CAE Technology High-Accuracy Unit Assembly Modeling Technology Using the VAM Method

VAM (Virtual Assembly Model) Method: Overview

  • In the dynamic simulation model development for complicated and layered structure, the VAM （Virtual Assembly Model）technology enables accurate and systematic development of unit assembly analysis models that involve various inter-part contacts.

Benefits of This Method

  • Reduced model creation effort (no correlation identification required)
  • High-accuracy unit assembly modeling
  • High versatility
    • Database of inter-part contact characteristics
    • Can accommodate changes in unit geometry and load conditions

VAM Method Process

  • 1.
    Extract contact characteristic (stress vs. stiffness/damping) tables via simplified rig testing/analysis
  • 2.
    Contact analysis of sub assemble structure
  • 3.
    Mapping contact characteristic (stiffness and damping) according to contact stress distribution (MAT9 Updater)
  • 4.
    Frequency response analysis (linearized)
