| 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. The sustained dynamic behavior of the bowel is predicted by a harmonic response analysis. Thus whether or not the designs will successfully work as desired and how to modify to optimize the feeder vibrations is verified at the stage of design. |
