Assembly, analysis set-up ICS Results view ICS. Flap FE structural TCAA. Flap FE CFD TCAA. Aero-loads mapping on structural mesh

8 System Model Rigid components: command line, shaft, screws, bearings, actuators, power distribution unit Kinematics joints Dynamic connections (spring, dampers, bushings, etc.) Forces and moments Surface control definition System CAD Model Structural Assembly Flap FE structual Flap FE CFD Aero-loads mapping on structural mesh Results view

9 Structural Model Rigid components: tracks, rollers, flap inboard Surface control definition Kinematics joints Elastic connections Forces and moments Contacts btw parts Flexibility of the flap outboard CAD Model Aerodynamic forces on the flexible flap Clearance measures btw flexible flap and other rigid components Flap FE structual Flap FE CFD System Structural Assembly Aero-loads mapping on structural mesh Results view

10 Aereo Force Dataset: Nodal Force (VFOSUB) Modal Force (MFOSUB) Modal Force (MFOSUB) Aero Force Dataset Surface control definition CAD Model Flap FE structual Flap FE CFD System Structural Aero-loads mapping on structural mesh Assembly Results view

11 Assembly Model The customized buttons are into the Tool Ribbon region of the Motion SimXpert Workspace: Surface control definition System CAD Model Structural Assembly Results view Flap FE structual Flap FE CFD Aero-loads mapping on structural mesh Assembly Button: permits to load and connect the System Model and the Structure Model Maneuver Button: permits to prepare the solver (ADAMS/Solver) data for the maneuvers selected.

12 Solver Phase Manual run: The Read_Excel_Manouver action, prepares the ADAMS/Solver command files (.acf) for all the analysis defined into the Excel file. Then is possible to run, for each analysis, the standard ADAMS/Solver command. All runs: Example: C:/MSC.Software/MSC_Adams/20 10/common/mdi.bat ru-st Analisi1 Use solver.bat to run all the analysis in one time.

13 PostProcessor Import results: SimXpert standard command: File-> Import -> XML Results File, then select the proper.res file. Post processing: SimXpert standard Results tools

14 Conclusions Main benefits: Process automation, related efficiency increase and time saving Parametrization Multidisciplinary Approach Multi run capability Flow data sharing using SDM capability (Simanager)
