FINITE ELEMENT ANALYSIS OF DOUBLE WEDGE ANGLE RING FLANGE JOINT UNDER BENDING MOMENT
Industrial equipment is going to take a turn for the higher parameter and larger scale.It raise taller requirement to the reliability of the sealing structure.So,the new sealing structure has been paid more and more attention in practice.In this paper,the ABAQUS was utilized to calculate the sealing performance of novel and standard double wedge angle ring gasket joint under the bending moment.The novel double wedge angle ring gasket joint was smaller than standard one.The calculation results of novel structure were compared with standard structure under the series of bending moments.The results illustrated that under the same bending moment,the stress distribution of novel structure on the sealing surface was more uniformly than standard structure.The maximum gasket contact of novel structure was 67%larger than the standard structure.The deflection angle of the novel structure and standard structure were not more than 0.001,it was lower than the ASME standard criteria 0.3 degree.According to the JB4732,two type structures were safety under the service conditions.
