Mechanical Analysis and Optimization of Body Structure of Compression Molding Equipment
Aiming at the problem of a certain type of composite material molding equipment with silver streak defects in the pro-duction,a simplified model of the molding equipment was first modeled using UG software and then was imported into the ABAQUS finite element software to form the molding.The structural strength of the machine's body was analyzed by finite ele-ment and compared with the experimental deformation to verify the reliability of the model.Finally the deformation of the incon-venient test position in the experiment was predicted.The results indicate that the established finite element model is reliable.The lack of strength and rigidity of the upper substrate is the main reason for the deformation and displacement of the upper substrate,which leads to the defects of molded products.The displacement distribution of the upper substrate is small on the four sides and large at the center.The maximum predicted displacement is 0.884mm,which is located at the center.The minimum displacement is 0.1174mm,which is located at the four corners.For the upper substrate four optimization schemes were proposed and compared with.It was found that increasing the thickness of the upper substrate had the most obvious effect on improving the rigidity of the device,followed by increasing the number or thickness of ribs,and the center single diagonal rib had the minor improvement.The research results can provide theoretical guidance for the design of the body structure of the forming equipment.
