Numerical Analysis on Delta-Ring Seal Structure of Ultra High Pressure Vessel Employed in Food Processing

Abstract:

Due to the characters of the ultra high pressure vessel employed in food processing, a seal structure was introduced in this study. Then numerical analysis was performed using the larger finite element stress analysis software ansys12.0 for the stresses of the seal structure under internal pressure. In order to solve the contact question of delta-ring seal structure by using face-face contact model, a 3-D axisymmetric solid element was employed to calculate the stresses of the connected location among delta-ring, blind cover and end cylinder, the mises stresses in this structure were analyzed. Thus, the distribution nephograms of the stress on the contact surface were obtained in different conditions. Full-field plastic deformation of seal structure was generated when the inner pressure was larger than 300Mpa. At last, the reason for residual deformation was analyzed.
