Opis:
Analysis of possible hybrid drive for tracked vehicle solutions and also concept vehicle project is presented in the paper. Study ofpresent tracked vehicle state-of-art shows that in case majority of currently designed and developed military tracked vehicles projects modifications hybrid propulsion is taken into account. Based on that, authors have decided to develop concept hybrid tracked vehicle study. Basic parameters of concept vehicle are described at the beginning: total vehicle mass up to 14 Mg, maximum speed over 60 km/h and also possibility of stealth operation at the low speed using electric energy stored in batteries. Then, analysis of hybrid electric drives configurations is presented. Three versions of hybrid electric propulsions are considered: two series hybrid drives and one parallel. Then final version is chosen for further development with discussion on justification of the choice description. dynamic model assumptions and modelling methods are described in next section. As a result of simulation, acceleration diagrams for chosen operation modes are shown. As the final stage of concept study, virtual 3D model was built. Virtual modelling methods are used to optimize transmission components layout in a concept tracked vehicle hull.

Opis:
Among grandnesses characterizing fighting vehicles is the so called mobility whose propriety have the essential influence on the dynamic of the vehicle in the field and the active protection against paralyzing chemicals. One of factors having the influence on the motility is the kind and the type of the driving system. Nowadays, the overwhelming majority of tracked fighting vehicles (tanks and infantry fighting vehicles)are equipped with drive unit of the hydro-mechanical type. This type of systems significantly increase motion and mobility proprieties of the vehicle. In the basic tank is implemented a drive unit of the mechanical type. One made an attempt modernizations and the replacement of him with the hydro-mechanical system. As supplementary was accepted hydro-mechanical drive unit whose the construction is modeled on the system HSWL for the heavy vehicle. One skipped the range of adaptive works of the system inside the vehicle. The main attention was concentrated on the influence of the modernization on his traction proprieties. One worked out the original numeric program to determine the traction characteristic of tracked fighting vehicles and special vehicles named DYNH. Data for the analysis one prepared and one worked out using the accessible technical documentation and the expert knowledge of the investigative team. On the work one included some results of numerical calculations of traction proprieties of the tracked fighting vehicle equipped with hydro mechanical drive unit of the type arranged in rows, first class. Results were presented in the form of charts of dynamic and turn characteristics.

Opis:
Contemporary and future battlefield may be characterized by a great dynamism of action in both defensive and offensive operations. It is possible, that armoured and mechanized troops, acting at first attack, will suffer from shortages of supplies of materials and other equipment, especially propellants. It concerns particularly a fuel to engines of driving vehicles. Therefore in many cases for engine powering (as multi-propellant engines or adapted to work on substitute fuels) may be used substitute fuel. The fuel parameters sometimes may be much different from parameters of diesel. So it is substantially important to estimate their dynamics during the planning stage of combat missions. Paper includes attempt to estimate dynamic features of the combat vehicles using substitute propellants. Applying substitute propellants leads to reducing the power of the engine up to 10 % comparing to diesel. It has essential impact on lowering the dynamic ratio at similar level. That leads to lower maximum drive speed at given resistance ofmotion and reducing the ability to climb slopes. There also appears deterioration of spurt, extending the time of reaching speeds at about 17%. Paper shows results of traction calculations of combat vehicles and the influence of powering them with renewable fuel on their effectiveness.

Opis:
Models of electrical energy storage devices – a battery and a supercapacitor – as well as models of motor and a control system, were used to feature the work of a hybrid electric drive system. The models were adapted to simulate driving with a given driving cycle, in a quasi-static method, with the use of MATLAB-Simulink software. The advantage of this method is that calculations can be done quickly and results can be easily compared. A battery model enables determining voltage and charge level in relation to load current and temperature. The basic parameter of a battery is a nominal capacity. It is a measure of energy stored in the battery, which can be absorbed within discharge time, in conditions of temperature and current. The energy can be absorbed until the minimal voltage is reached in the clips. The article presents simulation of calculations lead that the described electric drive model. The model makes it possible to analyse different concepts of steering the whole system already in the initial phase. In particular, the article presents PMSM model and trajectories of selected parameters during a trapezoidal driving cycle.

Opis:
Dynamic combustion engine test stand allows a very accurate analysis of the engine work. The prototype of such a system was developed and built in a cooperation of Poznan University of Technology with the ODIUT Automex company. The system consists of an asynchronous motor controlled by a regenerative variable-frequency drive with an ability to return braking energy back to the power system. Together they permit to set very precise work points of the combustion engine in every time moment, unlike test stands with eddy current dynamometer, which are only able to brake the engine. Measuring system is used to gather data from all sensors, especially torque sensor, which records the torque on a drive shaft. Sensors are connected to electronic boards, which provide signal processing, and data acquisition. Fuel mass flow meter with temperature and pressure control allows regulating the parameters of fuel supplied to the engine. A set of applications is used for test stand management and data presentation and visualization. Real conditions and vehicle dynamics are emulated using advanced models to allow a comprehensive research of the combustion engine on the test stand. The paper covers the description of developed system, its components, software and models adapted in emulation. Moreover, it provides schematics of the system as well as a block diagram of the vehicle dynamic model.
