“…* Corresponding author. Email: gernot.woitsch@tugraz.at Several investigations have been performed to solve this problem facing the longitudinal crash pulse [2,10,11,13]. A further idea is not only to shape the crash pulse in a beneficial way, which is a hard acceleration peak at the beginning of the crash followed by a low and constant level [11], but also to shape motion proportions perpendicular to the crash direction like pitching by changes to the front structure design [5,3].…”

Vehicle safety has become a major task in the development process of passenger vehicles. Measures for occupant safety are developed by reference to different tests including legal tests and consumer tests. The different load cases for the considered frontal crash tests cause different vehicle kinematics involving all six degrees of freedom. Besides restraint systems, vehicle kinematics shows distinct influence on occupant loading. A sensitivity analysis of the dummy responses due to varied motion fractions has been performed by finite elements simulations of a well-validated simulation model. The influences of particular motion components are determined by objective assessment variables. These are well-known injury criteria as well as geometrical criteria such as distances between dummy and interior. The results of this sensitivity study can be used for additional measures in terms of occupant protection.

“…And it is also one of the major factors affecting occupant injury response. Thus it is frequently used as an input parameter that stands for the real crash environment in safety simulation and vehicle crash simulator test [1][2][3][4][5][6] . However, the crash pulses derived from actual vehicle crash tests are very complicated in shape, acceleration peak, time duration and so on.…”

Crash pulse is an important parameter that can directly reflect the process of vehicle crash. And it is found that there exists an interrelationship between crash pulses and injuries of occupants. In this paper, a method of crash pulse modeling named TESW was adopted to simplify the real crash pulse with several characteristic parameters and then 37 groups characteristic parameters were obtained from 37 crash pulses of full-scale frontal tests, subsequently correlation analysis of crash pulse of body and injury of occupant were performed. And several rules that how these characteristic parameters correlate injuries of occupants were summarized.
