The work aims to research the actual working conditions of high-speed auger screw to determine its structural design parameters by analyzing the design requirements of high-speed auger screw. The 3D geometric model established by the Solidworks 3D modeling software was imported into ANSYS Workbench (finite element analysis software). Moreover, its static analysis and modal analysis were separately conducted. Through the simulation analysis and optimization, the quality, total deformation and equivalent stress of the high-speed auger screw were all reduced by more than 10%. Based on the simulation analysis and optimization of the actual working conditions of the high-speed auger screw, the parameters, such as the material, inner diameter and rotational speed of the high-speed auger screw, are determined.
