Opis:: For a few years, the sales of motor vehicles with hybrid drive systems (referred to as “hybrid vehicles” or “HVs”) have been rapidly growing. However, there is a lack of information about the intensity of operation of vehicles classified in this category, which is completely new. A calculation procedure has been presented that enabled evaluation of the HV mileage growth rate. An analysis of this rate provides grounds for forecasting the changes that are likely to take place in the fleet of motor vehicles, such as the progress in the process of replacement of conventional vehicles with vehicles with alternative drive systems, and this may be a basis for predicting the reduction in fuel consumption and exhaust emissions. Models of the HV mileage growth process have been defined for three different countries. They indicate high mileage growth rates in the initial period of vehicle operation, e.g. until the fourth year of operation of the Auris H cars. The highest mileage growth rates in this period were observed in the Netherlands and Poland. In Germany, this rate was lower by 41%. Significant differences in the intensity of vehicle operation have been observed between the behaviour of HV owners in the countries under analysis. A considerable drop in the annual HV mileage as early as in the fifth and sixth year of vehicle operation is an alarming signal.

Opis:: The motor vehicle operation process results in a growth in the vehicle mileage and the rate of this growth is usually characterized by specifying the value of this mileage (in km) calculated per a time unit (month, year, etc.). In this paper, the relation between the specific mileage (km per a time unit) of a motor truck and the engine capacity category has been analysed. Results of calculations based on the observation of the mileage of over 3 600 motor trucks of more than 3 500 kg gross vehicle mass (GVM) have been presented. In the analysis, intervals of equal width were adopted in which the mileage values (in km) were grouped. The percentage of the vehicles whose monthly mileage values belonged to the ith interval was calculated. The resulting set of k discrete values of the percentage of the vehicles with predefined mileage was approximated by a polynomial. The approximation functions are polynomials of the fifth or sixth degree. The curves representing such functions very well describe the distribution of values of the mileage of motor vehicles with engines of over 10000 cm3 capacity. A characteristic feature of the calculated distributions of vehicle mileage values is the fact that the location of the areas of predominating mileage values strongly depend on the engine capacity. The highest values of the monthly mileage of motor trucks with engines of up to 5 000 cm3 capacity do not exceed 9 500 km and increase to 12 500 km for trucks with engines whose capacity exceeds 12 000 cm3. Based on the profiles of the approximation functions, it has been found that the mileage values corresponding to the first mode of these functions decline with increasing engine capacity values. Simultaneously, a decrease can be observed in the percentage of the vehicles with short mileage with a growth in the engine capacity values. Conversely, the motor truck mileage values corresponding to the second mode of the approximation functions markedly increase with growing engine capacity values. An increase can also be seen in the percentage of the trucks with long mileage in the group of vehicles with engines of over 10000 cm3 capacity.

Opis:: In the article the authors have attempted to analyze the specifications and criteria imposed on military vehicles acquired by the Polish Armed Forces. The issues of selection of the target operation standard, interval between periodic maintenance inspections, fault tolerance and reliability, which are defined in tactical-technical criteria by administrators, were addressed. The technical specifications are the essential component of qualification studies. The data obtained from research of prototypes and the initial years of exploitation of the new military equipment (SpW) constitute the source of verification for technical-tactical criteria (ZTT) or initial technical-tactical criteria (WZTT) adopted for implementation. The article also discusses the issues related to estimation of probability of the tasks to be executed by military vehicles in typical operating conditions depending on the lifetime, mileage or method of storage. Presumable combat losses, which are independent from the adopted operation system of the military equipment, have been omitted. The research works in the field of reliability are conducted in the Armored Fighting Vehicles Laboratory of the Military Institute of Armored and Automotive Technology in Sulejówek. Additionally, the authors have addressed the possibility of the application of computer simulation for the purpose of military vehicles reliability.

Opis:: The study discusses the issue of determining the conditions for testing the mileage of a vehicle. Lifetime tests are the crucial element of qualification tests. This type of research verifies the resistance of vehicles and elements of their on-board equipment to vibrations and shocks resulting from the interaction of uneven surface during the movement. Certain test conditions can be straightforwardly determined and verified e.g. weather conditions or a type of the road/surface. The problem appears when the tests are to be conducted in field conditions (off-road). At the set driving speed, the level and frequency structure of dynamic loads of elements of a vehicle drive system depend mainly on a surface profile and its viscoelastic conditions. Either the profile or the characteristics of ground foundations change over the time depending on various factors. The paper attempts to assess the interaction of a ground surface of selected field roads on a vehicle. The result of direct measurement of the vertical acceleration captured on a drive axle and on a vehicle’s frame above the axle was addressed. The measurement results were analyzed within the context of possible planning of vehicle test requirements with the application of the method of testing mileage under the field conditions.

Opis:: The intensity of use of motor vehicles and the range of the transport jobs performed change during the many-year operation of such vehicles. The changes are introduced in result of ongoing analyses of actual current vehicle operation costs, reliability, and performance characteristics. The changes in the vehicle operation process, taking place with vehicle’s age, were analysed on the grounds of the mileage of over 9 000 motor trucks. The analysis covered a 20-year period of vehicle operation. The analysis results were used to estimate the mathematical models that describe the basic characteristics of the mileage growth process, with changes in these characteristics as observed in the recent years along with an intensive development of the road transport in Poland. Models of vehicle mileage growth have been developed for seven categories of engine cubic capacity. The coefficients of model equations have been given and the accuracy of the mileage values calculated on these grounds has been comprehensively evaluated. The relative measures of the scatter in the mileage values obtained from these models do not exceed 12 % of the average values determined from experimental data. A procedure has been proposed that leads to evaluating the mileage growth process and is based on the experience having already been gained in this field. It has been shown that the mileage growth process is strongly related to the engine cubic capacity. The mileage growth process is an important source of information for the planning of vehicle operation, forecasting of costs, and estimating of exhaust emissions and energy consumption in the whole cycle of operation of motor vehicles by transport companies.
W czasie wieloletniej eksploatacji samochodów zmianie ulega intensywność ich użytkowania oraz zakres realizowanych zadań transportowych. Zmiany te są rezultatem analizy kosztów eksploatacji, niezawodności oraz osiąganych parametrów trakcyjnych. Zmiany w procesie eksploatacji, które zachodzą wraz z wiekiem samochodów, analizowano na podstawie przebiegu prawie 9000 samochodów ciężarowych. Analizowany jest dwudziestoletni okres eksploatacji pojazdów. Rezultaty tej analizy wykorzystano podczas estymacji modeli matematycznych, które opisują zasadnicze cechy procesu narastania wartości przebiegu, pojawiające się w ostatnich latach wraz z intensywnym wzrostem transportu drogowego w Polsce. Opracowano modele narastania przebiegu w siedmiu kategoriach pojemności silnika. Podano współczynniki równań tych modeli oraz dokonano wszechstronnej oceny dokładności obliczonych na ich podstawie wartości przebiegu. Obliczone względne miary rozrzutu wartości przebiegu z tych modeli nie przekraczają 12% od wartości średnich, wyznaczonych z danych eksperymentalnych. Zaproponowano procedurę postępowania, która prowadzi do wyznaczenia oceny procesu narastania przebiegu i jest oparta na dotychczasowych doświadczeniach w tym zakresie. Pokazano, że proces narastania przebiegu ma silny związek z pojemnością silnika. Proces narastania przebiegu jest ważnym źródłem informacji podczas planowania eksploatacji pojazdów, prognozowania kosztów, a także oceny emisji spalin i zużycia energii w całym cyklu eksploatacji samochodów w firmach transportowych.

Opis:: The article presents expert estimates for 2010 and a forecast up to year 2030 regarding the number of passenger cars as well as trucks and special vehicles and buses according to the maximum weight group. In case of trucks and special vehicles, included were vehicles with maximum weight of less than 3.5 Mg and maximum weight of more than 3.5 Mg. As regards buses – the condition and forecast number of buses with maximum weight of less than 5.0 Mg and more than 5.0 Mg was presented. The forecast concerning passenger cars and other types of vehicles with maximum weight of less than 3.5 Mg (5.0 Mg in case of buses) focused on the number of vehicles by type of energy. The following types of energy were included: petrol, diesel oil, LPG, NG and electrical energy in case of passenger cars and light duty trucks. Estimates also included the average annual statistical mileage of a vehicle registered in Poland according to the specified category and type of energy. Based on the assumed assumptions in the 2030 perspective – the average fuel consumption was determined per 100 km of statistical mileage in every specified category. The predicted consumption of respective types of energy by the overall Polish car fleet was calculated and according to the specified category in years 2015, 2020, 2025 and 2030.

Opis:: Extensive environmental protection activities include the promotion of alternative drive systems for motor vehicles. An important role in this field is played by hybrid vehicles, with their low operation costs being a strong marketing argument. Can such economies be conducive to the intensity of use of hybrid vehicles compared with vehicles with conventional drive systems? To answer this question, the intensity of use of hybrid vehicles was observed in a few different countries. The attention was focused on the occurrence of extreme (very low and very high) mileage values within comparable vehicle groups. The survey carried out has revealed distinct differences in the intensity of use of hybrid vehicles compared with motor vehicles with conventional drive systems (IC). The average mileage values for hybrid vehicles are higher than those recorded for conventional ones during the same period, but this difference can only be seen in the initial period of vehicle use, rapidly decreasing with vehicle operation years. The share of vehicles with extreme mileage values recorded during the period under observation, presented in the paper in several ways, declines with the years of vehicle use. In spite of that, however, the percentage of vehicles with extreme mileage values is high in HVs group against IC.
