Auxiliary Posts

Auxiliary posts may be used to include excitations other than the road surface, such as aerodynamic forces.
  1. Posts can be added or deleted using the ‘Add’ or ‘Delete’ buttons respectively.
  2. Attachments for each Auxiliary Post consist of Body and Point.
    Note:
    • An orientation joint is used between the Jack Body and the ground.
    • A ball joint is used between the Jack Body and the attachment Body.
  3. Signal Type - There are three signal types that can be used for the input to an Auxiliary Post:
    • Displacement
    • Force/Moment
    • Acceleration: Acceleration is first converted to displacement, following which the displacement is applied.
