The Structural Dynamical Buckling Analysis for a Novel Vacuum Autoclave under the Extreme Operating Conditions

Abstract

The elastic buckling load is physically important in design of the pressure vessel with shell framework because it is actually the critical step in a thin-walled shell configuration that will eventually lead to complete failure. An finite element model of vacuum autoclave was established and the buckling load calculations under the extreme operating conditons have been carried out to obtain the modal deformation condition and the safety factor. The results showed that the structure has a higher safety factor, which indicated that the vacuum autoclave design can meet the working conditon requirements.
