Opis:
In the field of automotive safety, both geometrical and energy compatibility [5] of bodyworks is one of the issues. While inducing collision of vehicles with different sizes and mass, breakdowns of “smaller” vehicle may occur. For this reason, correctly designed automobiles have elements put at the same height, which are consuming energy while confronting, both bumpers, and elements of the zone of the controlled crumple. On account of limited dimensions, vehicles cannot have an effective zone of the controlled crumple from the side. At hitting with the front part of the vehicle in the side of another vehicle, most often deep deformations of the structure of the bodywork are reached and as a result of it - serious injury of passengers which were in the vehicle. In the article reconstruction of the road event was shown, consisting in hitting with the front part of the vehicle Volkswagen Golf into the side of the vehicle Mercedes. As a result of the accident the driver of one of the vehicles died, however the driver and the passenger of the second vehicle, despite of the high speed of the vehicle, didn't sustain injuries. The analyzed case is the example of the collision of vehicles with incompatible energy structures in the place of their contact. Repeatedly, the higher stiffness of the front part of the vehicle and the zone of the controlled crumple assured safety for its passengers, with the cost of the safety of the driver of the second vehicle. During the reconstruction of the event, the method of calculation leaning against the Burg model, modified on account of the movement of one of the vehicles all over the road surface with variable mechanical properties, was applied.

Opis:
Tyre-to-road adhesion has a great influence on transmitting forces between wheels and road surface and in the consequence on the safety of automobile motion. It plays significant role in vehicle motion modelling, especially for the needs of traffic accidents reconstruction and the development of active safety systems in automobiles. Simultaneously, the knowledge about tyre-to-road adhesion is limited, especially in case of the differences between anti-slip properties of summer and winter tyres. In the paper, method of the measurement of tyre-to-road adhesion coefficient is presented. The measurement system SRT-4 consists of special dynamometer trailer, towing vehicle and test-measuring equipment. It was designed for the needs of road engineering and further developed in the Institute of Vehicles of Warsaw University of Technology. It enables to obtain adhesion characteristics, i.e. graph of adhesion coefficient as a function of wheel slip ratio. In the article, examples of tyre-toroad adhesion characteristics and velocity characteristics of peak adhesion coefficient for different types of tyres (summer, winter) in different weather conditions are presented. Differences in characteristics courses caused by tyre type and weather conditions are discussed. For instance, in case of winter tyres it was noticed that their peak value of adhesion coefficient was reached for higher values of slip ratio than it was observed for summer tyres.
