Model Use

The Rear Monoshock Swing Arm Suspension system can be used in Rear half vehicle or full vehicle models of a two-wheeler. The default geometry and mass approximate that of a two-wheeler scooter, but the model and data can be revised to reflect any size two wheeler.

Note:
  • The wheel body represents the mass and inertia of the tire and the rim.
  • The wheel hub body represents the mass and inertia of other rotating bodies such as a brake rotor. The wheel hub and brake rotor have no associated graphics.
  • The wheel and wheel hub parts use the Wheel center location as the center of gravity.

The image below shows the Project browser view of the systems on a fully populated front suspension model. The Rear Monoshock Swing Arm system has six “child” systems.
