Assessment Approaches of Automobile Frontal Crash
This article presents three assessment approaches of automobile frontal crash
pulse by using data from the National Highway Traffic Safety Administration
(NHTSA) database (56 km/h frontal crash tests). A direct relationship between
structural characteristics and automobile safety is established in the study. In
the first approach, the crash pulse criterion is improved in the form of a
spider diagram based on the star rating. In the second approach, the crash pulse
comprehensive evaluation index (PI) is built by weighting function and
correlation analysis between pulse parameters and occupant injury risk indexes.
In the final approach, a prediction model for major occupant injury risks and
indexes which can be regard as an additional evaluation method of crash pulse
quality is built by the multiple linear regression method.
