FEA and Structural Optimization of Seal Structure of a Leak-off Pipe Quick Repairing Joint

摘要

With the help of FEA software ABAQUS, the seal structure of a leak-off pipe quick repairing joint was simulated and calculated. Different parameters influencing maximum contact stress and shearing stress of sealing face were taken into account. Essential sealing conditions of the leak-off pipe quick repairing joint were simplified, and the optimal structure of seal groove was obtained by orthogonal design. The results of FEA show that the structure could satisfy the sealing requirement of fluid pressure 1.4MPa.
