(MADYMO stands for MAthematical
DYnamic MOdels. It is a software package developed by
TNO Automotive Safety Solutions (TASS) of Delft, the Netherlands.
It a leading multibody dynamics solver and frequently
used for automobile occupant safety/injury calculations
for many years.)
This video was taken
from a crash simulation program used to analyze the effects
of a collision where a car wasn't equipped with airbags
and collided with a concrete barrier. The simulation shows
the violent effects of the car's impact to a front seat
passenger. After the incident the passenger was thought
to only have broken a few bones. Unfortunately, severe internal
injury to the neck was not discovered until it was too late.
If the vehicle had been equipped with airbags these injuries
would have been reduced or eliminated by reducing the stress
to the body by the seatbelts acting alone.
