Opis:: The paper presents testing results that serve the development of research methodology for steerability and stability of military special-purpose vehicles using the SR 60th control robot. Due to their high centre of mass and a large moment of inertia of their body, armoured vehicles pose a serious hazard during dynamic maneuvers. The phenomenon of oversteering is dangerous, which causes automatic reduction in turning radius and thus increases the lateral acceleration at the high-lying centre of mass usually leads to the vehicle rollover. In conditions of a limited tractive adhesion, any slight side impulse (side wind, a drive through a road rut) is enough to result in the vehicle sideslip. At high inertia, each response of any surprised driver is delayed. Therefore, the research studies on behaviour of special-purpose vehicles, including the military ones during road tests are particularly dangerous. The developed methodology allows mitigating the risk of using the steering robot and enables to obtain a very high research results repeatability, unattainable even for a very skilled test driver. The procedure developed hereto is used to accurately determine the safe driving velocity while making sudden maneuvers, and for vehicles steerability characteristics. It may become an excellent tool to verify simulation models.

Opis:: The article presents the results of comparative tests of the experimental designs of the braking system of high mobility vehicles. Braking systems determine the safety of vehicles. Higher mobility requirements should not remain without an effect on adapting the braking system to the use conditions. Article developed within the scope of execution of the NCBiR project DOBR-BIO4/021/13355/2013. The mileage tests lead to a thorough evaluation of the various systems of the vehicle. In order to carry out the mileage test correctly, the vehicle has to be exposed to the most difficult conditions to which it is adapted to, according to the preliminary assumptions. In the case of military vehicles, the most difficult terrain is the training ground terrain with frequent bumps, uphill’s, downhill’s and water hazards, etc. The vehicle has to be operated at the maximum use of all its components (inter-wheel and inter-axle locks etc.). Only the vehicle that has been properly tested, and meets all the assumptions for a given object can be considered safe.

Opis:: In the era of the rapid development of motorization one of the most important characteristics of transport vehicles is the safety and comfort of their drivers and passengers. In particular, people driving vehicles professionally are exposed to vibrations, which may adversely affect their bodies, causing discomfort, dysfunctions, and even lesions of disease. The vibration level triggered by the system a road – a vehicle depends on the type and profile of the road surface as well as the driving speed. Vibration levels are assessed by means of characteristics and comfort comparative indexes determined by experimental methods. Attempts at assessing the comfort while driving along paved roads may be found in many publications; however, there is a lack of information on testing vehicles moving in off-road conditions, which is substantial from the point of view of military vehicle crews’ comfort. The driving comfort of crews of wheeled vehicles is subjected to examinations at the Military Institute of Armored and Automotive Technology.

Opis:: The paper presents a concept of autonomic logistics system of intelligent military motor vehicles. A classification of vehicles and a definition of intelligent motor vehicles has been provided. The intelligent motor vehicle distinguishes the functional components systems and the integrated control system. The integrated system has been defined to control the intelligent motor vehicles, including subsystems of: data identification, information-and-decision-making and executive components. The data identification subsystem distinguishes the following components: logistic about the state of environment, navigation, and communications. The automatic logistic system consists of the following subsystems: diagnostic, operational, security, and power supply. The purpose and tasks of those subsystems have been examined. The information and decision-making subsystem has been defined: classic, expertise, and hybrid. Tasks of the vehicle setting components subsystem have been defined. A place of autonomic logistic system in the structure of the military motor vehicle has been determined. The development of a design and the implementation of the proposed concept of the autonomic logistic system will significantly increase the performance properties of military motor vehicles in aspect of effective execution of their combat missions.

Opis:: The paper presents a new method for diagnosing internal combustion engines with automatic ignition in traction conditions. Its substance involves determination of engine torque on the basis of recording of acceleration in road conditions. Extensive preliminary and primary experimental research has been conducted. Three variants of the internal combustion engine diagnostic model have been developed using a trivalent evaluation of states. Algorithms have been proposed to control a state and location of engine defects. The new method has been verified in traction conditions. A probability of a correct diagnosis of internal combustion engine is 0.85 ÷ 1.
W pracy przedstawiono nową metodę diagnozowania silnika spalinowego o ZS w warunkach trakcyjnych. Istota polega na wyznaczeniu momentu obrotowego silnika na podstawie rejestracji przyspieszenia w warunkach drogowych. Wykonano obszerne wstępne i zasadnicze badania eksperymentalne. Opracowano trzy warianty modelu diagnostycznego silnika spalinowego, z wykorzystaniem trójwartościowej oceny stanów. Zaproponowano algorytmy kontroli stanu i lokalizacji uszkodzeń silnika. Zweryfikowano nową metodę w warunkach trakcyjnych. Prawdopodobieństwo poprawnej diagnozy silnika spalinowego wynosi 0,85 ÷ 1.

Opis:: The paper presents an outline of a new strategy to improve operational system of military motor vehicles. Technical diagnostics method is a tool for controlling the motor vehicles maintenance in the state of their functional and professional operability. Three criteria have been assumed to control and maintain vehicles in the state of their technical operability, effectiveness and safety. It was found that the safety of military vehicles is controllable by board-external diagnostic systems as well as diagnostic systems as part of their operating systems. An algorithm is presented for diagnosing, maintaining, and assessing vehicles security in combat. It was found necessary to develop an improved technology for vehicles maintenance, including technological processes, organization of the processes implementation progress and their infrastructure. The organizational chart has been presented of the motor vehicles technological diagnostics and maintenance process. The paper also includes the concept for assessment of the vehicles operational effectiveness based on criteria of the static and dynamic coefficient of technical readiness and costs.
