Moose Model
This dummy model is developed for the evaluation of the crash-worthiness of new cars regarding moose crash accidents. A physical moose crash dummy has been developed by the Swedish National Road and Transport Research Institute (VTI).
The body and legs are modeled by solid elements using rubber material (Mooney Rivlin rubber). The body is held together by two wires connected to two rigid end plates. The legs are attached to rigid steel plates inside the body. Wires go through each of the four legs and are held in place with a rigid steel cup. All wires are modeled by beam elements.
