Finite Element Analysis In Nonlinear Problems And Application Research For The Vacuum Clamp

It is significant in the static analysis of vacuum clamp by the application of Computer Aided Engineering technologies, which can make the press production more cost-effective, faster, and improve the quality and reliability of products as well. The static analysis and structural optimization of the key seal parts and components of vacuum clamp are researched in this thesis using finite element analysis software ANSYS.Firstly, by introducing the characteristics of vacuum clamp structure, the 3D-FEM frames of vacuum clamp is built-up using Parametric Design Language. The hyperelastic seal component and the composite parts are simulated based on block elements and shell elements .The distribution of stress and displacement is also presented after the hyperelasticity and contact analysis.Following the theory analysis of the vacuum seal structure on the frame, taking thickness and width of the hermetic trough as design variables, optimum design is carried out. The compare and analysis of the different ring seal structures are also studied in the thesis .Finally, aiming at the thin-wall composite material parts, the sealing performance and sections stress are analyzed for different parts. The results validates the clamp dependability and process procedure .With the finite element analysis, the results have a great significance to improve the design quality and benefit. So it has practical application value.
