Vehicle Pedestrian Head Impact - a Computer Method for Rating a Profile Without Previous Mathematical Modelization 856110
No method based on experiments is convenient for evaluating
globally the potential risk of a given vehicle for the whole
population of pedestrians at risk, which encompasses the smallest
children and the tallest adults simultaneously, when a large range
of impact speeds has to be considered.
Mathematical models are also inadequate, due to the large number
of runs required for obtaining the probability of impact on each
section of the front end profile.
This paper describes first a recently improved mathematical
method for defining the head trajectories yielded by experimental
simulations or by a validated mathematical model. Then, a computer
program is presented that simultaneously uses this method and
statistical data concerning real accidents. The output of this
program is a distribution of the impact probabilities for a given
profile. The head impact velocities can be utilized for weighing
