| Abstract [eng] |
Old car fleets, unskilled auto mechanics and the desire to save money at the expense of safety make the road run a lot of unsafe cars. After the traffic accident, not only the trim details are straightened, but also the protective car bumper frame parts. The most common traffic accident is an impact to the front of the car. First of all, the transverse beam of the passenger car is damaged. Despite the manufacturer's recommendations, auto mechanics straighten and reinsert these elements into cars again. In most cases, nobody even contemplates how a straightened element would withstand a second impact. This investigation examines the properties of the bumper structure during re-deformation. The object of the investigation is bumper beam of the VW Passat, one of the most popular car in Lithuania. In the literature review, a static method of modeling the buffer beams was chosen, measuring the deformation dependence on the working load. |
