Opis:: The road safety is affected by several factors quality of infrastructure, behaviour of drivers, including their proper training and also safe cars. For the safety of vehicles in the approving process a number of regulations (regulatory acts) apply, regulating the technical requirements in the active and passive vehicle safety, but also in the environment. In the area of technical requirements for vehicles and their parts significant changes occur constantly, mainly due the progressive technological developments. A large number of regulatory acts are often changed due to the tightening. These regulatory acts relates directly to manufacturers, because their manufactured vehicles have to meet these requirements. That these regulatory instruments are evolving in the right direction proved the fact that due to better road safety the number of fatal accidents in the last two decades shrunk, although the volume of traffic has tripled. A significant progress has been achieved only through the improved vehicle safety and only in a small measure thanks to the improvement and upgrading of the infrastructure.

Opis:: The paper presents the results of the conducted tests of torsional stiffness of the VOSCO S106 passenger car, as well as the validation process of these tests by means of numerical analyzes using the FEM finite element method. The most important element of the vehicle structure is the part of the spatial frame or the safety cage. Engine, brake system, fuel system and steering system, suspension as well as body and parts, their mounting nodes, hinges, locks, etc. are attached to the frame. The frame must therefore have adequate strength to protect the driver in the event of a tipover or impact. The frame is usually made of steel pipes with the prescribed dimensions and strength according to regulations. The torsional stiffness of the vehicle chassis has a significant influence on its driveability and therefore is an important parameter to measure. In this article, the torsional stiffness of the vehicle frame is calculated experimentally, which was then verified by finite element analysis (FEM) using the Altair HyperWorks program.

Opis:: Increasingly stringent environmental protection requirements and the implementation of the most modern technologies compel automotive manufacturers to develop the production of environment-friendly vehicles with electric drive systems. In difficult road conditions, vehicle participants are exposed to various hazards, especially to health and life. This forced the Automotive Industry Institute (PIMOT) to attack the important problem named “Electric Vehicles’ Operational Safety (EVOS)”, which is related to a number of new issues, not sufficiently explored yet. The tests carried out until now on electric vehicles to check their conformity with the Regulations and Directives in force do not cover many issues that were identified within this project as having an important impact on vehicle riding safety and comfort. This work included the formulation and implementation of a three-level EVOS examination and assessment concept. This article presents results of comparative testing and assessment of the EVOS level for four electric vehicles, i.e. Mega E-City, Citroen C-Zero (Mitsubishi i-MiEV car manufactured by Citroen under a licence), Renault Fluence, and Opel Ampera. The presented results of testing the sample electric vehicles show how much the vehicles differ from each other and how much work still has to be done for improvement of the safety of their operation. Based on the work results, detailed EVOS assessment criteria may be prepared.
Wzrastające wymagania ochrony środowiska oraz wdrażanie najnowszych technologii powodują, że koncerny samochodowe rozwijają produkcję aut z napędem elektrycznym przyjaznych dla środowiska. Trudne warunki drogowe powodują, że kierowcy i pasażerowie pojazdów są narażeni na liczne zagrożenia, szczególnie ich zdrowia i życia. Spowodowało to konieczność podjęcia w PIMOT ważnego problemu Bezpieczeństwa Użytkowania Samochodów Elektrycznych (BUSE), w którym występują nowe dotychczas nierozpoznane zagadnienia. Dotychczas stosowane badania pojazdów EV na zgodność z Regulaminami lub Dyrektywami nie obejmują szeregu zagadnień, które zostały opracowane w trakcie wykonywania pracy a szczególnie wpływających na bezpieczeństwo i komfort jazdy. W pracy przedstawiono i zrealizowano trzystopniową koncepcję badań i oceny BUSE. W pracy przedstawiono wyniki badań porównawczych i ocenę BUSE czterech samochodów elektrycznych: Mega E-city, Citroen C-zero (licencja Mitsubishi iMiEV), Renault Fluence i Opel Ampera. Wyniki badań przedstawionych pojazdów EV wykazują jak bardzo te pojazdy różnią się między sobą i jak dużo jeszcze jest do zrobienia dla poprawy ich bezpieczeństwa użytkowania. Na podstawie wyników pracy mogą być opracowane szczegółowe kryteria BUSE.

Opis:: W artykule przytoczono wyniki statystycznych badań wypadków kolejowych, polegających na wykolejeniu i kolizji pojazdów. Omówiono warunki sprzyjające zejściu koła z szyny w uderzonym wagonie. Przeprowadzono analizę kinematyczną zderzenia mimośrodkowego dwóch ciał o stałej masie i wyznaczono parametry charakteryzujące to zderzenie. Opisano eksperymentalne zderzenie wagonu załadowanego piaskiem z pojazdem doświadczalnym; porównano wyniki pomiarów z wynikami obliczeń zderzenia pojazdów o stałej masie. Stwierdzono, że układ eksperymentalny zachował się podczas zderzenia tak, jakby masa piasku zmieniała swoją wartość.
Results of statistical analysis of railway accidents involving derailment and collision of vehicles are presented in the paper. Conditions favouring derailment of the wheel of impacted wagon were discussed. Kinematic analysis of an eccentric collision of two bodies of constant mass was carried out and parameters characterising that collision were determined. Collision test of the wagon loaded with sand and experimental vehicle was described and test results were compared with the results of calculation of the collision of two vehicles of constant mass. It was found that during the experiment the sand behaved as if its mass was varying. The paper contains the suggestion to supplement experiments concerning behaviour of sand with theoretical analysis of movement of a vehicle of variable mass as well as to work out a method of assessment of risk of derailment during collision of wagon loaded with granular material.

Opis:: The analysis carried out by the authors indicates high threat to the rear seat passengers in passenger cars during a road accident. Vehicle designers indicate potential threats for passengers when they take a position in a car which is unexpected by a manufacturer of passive protection systems. Based on that, the tests were prepared in order to consider several different positions of a rear seat passenger. In particular, attention was paid to a threat to passengers when they take a position unexpected by a manufacturer of the passive protection systems in a car. Indicating and justifying a need to adjust the operation of the individual protection means to a passenger anatomy and current passenger position in a car in order to optimize his protection makes an important aim of these tests. This paper presents the results of the tests performed with a Hybrid III dummy, size M50, placed in three different positions in the back seat of a car. During each test, a series of physical values were measured and the motion of a dummy against the car body and the car interior components were filmed. The effects resulting from a change of a passenger’s position, observed on the courses of dynamic loads occurring during an accident, were analysed. Despite of small changes to a passenger’s position, their significant influence on the dummy movement during a frontal collision of a car and an obstacle was observed.

Opis:: The dynamic loads acting on a human body during a road accident may cause bodily injuries. They are dependent not only on the car structure and applied means of individual protection but also on the anthropometric features of a human body and its location in car. The safety of the car occupants on the rear seats in the passenger cars has been treated as a secondary issue so far. The achieved stage of the structure of that equipment for the rear seat occupants makes an important confirmation of that state. Usually there is no adjustment of the seat belt fixing point position, seat belt pretensioners, seat adjustment. This paper considers the risk of injury for the front and rear seat passengers of the passenger cars on the basis of analysis of dynamic loads that can affect them during the road accident. The attention was paid to the adults and children aged about 10 years. The dynamic loads were analysed with making use of experimental results of frontal flat barrier impact. During the tests, the passengers are protected by typical passive safety systems on the front and the rear seats. In the evaluation used the criteria of the biomechanical human body resistance to the impact load effect. The attention is paid to relations between a seat occupied in a car and the probability of injuries. The analysis of the laboratory impact tests was preceded by the assessment of risk of injury of the front and rear seat passengers in the real road accidents, which has been prepared based on the literature data.

Opis:: The area of the roadway covered with petroleum-derived substance is characterized by lowering the grip of tyres of the vehicle to the roadway. In realistic conditions of the road traffic that kind of obstacles are with difficulty noticeable for the driver and sedatenesses constitute the element of surprise which in combination with violent lowering the rate of the adhesion usually results in loss directional of vehicle. The vehicle which fell into the unchecked skid, in particular on the curve of the road is posing a threat to drivers driving up from the opposite direction on account of random migration of such a vehicle to their traffic lane. Driving vehicles on the roadway this way polluted also have limited possibilities of taking defensive action in order to avoid confronting. For the evaluation of the bearing of drivers in understanding violating by them safety rules in the road traffic on the roadway polluted with vehicles with substances mentioned above applying the rate of the adhesion which is appropriate in calculations and simulations is significant to the analysed road situation. In the article so a problem of the selection of this rate was taken relating to the case study of an existing road accident consisting in inducing collision of two vehicles moving along an asphalt wet roadway polluted with petroleum-derived substance - with diesel.

Opis:: In the article, a brief overview of the measures taken in order to improve the safety of the crews and vehicles is presented. A few examples have been shown. The analysis of the attacks impact on the vehicles was performed on the basis of Polish Military Contingents in Iraq and Afghanistan, In addition, the determinants of endangering of the crews are presented and the resolutions that were undertaken are discussed. It should be noted, that in today's armed conflicts, the safety of the soldiers pursuing combat jobs is a priority. Therefore, the most important issue is to meet the requirements for vehicles security levels. An appropriate vehicle protection level should be taken into account during the determination of the technical assumptions and in the next step verified while the prototype testing in research and development centres. It is assessed that the use of various systems and means of vehicle protection in the new 20 the century have been inspired by operations carried out in Iraq and Afghanistan, where the classics faced the new unpredictable form of combat. However, is unconventional, asymmetric war something new? This is a typical guerrilla war run by the other side by means available for them. It seems that the coalition was not prepared for that form of operations in many regards.

Opis:: W niniejszym artykule poruszono kwestię braku uregulowań prawnych zawierających zasady, których stosowanie zapewniałoby zachowanie bezpieczeństwa podczas przekraczania linii kolejowych przy przewozie ładunków ponadgabarytowych, wymagających wykorzystywania pojazdów nienormatywnych. Sformułowano ogólne zasady zapewniające bezpieczeństwo w takich przypadkach. Wskazano potrzebę pilnego usunięcia błędnych zapisów w obowiązujących przepisach. Problem zilustrowano opisem wypadku, do którego doszło na przejeździe kolejowym przy przewozie ładunku ponadgabarytowego.
Lack of legal regulations dealing with provisions whose application will ensure safety while crossing railway lines during transportation of oversized load requiring the use of non-standardized vehicles is described in the article. General rules ensuring safety in such a case are formulated. The urgent need to eliminate incorrect rules in binding law is highlighted. The description of an accident which occurred on a level crossing during transportation of oversized load is illustrating the issue.
