Crash Helmet Dynamics; predicting suitable designs

Friday January 3, 2014 at 10:48am
Crash helmet makers have stringent safety requirements when designing new helmets.  Often this can take many design cycles to get right; which means a lot of time and money is spent on practical testing!
SOLIDWORKS Simulation Premium can be used to cut out much of this wastage by predicting how well the design will perform in a virtual environment.  Meaning you can test many more ideas!
 The video shows an example of a bicycle helmet striking a wall at 30 mph.  It’s a Nonlinear Dynamic type study and uses a special Blatz-Ko material model for the foam core of the helmet.
Look how much the foam is squeezed during the impact!
