Opis:: W pracy przedstawiono rezultaty obliczeń modelu czołgu poddanego oddziaływaniu obciążeń o charakterze udarowym generowanych podczas strzelania z uzbrojenia podstawowego oraz po trafieniu kadłuba lub wieży pociskiem przeciwpancernym. Podwyższenie skuteczności pocisków może być realizowane między innymi następującymi drogami, poprzez zwiększenie prędkości początkowej lub poprzez zwiększenie jego kalibru. Jedno i drugie powoduje wzrost obciążenia konstrukcji czołgu. Dane o rozkładzie prawdopodobieństwa trafienia czołgów z okresu II Wojny Światowej oraz informacje z minionych konfliktów zbrojnych wskazują, że współcześnie najbardziej zagrożona jest wieża czołgu, w której rozmieszczone jest uzbrojenie podstawowe i system kierowania ogniem. Jednakże niezależnie od miejsca trafienia czołgu obciążenie przenosi się na załogę i wyposażenie wewnętrzne, również w przypadku uderzenia pocisku niepowodującego przebicia. W pracy pokazano rezultaty analizy numerycznej stanu wytężenia wybranych elementów kadłuba dla przyjętych wariantów obciążenia oraz przebiegi czasowe przyspieszeń działających na elementy konstrukcji i członków załogi.
In paper there were presented results of calculations of tank model exposed to impact of loads generated while gunshot and after hull or turret hit by armour-piercing shell. Increase of the fire efficiency may be achieved, among others, by increase of shell initial velocity or by increase of its caliber. Both methods cause increase of construction loads. Statistical data about probability distribution of direct hit of Second World War tanks and information about recent military conflicts show, that today the most threatened tank part is the turret, with arranged armament and fire control system. However regardless of the hit-point, load spreads on the crew and inner equipment, as well in case of shell hit on the rebound. In paper there were shown the results of numerical analysis of the strain state of selected hull elements for assumed load variants as well as time courses of accelerations acting on construction elements and crew members.

Opis:: This paper presents issues related to the process of designing a 30-feet container to be used as a mobile laboratory for collecting the environmental samples and identification of biological threats. Tactical and technical assumptions for the container, taking into account the requirements of the transport and movement of the army at long distances and in the difficult areas by means of transport characterized by increased traction properties, made the starting point. A possible way of relocation on the land roads using commonly available and military means of transport, possibilities of loading and unloading using the autonomic system and automatic levelling system are described. It describes the process of creating the MES model of the supporting structure and assumptions taken for that purpose. The basic assumption included invariability of shape, geometry and dimensions of a container compared to containers recognized in the world as the standard ones. Some results of numerical calculations carried out at two stages are presented. At the first stage, the issues on the own values were solved. Frequencies of own vibrations and associated forms of vibrations were identified. At the second stage, forced container vibrations were analysed. Resistance calculations were performed for the supporting structure of the container in the aspect of evaluation of the strain condition of the whole structure, as well as its components for assumed load variants. A variability of resistance calculations takes into account such cases as the influence of the under-container trailer riding on the uneven ground, loading and unloading a container from a trailer using autonomous system, diversity of loads on the supports resulting from the change of the ground density under the supports. A preliminary analysis of container transport possibilities and transport unit traction properties have been also carried out.

Opis:: The work analyzes the possibility of using a truck chassis in terms of installing a specific device. As part ofwork was selected the vehicle, identified the necessary geometric parameters and the mass allowing of modernization, with particular emphasis on the required structural changes in the front and rear suspension. To this were used, the developed two phase methodology of calculation of the metal elastic elements (springs) and mechanical lateral tilt stabilizers. Results of numerical calculations are presented in the form of recommendations to redesign of the front and rear suspension. However, in the front suspension should be made a new spring and a mechanical lateral tilt stabilizer, while rear spring suspension meets the requirements in terms of elastic characteristics (adequate the coefficient of rigidity) is requiredonly adjustment of the static deflection of the suspension for example by adjusting the radii of leaf of the spring. Because of the design solution of the driving rear axle (so called driving axle trolley) was not proposed mechanical lateral tilt stabilizer. Paper present diagram of the forces acting on a vehicle with special equipment, results of the calculation loads acting on the suspension components fitted to a lorry with a special device, results of the calculation loads acting on the base vehicle suspension components, the basic parameters of a lorry with special hull and performance graph of the front suspension leaf spring resilience.

Opis:: The work presents selected results of experimental research on special purpose vehicles used on military training grounds, and bench tests of their main structural elements. The results are connected mainly with identifying the main vibration parameters of those vehicles (regarding weight, resilience and damping), and with the assessment of the level of dynamic loads. The more output data experimental research provides, the more input data we have for designing models. Determined in laboratory tests, weight parameters (regarding weight and moments of inertia), coefficients of stiffness and damping, as well as selected resilience and damping characteristics, are applied in the process of creating the numerical models of assemblies, systems, and complete vehicles. The numerical models created are subject to full verification in order to minimize the differences between the real objects and their representations. The models are applied in multivariate simulation tests of the existing design solutions, upgrading them, or creating new designs. Due to a certain sensitivity of the range of special purpose vehicles, the results of experimental tests and simulation analyses presented in the work are mainly qualitative rather than quantitative.

Opis:: Participation of Polish military contingent in peach and stabilization missions resulted in the need for new vehicles. Special vehicles - multiaxle ones of good protection abilities and high motion dynamics - have to be adjusted to operation in various climate and terrain conditions. The work presents operation conditions of the wheeled armoured carriers resulting from the execution of required tasks. Threats resulting from driving on unpaved roads and wilderness have been presented as well as their influence on the motion dynamics, technical condition of vehicle chassis, durability and reliability. It is particularly important for the passenger safety. A mathematical vehicle model, imitating special multiaxle vehicle, have been presented. Calculation abilities of original numerical software for the analysis of vehicle traction characteristics have been presented. Mechanical and hydromechanical drive vehicles can be analysed. Examples of calculation results, illustrated on the diagrams, have been also included. Influence of selected technical - structural parameters on a multiaxle vehicle has been shown. Their influence on traction characteristics and dynamic loads affecting the vehicle, its internat equipment and the passengers has been estimated.

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:: Military vehicles are used less intensively than the civil ones, and many types of the vehicles used by the army are stored for a long time. Therefore, this type of vehicles can be used even for a dozens of years. Due to the constant development of technology, used armament and military equipment has to be adjusted to current needs. The above applies also to recovery vehicles, including field workshops. This work analyses the level of safety and comfort of the crew of the modified field workshop (Sarna II) when the vehicle is moving under various conditions. The scope of improvement included two seats inside workshop for the transportation of the crew members. Experimental research involved measuring the accelerations on the seats of the crew and the noise inside the vehicle body. The assessment was conducted on the basis of the highest value of 8-hour of the exposure to the whole body vibrations A(8). The accelerations acting on the seats were determined mainly by the kind of the road, its roughness and the speed of the vehicle. The occupational risk connected with the exposure to the mechanical vibrations was in most cases assessed to be low or moderate. The risk was assessed to be high only when the vehicle was moving on the dirt road. Results of experimental researches indicated that passengers travelling in the body of Sarna II workshop, mounted on the underbody of STAR 266M2 vehicle, have ensured proper conditions of transport, both in terms of exposure to mechanical vibrations and to the noise.

Opis:: The extortions that result in the vibrations of a hull of the combat vehicle have an impact on the tracked combat vehicle during the off-road driving. They may have a negative impact on the crew, internal equipment, shooting accuracy. A level of the hull loads depends on quality of the suspension system, which main responsibility consists in minimising an amplitude of the vibrations. Therefore, it is necessary both to improve a structure of the suspension system, and its components, as well as their optimisation. The tests of the driving smoothness of the vehicle and quality of the suspension elements can be realised both within a frame of the model tests and while driving in the real conditions. The assessment criteria of the driving smoothness are directly related to the negative influence of the vibrations to the human body. The suspension quality should be assumed both upon an execution of the vehicle prototype, and during the design or modernisation phase. It results both in reducing the time, and minimisation of the costs and risk related to the structure development. The model tests enable to evaluate the driving smoothness and comfort prior to an execution of the prototype. The tests on the test tracks in the final phase of the development are carried out in order to evaluate the driving smoothness.

Opis:: Since the beginning of the 90’s, a scientific team in the Motor Vehicle and Transport Institute of the Mechanical Department in the Military University of Technology, has been involved in the model and experimental tests of the existing structures of the military vehicles (tanks, combat infantry vehicles and wheeled armoured carriers) in the aspect of their modernization. A part of works is related to the military vehicles included in the army’s equipment and the other parts are related to newly designed vehicles. In both cases issues related to the behaviour of selected assemblies and the whole vehicle, structure during threats posed by the reality of contemporary battlefield or armed symmetric or asymmetric conflicts are analysed. Selected effects of the tests and analyses will be presented mostly within the qualitative scope due to the data sensitivity. Contemporary design of military vehicles requires involvement of various research methods and specialized calculation software. The results obtained during performed various experimental tests make a valuable basis for verification of numerical models used in design process and multi-option simulation calculations.

Opis:: The results of the experimental research on the influence of the special vehicle movement conditions on the body shell and the vehicle crew dynamic load will be presented in the paper. ROSOMAK Wheeled Armoured Personnel Carrier (Wheeled APC), the basic version, was the subject of the research. The research work was aimed at analysis of the dynamic loads resulting from the deterministic inputs and driving on the selected types of surfaces generating random kinematic inputs. The personnel carrier service conditions, measuring apparatus, and testing methods will be described. The vertical accelerations of the selected points of the vehicle, and deflection of the prime and second suspension of the vehicle left side were measured. The time and the acceleration RMS value spectrum charts for the selected implementations will be presented. The cumulative statistics will be shown in the form of a table. The conclusions regarding the influence of the road surface on the personnel carrier driver's working comfort will be formulated. The assessment of the suspension quality will be included in the conclusions. Driving on the smooth surface is comfortable. However, the road surface worsening causes decreased proficiency sense until the exposure limit boundary is reached when the vehicle drives on a poor quality cobble road with 50 km/h speed. The vehicle basic version is not fitted with the seats for assault troops, therefore the influence of the road irregularities on the centre of mass of the body shell, and the driver's and commander's seats were determined. It is recommended to make further tests on the personnel carrier combat and special versions.
