Abstract
To improve occupant protection in side collisions, it is not
sufficient to consider only lateral structures deformation
characteristics. It is also necessary to modify frontal structures,
which are generally designed for rigid barrier frontal impacts.
In the following study, an analytical simulation model is used
to optimize lateral as well as frontal deformation structures of
passenger cars. The aim of the optimization is to minimize the risk
of injuries of passenger car occupants, considering all relevant
types of car-to-car and car-to-obstacle accidents.
Structures built according to the analytical results are likely
to show differences in their dynamic behavior compared with the
calculated characteristics. As the analytical optimization yields
optimum reduction of occupant loadings, differences of actual
structures do not lead to optimally low loadings. Restrictions have
to be considered as to what extent nonoptimal reductions in safety
can be accepted.
In full-scale tests and component tests, the performance of the
structures has to be demonstrated.
