frequencies are closer to the working frequency and may cause large deformation of the trough mass and the exciter, which are the main reasons for the damage of the two mass feeder. Analysis results of this paper provide theoretical basis for correct use and further improvement of the two mass feeders.
