Machine elements used for increasing passive safety of cars in dynamic loading were tested by using a Crash-Test system based on two laser transmitters with special detectors. The advantage of the method is its simplicity and a possibility to achieve high accelerations to be recorded by the contactless measuring method. The energy absorption by the car body elements of symmetrical square profiles of single and double walls (empty or filled with plastics foam) was determined. The intensity of energy dissipation by the elements applied increased with increasing the plastic foam density. The most regular deformation of elements and the highest energy dissipation was observed when plastic foam density was over 60 kg/m3. Unresonable increase in plastics foam density resulted in a decrease in plastic displacement of the elements and in significant increase of acceleration. This can decrease the safety of car users.
