The Fatigue Life Analysis of Prestressed Wire-Wound Super-High Pressure Vessel Based on ANSYS

Abstract:

With the the development of super-high pressure technology such as the super-high biological treatment processing, the wire-wound prestressed vessel was widely used as the main pressure bearing structure. It’s proved that the stress was well-distributed along thickness direction and the carrying capacity was improved comparing with traditional pressure vessel. But the deign of wire-wound pressured vessel so far only checks out the fatigue strength margin of winding wire according to the design theory, and lacking of fatigue design of inner cylinder could causes potential safety hazard. So a stress analysis was carried out for prestressed wire-wound vessel with the help of ANSYS, and the fatigue life of the whole prestressed vessel was validated by means of theoretical calculation and the Fatigue Tool .
