Pre-collision occupant response
AnyBody simulations can be used to predict the forces arising prior to an impact, the forces in all muscles can be found while performing emergency braking or while bracing for impact. These muscle forces can be exported to finite element packages such as ANSYS or Abaqus and be used as a precondition/boundary condition for the simulation of a crash.
- Including the effect of muscles forces on prediction of knee, thigh, and hip injuries in Frontal Motor Vehicle Crashes
- Predicting the effects of muscle activation on knee, thigh, and hip injuries in frontal crashes using a finite-element model with muscle forces from subject testing
Examples of input and output for a model of pre-collision Input:
- Posture of human model
- Vehicle CAD model
- De-acceleration data
- Muscle and joint reaction forces
- And much more

- Import CAD vehicle / automotive environment using the AnyBody Exporter for SOLIDWORKS See AnyBody Exporter for SOLIDWORKS® | SOLIDWORKS and Making Models using SOLIDWORKS
- Specify the size of the human model
See e.g., Statistical Scaling Plugin
- Connect human model to the seat and other elements of vehicle interior/exterior using kinematic constraints see e.g.
- Define motion of remaining DOF in the human model, alternative using motion capture data to drive motion of human and environment.
- Define de-acceleration magnitude in the model.
- Define force interaction between human and interior, e.g. ensure foot contact with pedals or footrest
- Implement force response from vehicle components
- Run the model
