Article Preview

The mechanics properties and improved structure design for an advanced typical aviation pipe connection fit based on contact FEA and ANSYS have been researched in this paper. First of all, by establishing a multi-body contact FEM for a connection fit, its contact mechanics properties and the simulation method of pretension torque are discussed. Then the mechanics properties and stress distribution in working condition for the original connection fit are calculated and analyzed. In the end, in view of the deficiency of stress concentration in the original design, the structure improvement has been discussed and fixed on, and at the same time the stress analysis for the improved connection fit is carried out. The study has shown that as an effective means to design a pipe connection fit and analyze its mechanics, the simulation method of multi-body contact FEA given in the paper can be used to analyze effectively the mechanics properties, and the structure improvement to the original connection fit can effectively get a better load properties and enhance its reliability.
