COMPARISON OF WEIGHT AND DIMENSIONAL PARAMETERS OF THE PASSENGER CAR FLEET OF UKRAINE IN THE CONTEXT OF A SIDE IMPACT
DOI: 10.33868/0365-8392-2025-1-282-23-28
Abstract. Currently, there is no single classification of car classes in the world. The European car classification system has 12 classes, in the USA there are 7 classes, the European Committee for Independent Crash Testing EuroNCAP divides cars into 9 classes. In each classification there is a class of cars SUV (sport utility vehicle) – sports utility vehicles, which are in demand in the new car market. The Ukrainian market did not stay away from this trend. Currently, approximately 40% of the new car market sold in Ukraine is SUV class vehicles. Considering the mass and dimensions of these vehicles in comparison with conventional passenger cars, the question arises of the correspondence of the mass and dimensions of the trolley with which the side impact is simulated by organizations conducting independent crash tests. Having analyzed the features of conducting side crash tests, we can see that the cart that simulates a side impact of a car has the mass dimensions of an average passenger car. That is, crash tests simulate a collision between two passenger cars. Experts predict that by 2035 the world’s car fleet will reach 2 billion cars. This trend inevitably leads to an increase in road accidents. During independent crash tests that check the side safety of the driver and passengers, the impact energy is distributed and absorbed by the side sills, door pillars and safety bars located inside the doors. Unfortunately, there are no types of crash tests between cars of different mass and dimensions, for example, when a passenger car is hit from the side by an SUV. The main problem is that the height of the crossbar with crash boxes in an SUV is higher than the safety bars in the doors of a passenger car. Thus, it is difficult to predict the distribution of kinetic energy of the impact and the severity of injury to the driver and passengers of a passenger vehicle.
Keywords: side impact, crash test, vehicle fleet, mass and dimensions, passive safety.
