Opis:: The aim of the article is focused on assessing the degree of end-of-life for the vehicle front suspension beam. The first stage of the problem taken was represented by a road test of the vehicle at distance expressed by 100.000 km. Following the end of the operation tests, the suspension beam was dismantled and subjected to laboratory tests. The tests demonstrated numerous beam top layer plastic deformations, which came into being as a result of the vehicle driving onto an obstacle on the roadway or onto raised road infrastructure elements. At the point of connection of the stabiliser rod to the beam, surface degradation was noted, which consisted in the considerable change of the surface profile, hardness reduction and the grey and dark brown colour. Corrosion regions and fretting wear traces were noted. Corrosion pits, scratches and material build-ups was observed. The analysis of the chemical composition of wear products demonstrated the presence of elements such as iron, oxygen, chlorine and silicon, as an effect of operational conditions.

Tytuł:: Adaptive driving beam - new concept of vehicle front - lighting

Opis:: Vehicle front-lighting is essential for road traffic sofety during night-time. It is a subject of continuous changes following the progress in technology. After the introduction of gas-discharge (xenon) light sources in 90-ties of the last century, in the recent years there were adaptive front-lighting systems (AFS) allowed to be used. This kind of front-lighting with significant complexity of functions and control, relatively limited lighting improvement and high costs, does not spread as quickly as it was predicted. For these reasons, the last two years saw automatic and adaptive driving beam offered, with electronic control based on the video camera image processing. It is done referring to the present in force, static technical requirements. But the automatic control o f these lights as well as reactions of other roads users could have wide spread implications for the night-driving comfort and safety. On one hand it should create much better road illumination, as it leads in many cases to road illumination closer to the standard driving beam, when at present the passing beam would be used. On the other hand, there is a significant risk of glaring other road users as a result of their improper recognition or erroneous activation/deactivation of these lights. It could be a result of imperfections in sensors, algorithm and devices controlling light beam changes. This could lead to lack of light reaction and glaring of improperly indentifled objects e.g. bicycles, pedestrians and to illumination deterioration in response to retro-reflectors (road signs). This paper describes most important issues concerning advantages and risks of introducing this kind of lights to the market and ways of defining requirements.

Opis:: Researches in the field of technology of modern sources of light have called for the introduction and application of a few basic hardware solutions of automatic correction systems of light beam position in the vertical and horizontal axes of a vehicle. Application of Adaptive Frontlighting Systems in motor vehicles has made it possible to adapt light parameters of head lights and fog lights to the actual situation on the road. The system ensures optimal observation conditions of a vehicle's foreground. These systems have contributed to the improvement of driving safety and comfort in the conditions of restricted visibility during fogs and precipitation. The authors of the present publication substantiate the need of introducing the solution of the foreground lighting of a vehicle, which has already proved effective for motor vehicles, taking into account the specificity of movement of a tram which is one of the main means of transport within the framework of urban public transport system. The article presents the current standardization requirements concerning head lights for the abovementioned means of transport. The results of laboratory photometric measurements for currently used optical light systems, as well as the results of simulation researches of the foreground lighting of a tram in street traffic have been demonstrated. Moreover, the article presents the analysis of potential solutions for the foreground lighting of a traction vehicle with the application of automatic system of light beam control. The proposal of a method of light beam choice taking into consideration specific movement conditions of a tram has been presented. Attention has been paid to the expected exploitation and economic effect of the application of the system for a company promoted to be used in a tram, as well as to the improvement of working conditions of a tram driver and the influence on other public transport users connected with travel safety and comfort. The publication emphasizes the merits of the proper use of already existing lighting solutions and their introduction into street traffic system of a tram. The improvement of the quality of the foreground lighting of a tram significantly increases the safety and comfort of all urban street traffic users.

Opis:: Recent progress within the area of front lighting of motor vehicles makes it possible to implement some technical solutions in other types of vehicles. High quality of front lighting is a factor required not only in motor vehicles. The article shall present the current state of front lighting of trams and qualitative analysis shall be presented of currently used light beams. The emphasis put on the quality of motor vehicle projectors, their constant development and application ofnew kinds of light sources, as well as application ofadvanced systems ofautomatic light beam direction does not translate into application ofthese solutions in tram vehicles. Safe movement of a trach vehicle is conditioned by the quality and state of its main lighting. Appropriate distribution of a light beam plays a significant role in the perception of luminous sensations from a vehicle's foreground. It ensures a proper assessment of behaviour of other road traffic participants and conditions proper visibility from a tram driver's seat. The analysis of tram line lighting shall be conducted on the basis of real photometric measurement data with the use of calculation programme having an advanced model of foreground lighting of the vehicle at its disposal. Lighting recommendations shall be presented taking into account the characteristics of light beams used in trams
