【Abstract】 The common modules and parametric finite element model of modular vibratory bowel feeders are established. The dynamic performances of the model are explored by the use of finite element analysis software ANSYS. The vibration characteristics (natural frequencies and mode shapes) of the feeder are determined by a modal analysis. Electromagnetic force is calculated by 3D static electromagnetic field analysis. The sustained dynamic behavior of the bowel is predicted by a harmonic response analysis. Thus the overall performance is optimized by coupled-field analysis of magneto and structural. The method is verified by practice.更多还原
