Pre-collision occupant response

Simulations in the AnyBody Modeling System can be used to predict the forces arising prior to an impact (pre-collision analysis), 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.

Examples:

  • 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:

  • Posture of human model
  • Vehicle CAD model
  • De-acceleration data

Output:

  • Muscle and joint reaction forces
  • And much more

The steps to model this can be the following

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

Models in AMMR

  • The SeatedHuman model can conceptually be used as a starting point for the model assuming no motion capture data is being used as input to the model.
  • If motion capture data is being used as input the model, the model can be based on the a mocap model: Multi trial MoCap Model
