Study on external excitation of oscillating screen system of feeding machine

In order to solve the problems of low screening efficiency and resonance in the oscillating screen system of a new type of fresh bait feeding machine, The finite element calculation model is established in hypermesh. Under the finite element analysis of the model by ABAQUS software, the deformation diagram and stress value of the model are obtained. Through the harmonic response analysis, the excitation frequency parameters of the oscillating screen system are optimized, which can effectively solve the problems of low screening efficiency and resonance.
