Analysis of Vacuum Chamber Structure Based on Visual Finite Element Modeling

Abstract

The feasibility of improving the vacuum chamber structure of vacuum packaging machine is discussed. The finite element software, Visual Environment, is used to simulate the structures of prime vacuum chamber and improved vacuum chamber which is built most through weld process. The results show that the maximum weld residual stress of the improved vacuum chamber changes and the stress concentration is greatly reduced with finite element analysis (FEA). At the same time, a path for a particular site is created and the range of stress changes is found from the original 270–340 to 240–310 MPa. The improved method not only saves resources but also improves product quality, which is verified by the actual product.
