Overview

Original co-simulation algorithm enhances stability in multibody systems, indicating improved efficiency in mechanical dynamics.

Key Points

  • To formulate an effective co-simulation approach for multibody systems that maintains stability during real-time applications.
  • Developed a co-simulation algorithm partitioning at interface nodes
  • Implemented explicit, loose coupling between subsystems
  • Retained interface mass on both partition sides
  • Exchanged inertia load contributions and constraint reactions
  • Improved algorithmic stability compared to existing methods
  • Validated effectiveness through benchmark problems
  • Demonstrated applicability in complex mechanical structures like beams and shells
  • Showed enhancement in real-time driver-in-the-loop dynamics of a race car
