Application of SPF/DB New Structure to Titanium Main-Load Carrying Components

Abstract:

In this paper, we proposed a new superplastic forming and diffusion bonding (SPF/DB) structure and processed validation between traditional SPF/DB four sheets structure and the new structure at the coincidence boundary conditions by FEM method. The calculation results show that the new structure can decreases the maximum stress at the joining part by 82% and decreases the maximum displacement at the aerofoil tip by 51% at the cost of the mass increases less than 20%. It induces that the new structure presents better stiffness and greater load carrying capacity than traditional ones, therefore, it could be used in titanium main load-carrying structure especially the structure which has the assembling and lose weight requirement very effectively.
