The finite element model for pressing machine frame was created by ANSYS Workbench software. The statics analysis was completed. The gold driven optimization was applied for optimization design processing to reduce the mass of frame.The statics analysis results indicated that some local stress concentration was found in the chamfer position of frame in original design. The maximum stress in the frame was 156.2 MPa,which was lower than permissible stress of the selected material( 196 MPa). The displacement i...
