A Design Study in Aluminum Castings -Uplock Support                                          

Feature Design for Strength and Stiffness

  • The highest stresses in the support box occur at the joining and attachment points, where loads and moments are transferred into and out of the component.
    • The uplock support has numerous flanges, ribs, lugs, bosses, grommets, and stand-offs for strength and assembly purposes.
  • One of the benefits of casting is the design flexibility to reinforce section thickness at high stress areas where improved strength and stiffness are desired.
  • In addition, the generous fillets designed into and produced in castings reduce/eliminate the stress concentrations found at joints between sections.
