Global-Local Workflows and High-Fidelity Stress Analysis for a Wing Flap Hinge Fitting

Presented by: Brent Lancaster, Principal Support Engineer, ESRD 
Thierry Bernard,Multi-Body & Systems Dynamics Expert, Altair

In this webinar, we analyze a part from Altair’s Aero Wing concept, the flap hinge fitting, and perform a global-local case study to provide confidence in its optimized design. This global-local workflow process may then be repeated for any other component of interest within the Aero Wing structural assembly.

Webinar Outline
Altair A&D Industry Use Case: Aero Wing concept demonstrator.

  • Multi-physics simulations to demonstrate Altair analysis capabilities.
  • Structural analysis results support optimization requirements, but a high-fidelity stress analysis may be needed to reinforce confidence in the design.
  • Flap hinge fitting is of greatest interest for the current design stage.
Altair + StressCheck Global-Local WorkFlow Process: Flap mechanism kinematic simulation structural results mapped to a flap hinge fitting high-fidelity StressCheck analysis.
  • Global forces are output from an Altair structural analysis (via Optistruct & MotionSolve) of the flap mechanism’s hinge fitting for a given design stage, load case and mesh.
  • Multiple load cases and configurations may be of interest to support the design.
  • Load case data, along with a feature-rich CAD model of the hinge fitting detail, is formatted and imported into StressCheck and applied to the CAD model boundaries for computation of local stresses in critical regions.
  • Hinge fitting stress analysis results backed up and verified by live, dynamically extracted convergence evidence to provide confidence in the optimized design.
