High Speed Multibody Dynamic Simulation and Its Impact on Man-Machine Systems

Emerging recursive formulations for multibody dynamic simulation are outlined and shown to provide the basis for real-time dynamic simulation using parallel computers. Computer architecture considerations are examined and shown to be more suitable for implementation on shared-supercomputers. Advances in computer graphics and motion generation for operator-in-the-loop simulation, coming primarily from the field of flight simulation, are outlined. Finally, advanced ground vehicle driving simulator applications that are enabling a new class of human factors research and the emerging ability to tune the design of vehicles to the capability of the driver are summarized.
