In order to improve the safety performance of ultrahigh pressure vessel under 700 MPa pressure,the author designed a kind of ultra-high pressure container structure with carbon fiber winding.The finite element method and equivalent temperature method were used to simulate the situation of carbon fiber winding on the steel cylinder layer by layer,and the best sealing position was analyzed.The results show that the designed ultra-high pressure vessel can meet the requirements,and the flange has a great influence on the strain change of the steel cylinder.The winding design and sealing position analysiscarried out by the author provide a referencemethod for the sealing research of ultrahigh pressure equipment.
