Cars Crashes with Cars of Same or Different Generation – Occupant’s Loads, Timings and Acceleration’s Effects

Abstract

Improving occupant safety is a main target of today cars designers. Known as active or passive safety, many technological solutions were developing over the time for an actual better car’s occupant safety. In the real world, in traffic accidents are often involved cars from different generations with various safety historical solutions. The main aim of these papers are to quantify the influences over the car and car’s occupants loads and vehicle accelerations in cases of same or different generation of cars involved in side car crashes. Both same and different cars generations were used for the study. Other goal of the paper was the study of in time loads conformity for occupants from both cars involved in crash. The paper’s experimental results were obtained by support of DSD, Dr. Steffan Datentechnik GmbH - Linz, Austria. The described tests were performed in full test facility of DSD Linz, in “Easter 2015 PC-Crash Seminar”.

In all crashes we obtaining results from both dummy placed in impacted and hits car. The novelty of the paper are the comparisons of data set from each of occupant (dummy) of two cars involved in each of seven experimental crashes. Another novelty of this paper consists in possibilities to analyze the influences of structural historical cars solutions over deformation and loads in each cases of traffic accidents involved. Paper’s conclusions can be future used for car designers and for passive safety improvement.
