Abstract:
The finite element model of a U-E-type metal sealing used between engine gas swing device and thrust chamber mating flange is established based on ABAQUS software. Using The implicit algorithm of ABAQUS standard module is adopted to solve the structural parameter of U-E- type metal sealing ring being in contact with the flange pairs, and the relation among Von Mises stress, plastic strain and contact pressure intensity when the lip compression of the main sealing and the side sealing is changed. The criteria of selecting material and designing sealing structure of U-E- type metal sealing were obtained on the basis of the above measures. The new U-E-type metal sealing produced in abiding by the design criteria has passed 37.5 MPa hydraulic pressure test and 25 MPa tightness test. The result shows the criteria is reasonable and practicable, and the sealing performance of U-E- type metal sealing ring meets the application requirements.
