The effect of crashworthiness parameters on the behaviour of car-body elements

In the paper, special emphasis was put on the structural stiffness of car elements described by crashworthiness parameters. We showed how the structure parameters described by crashworthiness indicators can be calculated for various structures. The effect of crashworthiness parameters of different constructions and profiles on the relationship between the energy absorption and the maximum collision force is given. One- and multi-layer, empty and filled with different-density plastic foam elements were described. The behaviour of different elements and the effect of plastic foam density on the crashworthiness parameters were analyzed.
