MATHEMATICAL MODELING OF OCCUPANT BIOMECHANICAL STRESS OCCURRING DURING A SIDE IMPACT
Using a simple mathematical model the injury risk to occupants of a laterally impacted passenger car may be calculated as a function of front and side structure rigidity of the vehicles involved, and the possibilities of compatible structure combinations derived. Test results show that at a given impact velocity and a given mass ratio, a favorable combination of rigidity of side and front structure may reduce the risk of injury to the occupants to far below that of the original structure combination; padding of the side structure also reduces the risk, independent of all rigidity combinations. A "two-stage" characteristic of the front structure of a passenger car improves the possibility of a favorable adaptation to the side impact; for frontal crashes, however, it does have some unfavorable consequences. Statistical evaluations have shown that dummies must be used while testing data in lateral tests.
