Stress Analysis and Strength Evaluation of Pressure Swing Absorber
Based on JB/T 4732-1995(Confirmed in 2005)"Steel Pressure Vessels——Design by Analysis",the stress distribution and strength evaluation of a pressure swing absorber under design pressure and working pressure were analyzed using the finite element method.The stress analysis results show that the maximum stress of the pressure swing absorber occurs at the outside of the connection between the top tube and the head under design pressure and working pressure.The results of the linearisation strength evaluation of the stress concentration parts and cylinders of the pressure swing absorber show that the calculated values of the stress strength of the pressure swing absorber are less than the allowable limit of the stress strength under the design pressure and the working pressure and that the stress intensity requirements are met.It is recommended to carry out a reinforcement treatment at the stress concentration site to ensure the safe and stable operation of the pressure swing absorber for a long time.
