The subject of the graduate qualification work is: «Determination of the optimal form of seal in a coaxial pipe». The purpose of this work is to increase the pressure on the pipe walls while reducing the stress on the rings. Tasks that were solved during the study: - Build the geometry of the structure: make the dimensions parametric-Build a finite element mesh in every piece of design; - Create contact pairs; - Create boundary conditions; - Perform calculation: with the application of force; - Plot a graph of the pressure on the inner and outer walls as a function of the applied force on the plate; - Show pictures of stress distribution and characteristic elastic deformations; - Choose optimization parameters; - Choose the optimal seal shape. The work was done in the modern Ansys APDL calculation program using the finite element method. As a result, an optimal sealing shape was obtained, where the rounding radius is 1.2 mm. With such a radius, the pressure on the walls increased with a small stress increasing in the rings. The results obtained can be used at the stages of design, and operation of metal pipes in the oil industry. With such an optimal parameter, the design will be reliable and better perform its functions.
