The process analysis of commonly used T-shaped tube compound bulging media

As the important bearing structure of aircraft high pressure systems, the properties of air ducts are directly related to the flight safety. In order to improve air ducts formation quality and reduce the forming processing cost, improving the tube bulging processes is needed. The key technology of bulging processes is one of the choices of dielectric bulging, through to the liquid medium, plastic medium, the elastic medium, viscous medium and solid medium forming technology characteristic analysis, this study describes the advantages and disadvantages of various media.
