Abstract:

In recent years, the interest of the scientific community in perforated plates for ballistic protection has increased. Perforated plates do not represent protection by themselves, rather, they are used in the armour systems of armoured vehicles, in conjunction with base armour, since they are intended to induce bend stresses, where a penetrating core fracture occurs. The fragments are subsequently stopped by base armoured vehicle armour. Although for the first time used several decades ago, perforated plates are found to be attractive even today. The main reason is the combination of very convenient properties. Besides high mass effectiveness, they possess a high multi-impact resistance, since their perforations arrest cracks. Therefore, a relatively wide array of materials is suitable for perforated plate fabrication, ranging from alloy steel to some types of cast iron. Being made of metallic materials, raw material costs are relatively low compared to ceramics or composite materials, making them very attractive for present and future armoured vehicles. Finally, armour system consisting of a perforated plate and base plate at some distance, reduce the effectiveness of both shaped charge jets and act as blast mitigators.

Abstract:

Since the Second World War, the major armed conflicts have been occurred in or in the vicinity of the urban areas rather than rural areas, amongst conventional armies and armed groups or terrorists/insurgents. The architectural and construction characteristics of the urban area increase the opportunities for armed groups to ambush, easily escape, conceal, relocate and attack. Additionally, the narrow streets, the blocked roads by the debris of buildings, and IED threats make the urban areas one of the most dangerous conditions for infantries and armoured vehicles. The majority of present armoured combat vehicle types due to the limited visibility, low manoeuvre capability, and limited firing power, they are insufficient for performing the standalone operation without infantry forces and combat engineer support in urban warfare conditions. In this study, 13.400 data belonging to 676 attacks towards armoured vehicles during the counter-terrorism operations against PKK/PYD and ISIS in the urban areas were analysed within the perspective of forensic science techniques such as forensic ballistics and shooting reconstruction. According to the examinations and analyses carried out within the scope of this study; the leading critical features that an armoured combat vehicle that will operate in the urban areas may be listed under five general headings: Structure, Ballistic Protection and Armour, Self Defence and Weapon Systems, Situational/peripheral Awareness and C4I2 Systems and Integrated Warfare Systems.

Abstract:

<p align="JUSTIFY">The ultimate goal of armour research is to create better armour for battle worthy combat plat forms such as main battle tanks, infantry combat vehicles and light combat vehicles. In each of these applications, the main aim boils down to one of the two things; either reduce the weight without sacrificing protection or enhance the performance at same or even reduced weight. In practice, these ambitions can be fulfilled only if we have with us, appropriate improved armour materials, advanced and innovative technologies and also improved designs, which enable us to use them for creating next generation armour modules. Armour systems have progressed through improvements in metallic, ceramic and lightweight (low areal density) composite materials. Similarly, the advances in development of explosive reactive armour (ERA) and non-explosive reactive armour (NERA) have generated efficient armour system against contemporary high explosive antitank ammunition and missile threats for the armoured vehicles. Yet, to achieve armour performance exceeding that of the current light combat vehicles and main battle tanks, further advancements in armour materials, systems, and survivability technologies are required for new vehicular systems that weigh significantly less than the present combat platforms. Various approaches and advancements in the metallic and composite armour materials, ERA and NERA systems to improve the survivability of armoured vehicles in the futuristic multi-spectral battlefield scenarios are described.</p>

Abstract:

Modelling the armour-piercing bullets B-32 calibre 12.7 mm penetration into the double-layer ceramic-composite armour has been performed for the armour blocks of two designs. The first one is a layer of ceramic square tiles supported by the glass or polyamide fabric. Modelling and subsequent ballistic tests have shown that the conical Hertz crack localized in the ceramic tile is formed. The tile is destroyed from the spread of radial cracks, and the entire armour unit becomes unable to sustain the repeated hit of the bullet. In the second case, the armour block consists of the discrete epoxy-filled cylindrical ceramic elements with spherical ends. The advantage of this "discrete" armour is localization of the damage zone and thus an ability to sustain the multiple bullet hits. The ballistic tests of the compared armour units have shown that both provide effective additional protection of light-armoured vehicles against the normal impact of the calibre 12.7 mm bullet.

Abstract:

The experience of military conflicts in recent decades shows changes in the nature of warfare performance, which differ significantly from those conditions for which existing types of armoured fighting vehicles were created. The conducted analysis of the works on the designing of advanced armoured fighting vehicles shows that these changes have not yet been sufficiently taken into account. It still focuses on the creation of high-value combat vehicles with high combat performance for direct (contact) actions. Given the limited economic opportunities of the most countries this inevitably leads to unreasonable expenses. This article presents a conceptual approach to design up to date of armoured fighting vehicles which is based on the asymmetrical principle of their development. Given that the practical implementation of the proposed approach is complex and high-cost, the results of simulation modelling of typical situations of combat use of the offered types of armoured fighting vehicles are given as evidence.

Abstract:

Occupant safety in an armoured vehicle is of paramount importance. Most serious threat to armoured vehicles comes in the form of explosion of buried charge or an improvised explosive device. The use of numerical methods in the validation process of light armoured vehicles reduces the number of prototypes required and decreases the design time. This paper elucidates the process by which one such validation using numerical methods was done. The process of finite element method used for simulation of blast is a prominent method of numerical method of simulation. The finite element model (FEM) process starts with discretisation. By discretisation or meshing, Shell (Quad/Tria) and solid (Tetra/Hexa) elements are generated. The FEM thus created is provided with relevant material model / properties and loading and boundary conditions. The loading conditions are adopted from STANAG 4569 Level II standards. Local deformation, global displacement, stresses and time history of displacement of particular areas of interest are obtained as results. Comparison results include the effect of with and without thermal softening under blast. Based on the results and comparison, suggestions regarding re-engineering the vehicle are presented.

Abstract:

Landmines severely threaten the armoured vehicles. The principal objective is to present a methodology for blast simulations of vehicles subjected to landmine explosions. First, free field blast experiment of 2 kg TNT charge in a steel pot is carried out to validate the blast parameters used in the numerical simulation. Overpressure-time history collected in the free field blast experiment is compared to the numerical simulation results. Numerical simulations are performed in LS-DYNA hydrocode that employs Arbitrary Lagrangian Eulerian formulation enabling a fully coupled interaction between the blast wave, the detonation gases, and the vehicle. Second, the full-scale field test of an armoured vehicle exposed to 6 kg of TNT charge in a steel pot underneath the rear end of the vehicle is conducted. Maximum dynamic deformations measured inside the vehicle are compared to the results calculated in the numerical simulation. Results show that the numerical simulation is in good agreement with the full-scale field test.

AbstractThe research paper reviews selected issues associated with the current state of the armoured (tanks) and infantry fighting vehicle technology, with particular emphasis on the operating effectiveness of elongated sub-calibre projectiles fired from tank guns, which enable full perforation of ca. 500 mm thick armour steel plates. Their efficiency is comparable with the impact of shaped heads with armour steel penetration capabilities, and amounts from 6 to 8 calibres – warhead diameters. Furthermore, the paper discusses a numerical analysis, which shows the velocities of elongated projectiles (of tungsten matrix sinters) required to achieve a determined armour steel penetration depth. In addition, it also presents the performance characteristics of two 100 mm calibre shaped warheads, with copper inserts and apex angles of 51º and 60º.

Abstract:

The present generation Armoured Tracked Vehicles (ATVs) are constructed using Rolled homogenized armour (RHA) grade steels closely confirming with AISI 4340 specifications. However, in future Armoured Tracked Vehicles (ATVs), the overall weight of ATVs has to be reduced enormously and hence, the designers have prescribed to employ Ultra High Hard Armour (UHA) steels for the construction. Welding is considered to be one of the important fabrication methods in ATVs construction. However, welding of UHA steels is highly challenging due to higher hardness and higher carbon content. Shielded Metal Arc Welding (SMAW) is among the most widely employed welding process in the construction of ATVs since it is more versatile and cost-effective. Armour grade steels are welded conventionally using Austenitic Stainless Steel (ASS) consumables to eliminate the serious problems of hydrogen induced cracking. Hence, in this investigation, an attempt has been made to study the influence of ASS welding consumables on tensile properties and hardness of UHA steel joints made by SMAW process. UHA steel plates having 15 mm thickness were welded by SMAW process using five different ASS consumables (having different Creq/Nieq ratio). Tensile properties (unnotched and notched) of the welded joints were evaluated. From this investigation, it was observed that the joint welded using ASS consumable (having higher Creq/Nieq ratio) exhibited superior tensile properties as result of the evolution of ferrite phase with vermicular and globular morphology in the austenite matrix at weld metal region.

Abstract:

Abstract During the last decades, the military combat vehicles and trucks were equipped with various weapon systems and laser rangefinders, optical devices and sighting equipment. The military vehicles were thus upgraded, so they become a more attractive target for enemy fire. Since ballistic armour cannot and will never completely protect vehicles against kinetic or explosive ammunitions, various pyrotechnic countermeasure systems such as smoke screening, were designed and implemented. Generating smoke screens or flares in the desired area (around the combat armoured vehicles) is a concern of many manufacturers of pyrotechnic protection systems, aiming to protect against detection in the visual (VIS) and infrared (IR) spectrum. The goal of this article is to present a brief state-of-the-art regarding the development of pyrotechnic smoke camouflage systems and flares used to ensure countermeasures in the visible and infrared electromagnetic spectrum. Types of pyrotechnic systems and structures for the protection of military vehicles will be described briefly.

Abstract:

Despite the intensive development of plastics and composite materials in the case of armours employed to protect vehicles, armour steel remains a material commonly and effectively used. This is especially evident in the base armour of armoured vehicles, where the body is made of welded armour steel plates. However, the area of joining both the weld and the heat affected zone are sensitive areas with the reduced protective capability. In the case of laser welding in comparison with methods such as shielded metal arc welding and gas metal arc welding, it is possible to narrow down the above mentioned areas. The paper presents the results of research on the protective capability of welded zone of armour steel plates with a hardness of 500 HB. In the first part of the work, in order to select the proper parameters for the bonding process, different connection variants were made and their microstructure and selected mechanical properties were analysed. After selecting the best variant of the welding process, samples (200 mm × 200 mm) consisting of two welded plates with dimensions 100 mm × 200 mm were made for testing. The thickness of the plates was selected in such a way that in the areas outside the bonding zone, the lack of complete perforation by the projectiles used in the tests is guaranteed. The samples were shot at the weld location and at different distances from the weld to verify, for the chosen method of joining steel plates, if the welded armour loses its protective capability and, possibly, how wide this area may be.

Abstract:

The article also tackles topics related to dynamic testing of vehicles equipped with massive wheel inserts. The subject matter was taken due to the modernization of the Polish Armed Forces. The majority of vehicles obtained for the army are equipped with wheels with massive inserts. With the introduction of this solution to the army, there was a need to check the correctness of the operation of wheels with massive inserts. The Military Vehicles Research Laboratory of the Institute of Armoured and Automotive Technology developed a research method, which the authors presented in the following article. Dynamic testing is carried out in a practical way by unsealing the tire. The results of dynamic tests carried out on a selected military special vehicle equipped with wheels with massive inserts, which allow the vehicle to move after the tire is unsealed, were also presented. This condition can be caused by various situations, such as: passing the vehicle through the spike strip or the shooting through the tire. Special vehicles, both military and police, are highly vulnerable to the above events and must be able to evacuate from the place of danger even in the case of an unsealed tire.

Abstract:

Better terrain accessibility of military vehicle makes it possible to project force at desired points in a theatre of operation. The factors responsible for terrain accessibility are slope, obstacles and soil. Torque requirement for meeting vehicle speed and gradient requirement is understood and can be analytically arrived at. It can be met by appropriate choice of engine and transmission using. There is dearth of information as well as a common metric in quantification of terrain accessibility especially soft soil trafficability. Approach adopted in this study is that of characterisation of vehicle in terms of mobility characteristic and mobility limit parameters and comparing them with vehicle in-service worldwide. Simple empirical relation has been preferred over complex analytical approach for mobility prediction and gradient climbing capability in sand has been predicted and compared with other vehicles. parametric study for tyre sizes vis-a-vis mobility parameters have been obtained and results have been presented for chosen vehicle configuration. Second part of this study is obstacle crossing capability study for standard set of obstacles. Vehicle model has been built in multi-body environment and parameters of significance viz., wheel displacement to verify correctness of model and acceleration at CG for ride comfort and ground reactions for evaluation of dynamic loads on axles have been obtained. Vehicle drivetrain configuration to achieve desired terrain accessibility in terms of soft-soil trafficability and obstacle crossing has been demonstrated.

Abstract:

A two-dimensional computer simulation model is developed for dynamic analysis of high-mobility tracked vehicles fitted with a trailing arm suspension system. The simulation model is oriented as a design tool for detailed analysis of vehicle suspension dynamics and ride quality assessment. The Lagrangian model formulation of a tracked vehicle is derived by considering a rigid terrain of an arbitrary profile and constant forward vehicle speed. The model incorporates detailed representations of a vehicle suspension system and dynamic wheel-track-terrain interactions. The wheel forces are evaluated based on an adaptive footprint formulation of a wheel/track-terrain contact patch, and the track forces are modelled based on kinematic considerations. The computer model predictions are validated against field measurements, which were gathered from an extensive field testing of an in-service armoured personnel carrier. The comparison between measured and simulated dynamic responses exhibits a fairly close correlation.

Abstract:

Critical to quality factors of engineering design process of armored vehicles includes establishing the effects that defects have on the quality of mechanical objects as per engineering assessment criteria. Determination of the factors is an original part of work known as the Optimal Design For Six Sigma [9], which defines a defect as an inconsistency between parameters and the technical specification limits of the mechanical object. The basis for determining the common factors of the effects of defects is established through conducting surveys among users and establishing the significance of the engineering assessment criteria. Innovative product design based on the measurable quality factors and crucial for customers allows effective optimization of the object, and the ability to achieve a stable and optimal degree of product quality. In effect, this method enables to limit the occurrence of defects through preventive actions.

Abstract:

Provision of proper protection against landmines is a major aim of modern military vehicle designs. The point of developing the methods and means of countermine protection is to identify the shock wave impact on a vehicle construction and its crew. Information on overload coming from landmine explosions on a person are strictly confidential or not detailed enough. The basis to obtain them is to carry out experimental and numerical tests. This article presents basic issues and threats to crews as a result of landmine, IED or EFP explosions carried out by terrorists. The literature published has helped the authors to identify the main parts of body prone to the impulse load of a shock wave explosion on a wheeled military vehicle. The methodology and sample results of experimental tests identifying the shock wave load on a vehicle and its crew in a characteristic anthropometrics points of body are presented as well. Injury criteria and crew threat levels resulting from explosive load under a vehicle and its close area are outlined. The aim of such a complex analysis of shock wave load over wheeled military vehicles and their crews is the development of modern and effective protection devices.

Abstract:

<p>The objective of the study is to evaluate the performance of various semi-active suspension control strategies for 8x8 multi-axle armoured vehicles in terms of comparative analysis of ride quality and mobility parameters during negotiation of typical military obstacles. Since the cost, complexity and time precludes realisation of actual system, co-simulation technique has been effectively implemented for this investigation. Co-simulation combines advanced virtual prototyping and control technology which offers a novel approach to investigate the dynamics of such complex system. The simulations for the integrated control system along with multi body model of the vehicle are carried out for the control strategies, viz. continuous sky hook control, cascade loop control and cascade loop with ride control and compared with passive suspension system. The vehicle with 8x8 configuration is run on the real world obstacle profiles, viz. step, trench, trapezoidal bump and corrugated road and the effect of control strategies on ride comfort, wheel displacement and ground reaction is presented. It is observed that cascade loop with ride control in semi-active mode offers better vehicle ride comfort while crossing the said obstacles. The improved performance parameters are achieved through stabilisation of heave, pitch and roll motions of the vehicle through outer loop and isolation of vehicle level uneven disturbances through the fuzzy logic controller employed in inner loop.</p>

Abstract:

Mass properties such as the centre of gravity location, moments of inertia, and total mass are of great importance for vehicle stability studies and deployment. Certain parameters are required when these vehicles need to be arranged inside an aircraft for the carrier to achieve proper mass balance and stability during a flight. These parameters are also important for the design and modelling process of vehicle rollover crash studies. In this study, the mass properties of a military armoured vehicle were estimated using hoisting and pendulum method. The gross total weight, longitudinal and vertical measurements were recorded by lifting the vehicle using a mobile crane and the data were used to estimate the centre of gravity. The frequency of vehicle oscillation was measured by applying swing motion with a small angle of the vehicle as it is suspended on air. The centre of gravity and mass moment of inertia were calculated using the vector mechanics approach. The outcomes and limitations of the approach as discussed in details.

Abstract:

A line-of-sight stabilised sighting system, capable of target tracking and video stabilisation is a prime requirement of any armoured fighting tank vehicle for military surveillance and weapon firing. Typically, such sighting systems have three prime electro-optical sensors i.e. day camera for viewing in day conditions, thermal camera for night viewing and eye-safe laser range finder for obtaining the target range. For laser guided missile firing, additional laser target designator may be a part of sighting system. This sighting system provides necessary parameters for the fire control computer to compute ballistic offsets to fire conventional ammunition or fire missile. System demands simultaneous interactions with electro-optical sensors, servo sensors, actuators, multi-function display for man-machine interface, fire control computer, logic controller and other sub-systems of tank. Therefore, a complex embedded electronics hardware is needed to respond in real time for such system. An efficient electronics embedded hardware architecture is presented here for the development of this type of sighting system. This hardware has been developed around SHARC 21369 processor and FPGA. A performance evaluation scheme is also presented for this sighting system based on the developed hardware.

Abstract:

Many of the high-mobility wheeled vehicles used by the British Army employ permanent all-wheel drive transmission systems with just one transverse differential. Since all the wheels on each side of the vehicle rotate at the same angular velocity severe transmission wind-up can be developed on roads. The possibility of using viscous couplings to alleviate this problem has been investigated by computer simulation backed up by practical trials on a 4 × 4 armoured reconnaissance vehicle. The results suggest that with a suitable choice of coupling characteristic this solution can dramatically reduce the wind-up torque during low-speed manoeuvres with no significant effect on off-road mobility or handling on roads. It can reduce the wind-up caused by non-uniform tyre wear but not to the extent anticipated. To safeguard handling stability under heavy braking there may be a need to bias the brake effort distribution to the front.

Abstract:

Povzetek V članku je predstavljen poseben izziv, ki mu je, po mnenju avtorja, izpostavljena Slovenska vojska z novim paketom ciljev zmogljivosti 2017. Ta namreč predvideva vzpostavitev srednjih bataljonskih bojnih skupin (SrBBSk) z vozili, ki so opremljena s 30 mm topom. Srednja bataljonska bojna skupina predvideva opremljenost z oklepnimi transporterji, zato njeno bojevanje temelji na manevru izkrcane pehote, ne pa na samostojnem bojevanju vozila, ki pehoto izkrca le, če je treba. V tej luči vsebuje opremljanje vozil s 30 mm topom nekaj strokovnih neznank. Menimo, da bo treba za take srednje BBSk najti drugačne doktrinarne rešitve, ki pa jih v Slovenski vojski trenutno nimamo. Nekatere možnosti predstavljamo v tem članku. Ključne besede Slovenija, Slovenska vojska, srednja pehota, srednja bataljonska bojna skupina, bojno vozilo pehote, 30mm top Abstract This article highlights a specific challenge brought into the Slovenian Armed Forces with the latest NATO Capability Targets 2017. This calls for the delivery of Medium Infantry Battalion Groups, equipped with Infantry Fighting Vehicles (IFVs) mounted with cannons. The Medium Infantry Battalion Group, according to the latest NATO capability codes and capability statements (2016), is to be equipped with armoured personnel carriers; consequently its manoeuvre is based on dismounted infantry and not the vehicle. In light of that, equipping the Medium Infantry Battalion Group with a 30mm cannon presents some issues. We need to have a clear doctrinal answer on its employment. Some of the options are presented in this article. Key words Slovenia, Slovenian Armed Forces, medium infantry, medium infantry battalion group, infantry fighting vehicle, 30mm cannon
