Stress analysis study of pressure vessel tube sheets

Stress analysis of pressure vessel tube sheets is crucial for ensuring the safe operation of the equipment. As a core component connecting the heat exchange tubes to the shell, the tube sheet is subjected to the combined effects of internal pressure, temperature fluctuations, and external loads. Finite element analysis and other methods are necessary to evaluate its stress distribution and strength.

The analysis must consider material properties, boundary conditions, and load combinations, such as pressure cycles and thermal stresses, to identify high-stress regions and potential fatigue risks. The research results guide design optimization, such as adjusting the structure or materials, thereby improving the load-bearing capacity and service life of the tube sheet and preventing failure accidents.
