The integration of the structural analysis and design system (CAD/CAE) of the hinged beam, the key component of the six-sided top press of synthetic diamond production equipment, was studied. The mature and universal Pro/Engineer and Ansys were selected as the design system and analysis system respectively, and the two were integrated into an analytical design system of hinged beam through pre-processing and post-processing through IGES data exchange standards. The characteristic parametric modeling of the hinged beam is carried out, the finite element mechanical model is established, and the displacement, strain and stress analysis results of the hinged beam are obtained by Ansys analysis system, which provides reliable analysis data for the structural optimization design of the hinged beam.
