Pressure Spray To Put The Cans Into The Discharge Port Of The Local Stress

Nozzle connections in pressure vessel heads are very popular. Stress concentration occurs at discontinous place because of structure discontinuity.It is important for the design of pressure vessels to study stress intensity of this type of structure.This paper mainly studies the feed inlet of explosion pulping equipment which is special in structure. The status of stress distribution was obtained by means of theory analysis method, finite element method and electrometric method. Firstly, theory knowledge was used to qualitatively analysis the stress of the feed inlet. The approximate tend of the stress distribution of the feed inlet was obtained. Secondly, by means of ANSYS9.0 software , the stress status of the feed inlet was analyzed in detail. Curvilinear figure of the stress distribution of the feed inlet was plotted. Finally, by means of electrometric method, the stress of the exterior surface of the feed inlet was measured. The curvilinear figure of the stress distribution of the exterior surface was drawed and compared with the results of the finite element analysis. The rationality of theory analysis and the reliability of finite element analysis were verified.
