The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...
Hydroforging is a hybrid forming operation whereby a thick tube is formed to a desired geometry by combining forging and hydroforming principles. Through this process hollow structures with high strength-to-weight ratio can be produced for applications in power transmission systems and other structural components that demands high strength-to-weight ratio. In this process, a thick tube is defor...
The hydroforming technology can realize overall forming of large storage tank’s bottom, but the quality is affected by many technological parameters. In view wrinkling and cracking defects integral bottom in hydroforming, a multi-objective optimization model established for process parameters including pre-expansion pressure, hydraulic blank holder force, fillet radius holder. Based on finite e...
For the purpose of eliminating annular welding seams in structures with differential thickness, a hydroforming method using circular 5A06 aluminum alloy plate radial thickness coupling flexible polyurethane auxiliary was proposed to form an integrated semi-ellipsoid shell. The had smaller middle and larger periphery. In forming process such plates, concentrated deformation fracture might have o...
Product design in the early stages requires a more quantitative process to ensure that simulation study's outcome will meet expectations. The purpose of this study was determine whether manufacturing software package could effectively evaluate and validate conceptualised blank tooling manufacture sizeable complex- shaped aluminium alloy aircraft panel using die sheet hydroforming. Blank tool co...
