CAVA Safety

Calculation and visualisation of critical areas (at any time of the construction process)

CAVA Safety The direct safety of passengers and pedestrians plays an increasingly major role in the development of new vehicles. It is also approved by some "crash tests" on the real vehicle, based on regulations which are still relatively new. It is important for the designer to identify those areas which have to be checked by means of crash tests as early as possible within the CAD System. The protection of pedestrians includes the bonnet and the windscreen, and certain areas in the interior of the vehicle in the case of head impact. The size and position on these areas depends on the vehicle parameters but also on the vehicle geometry in particular. 

CAVA Safety provides the user with CAVA features, which calculate these areas and create these as CAVA geometry within CATIA. This informs the constructor of the critical areas early on in the process. 

As with all CAVA features, there is a link to the vehicle data, so the data is (automatically) updated with some modifications.

CAVA Safety Highlights:

  • Pedestrian protection
  • Calculation of required areas on engine hood (flexible tape)
  • Calculation of reference curves on bumper and fender
  • Head Impact
  • Calculation of reference target points inside the car
  • Safety Radius
  • Check for minimal curvature radius of the exterior design
  • Calculation of the specific requirements for the bumper
  • Interactive, dynamic calculation by mouse pointer
  • Specific handling for grille / lamp elements
  • Minimum Radius
  • Checking of the minimum radius of the internal vehicle geometry according 
  • Internal vehicle geometry with the explicit pendulum movement
