Overview:

The LandingGear model can be used to demonstrate:

  • OptiStruct flexible bodies in MotionSolve
  • Flexible translational joint in MotionSolve
  • Linear analysis, FRFs and CPSDs in MotionSolve
  • Hydraulics actuation in TwinActivate
  • MotionSolve cosimulation in TwinActivate
  • TwinActivate hydraulics actuation in MotionSolve
  • Tire Python subroutine extension in MotionSolve
  • Durability road event in MotionSolve
  • Drop test simulation in MotionSolve

WARNING : example capabilities documentation is still work-in-progress:

Pre-Requisite:

MD_Tools for Compose extension must be installed.

Usage/Installation Instructions:

Download/unpack attached files:

MD_Plugin_v2024_x_demos_LandingGear.zip

and save it as new "MD_Plugin/Mdt4Compose/Demos/Mdt4Compose/LandingGear" subfolder on top of existing MD_Plugin installation.

Initialize "LandingGear" example files:

  1. Open "MD_Plugin/Mdt4Compose/Demos/Mdt4Compose/LandingGear" folder.
  2. Define new Windows desktop shortcut to local "__GO.omd" Compose distributable.
  3. Rename new Windows shortcut as "LandingGear" and double-pick it.
  4. Wait for related OptiStruct and MotionSolve jobs to complete…
  5. Review the new content of local "_9_Results" subfolder.

Leverage dedicated DigitalTwin Driver GUI:

  1. Double-pick "LandingGear" Windows shortcut.
  2. Wait for dedicated GUI to be fully available (a few seconds to scan model file and rebuild related plots).
  3. Hit F2 key to open dedicated PDF on-line help document describing main capabilities (to be updated later).
  4. Review "Model simulation" tabs to understand the content and scope.
  5. Leverage "Model simulation - Select action : MotionView model" to explain flexible mechanism.
    1. MotionView model configuration is fully driven by "Model - param - Analysis mode" dataset member
  6. Leverage "Model simulation - Select action : HyperMesh model" to explain flexible components.
  7. Leverage "Model simulation - Select action : TwinActivate model" to explain hydraulics actuation.

Release Version: v2024.x
