Abstract

For the vibration problem of the squirrel-cage cleaning machine roller under normal load, modal analysis for roller was carried out to reduce the occurrence of resonance.The paper used 3D design software Solidworks to set up 3D solid model for squirrel-cage cleaning machine roller.The finite element software Ansys workbench was used for modal analysis. The results showed that natural frequency of the first two order was 7.6931Hz and 8.3117Hz.It was greater than the vibration frequency of roller at 0.7766Hz and less than the vibration frequency of motor at 23.33Hz, thus the resonance would not occur.
