Abstract
In the Institute for automobiles Zastava, the quasi-static trial for behavior of passenger car body was developed. The conditions of stroke according to ECE 33 and 32 were simulated. The results of these trials point out to the possible behavior of car body at collision. By regulations ECE 94 and 95, the conditions of homologation trials, which the vehicle must satisfy, were significantly changed. The paper presents the influences of the regulations change onto the developed investigation methodology, device construction and the behavior of the car body itself. On the basis of the results of one car body investigation, the influence of changed conditions onto the behavior of sensitive car body frameworks and car body as a whole is shown.
