Opis:: The paper presents a study on concept of ultra-light vehicle created by innovatory technology with laminate panels what provided low weight of self-supporting body and in consequences low vehicle weight. The usage of panels with aluminum honeycomb core and glass fiber based skins allows creating large flat surfaces for interior and vehicle body without any additional treatment. Glued panels with aluminium core make closed, rigid structure of self-supporting body with relatively low weight. Independent suspension system which components are made of carbon fiber also guarantees low weight. Vehicle is powered by two electric motors BLDC type with power of 2 kW each, and they are placed in rear wheels. Low vehicle weight has important meaning, particularly for electric vehicles and its range. Presented vehicle belongs to L6-e category and does not require any licenses for driving. The vehicle is dedicated for disable people on wheel chairs. The fundamental problem for disable people on wheelchairs is getting inside a vehicle without any help. Proposed solution at the conceptual vehicle allows for getting the wheel chair inside the vehicle by the use of lower part of the rear door and the wheel chair play a role of the vehicle seat. Such solution also makes that the level of physical disability has no influence on auxiliary devices used for vehicle driving.

Opis:: Transport pertains to all functional areas of the State’s activities on every administrative level. Road transport is a very important branch of global economy and constitutes a part of the logistics network. It pertains to the transportation of cargo, items, and people. Cooperation between the branches of civilian transportation and military logistics must be the focus of continuous improvement efforts. Enhancements in this respect can serve to avoid possible failures and disruptions. The quality and availability of infrastructure plays a significant role, not only with respect to civilian, but also military assets. The condition of the vehicle is important for the safety of road transport. The provision of transport services in a military unit should mainly rely on military-civilian cooperation and effective communications. The condition of the means of transportation has been indicated as a factor influencing transport safety. Employing new technology and solutions enables constant improvements to the diagnostic system, broadening the knowledge and enhancing the skills of the motor vehicle driver in terms of proficiency in operating and maintaining the vehicle used.

Opis:: Selected experimental research results of truck tire in steady-state side cornering and transient cornering conditions are presented in this paper. Experimental research results of the tire have been used in simulation research of medium duty truck in nonlinear driving conditions. The paper presents the structure of the vehicle dynamics model and a description of applied tire-road interaction model. Simulation research of the vehicle lateral dynamics has been performed in two variants: without and with the model of tire relaxation. During research, the tire relaxation length has been also changed. The steering wheel angle changes were forced as continuous sinusoidal excitation signal with a constant amplitude and with continuously increasing frequency. There have been analysed basic physical quantities characterizing the vehicle lateral dynamics connected with the vehicle active safety, especially including body yaw velocity and lateral acceleration in the centre of the truck body mass. An analysis of research results have been performed in the time and frequency domain. Time courses of analysed physical quantities and their frequency spectrum, obtained for tire-road interaction model without and with the tire relaxation (with different values of relaxation length) have been compared. Based on the simulation research results there have been considered the influence of tire relaxation on the vehicle performance. There have been shown that the tire relaxation can significantly change courses of observed physical quantities connected with vehicle lateral dynamics connected with vehicle driving safety.

Opis:: The road safety is affected by several factors quality of infrastructure, behaviour of drivers, including their proper training and also safe cars. For the safety of vehicles in the approving process a number of regulations (regulatory acts) apply, regulating the technical requirements in the active and passive vehicle safety, but also in the environment. In the area of technical requirements for vehicles and their parts significant changes occur constantly, mainly due the progressive technological developments. A large number of regulatory acts are often changed due to the tightening. These regulatory acts relates directly to manufacturers, because their manufactured vehicles have to meet these requirements. That these regulatory instruments are evolving in the right direction proved the fact that due to better road safety the number of fatal accidents in the last two decades shrunk, although the volume of traffic has tripled. A significant progress has been achieved only through the improved vehicle safety and only in a small measure thanks to the improvement and upgrading of the infrastructure.

Opis:: The paper presents experimental validation of numerical flow analysis around tracked amphibious military vehicle. The aim of the study was to validate the simulation results and visualize the flow around optimized geometry To perform numerical simulations, a Computational Fluid Dynamics code FLUENT was used. The software is dedicated to model flow, turbulence, heat transfer, and reactions. The area was divided into two domains – air and water. During the simulation, water was moving with speed specified in standardization. However the numerical techniques are constantly developed and improved there is still a strong need for verification especially in buoyancy analysis and water performance evaluation. Results showed quite good agreement with literature after some modifications of the model. Then the flow was numerically visualized. That allowed in-depth analysis of the flow around each of vehicle's parts and some major and minor modifications were proposed. Modified geometry was analyzed and obtained results will be compared with previous ones. Additional stability and manoeuvrability tests were conducted. The results will be used to modify the geometry of vehicle and conduct experimental tests to verify the numerical code performance and check the actual change in vehicle's water performance. Future work will also consider propeller influence on results.

Opis:: In the near future, vehicles will be moving autonomously with little participation or completely without the driver affecting on the vehicle move. Task of driver will be limited to identify the end point of the vehicle route. Vehicles, to meet this challenge, must be equipped with the control systems and supervising the movement of the vehicle, reacting onto the movement of pedestrians and other vehicles, road signs, time of day and weather conditions. The movement of the vehicle will be controlled and driven by a system on board a vehicle, but will also be required to tracking the vehicles position and its movement parameters using of the vehicle satellite navigation systems. In addition, the motion trajectory of the vehicle will be determined and any deviation from the target track will be corrected. The article presents a proposal for determining the trajectory of the vehicle based on the control points specified by the coordinates of the location of the vehicle and ways of correcting the trajectory of the vehicle. For this purpose was utilized the vehicle in scale.

Opis:: In this paper a numerical model of a terrain vehicle suspension system development process is presented. In the performed studies the suspension system with and without a simplified motor-car body was taken into consideration. Geometry of the tire, wheel and system elements were achieved using reverse engineering technology. Moreover, with the assistance of a microscope and an X-ray device it was possible to achieve the exact tire cords pattern, which in the next stages was implemented into the FE model. Subsequently, numerical simulations of both cases were performed simulating the TNT explosion under a wheel. The non-linear dynamic analyses were performed using the LS-DYNA code. To solve both presented cases the explicit central difference scheme with modified time integration of the equation of motion was implemented. Computations of blast wave propagation were carried out with the Smooth Particle Hydrodynamics (SPH) method with Jones Wilkins Lee (JWL) equation of state defining the explosive material. Obtained results have shown different suspension system elements damage and tire destruction characteristic, which come from blast wave reflection of the motor-car body surface.

Opis:: The aim of the article is focused on assessing the degree of end-of-life for the vehicle front suspension beam. The first stage of the problem taken was represented by a road test of the vehicle at distance expressed by 100.000 km. Following the end of the operation tests, the suspension beam was dismantled and subjected to laboratory tests. The tests demonstrated numerous beam top layer plastic deformations, which came into being as a result of the vehicle driving onto an obstacle on the roadway or onto raised road infrastructure elements. At the point of connection of the stabiliser rod to the beam, surface degradation was noted, which consisted in the considerable change of the surface profile, hardness reduction and the grey and dark brown colour. Corrosion regions and fretting wear traces were noted. Corrosion pits, scratches and material build-ups was observed. The analysis of the chemical composition of wear products demonstrated the presence of elements such as iron, oxygen, chlorine and silicon, as an effect of operational conditions.

Wydawca:: Instytut Techniczny Wojsk Lotniczych
Tematy:: transport

railway vehicle
Opis:: The article presents the methodologies based on multi-body systems used to analyze the dynamics of rail vehicle in motion in a straight line. Study of the railway vehicles dynamics requires the creation of three mutually independent models: the model of the vehicle, the track model and a model of the wheel - rail contact. A railway vehicle model developed in the multi-body systems convention was an electric locomotive of the EU07symbol The general software model of the wheel - rail contact was programmed and is presented, which allows one in the course ofanalysis to determine the coordinates ofthe contact point between wheel and rail and thus the designation of the wheel forces in contact with the rail. The model ofthe contact forces includes normal force with damping hysteresis and tangential forces determined by the Polach method. Developed models were implemented in Matlab program environment. The numerical simulations were performer for the complete vehicle and a single bogie steady state conditions.

Opis:: Today's world mainly focuses on reducing human effort and maximizing efficiency. Machines are replacing humans in many hazardous working environments. Automation is playing an important role in saving human efforts in most of their day-to-day works. A robotic vehicle has been developed in this project which can be particularly used in a small scale industry. The robotic vehicle is controlled by a mobile phone that is connected to the robot through a GSM network which acts as a remote controller. DTMF technology is used, which enables the robot to be controlled over the GSM network. The keypad of the mobile phone acts as a remote to control the vehicle's movement. The robotic vehicle developed is not an Automated Guided Vehicle (AGV) as an operator has to manually operate the vehicle. A sensor is attached to the front of the vehicle which senses obstruction in its path and enables the vehicle to avoid collisions with moving or fixed objects. The vehicle features battery powered motors and computer technology that has been programmed to drive to and from specific points. This research work involves the fabrication of a working model vehicle controlled over a GSM network using DTMF technology. The guided vehicle can work in environments such as transporting materials from a warehouse to production lines to reduce human effort and increase efficiency.

Opis:: Artykuł zawiera projekt 3D jednokołowego pojazdu osobowego, zasilanego z akumulatora, który autonomicznie zachowuje równowagę w kierunku ruchu pojazdu oraz w kierunku poprzecznym do ruchu. Cały proces zachodzi dzięki opracowanemu rozwiązaniu przesuwu mas za pomocą układów balansu. Nadawanie prędkości realizowane jest za pomocą manetki zamontowanej do kierownicy pojazdu. Modelowanie przeprowadzono wykorzystując program Solid Edge ST5.
The article includes 3D design 1-wheel passenger vehicle, powered by a battery that autonomously creates a balance in the direction of the vehicle and in the direction transverse to the movement. The whole process takes time thanks to mass displacement termination agreements with the balance. Transmission speed is achieved by means of shift paddles mounted to the steering wheel. Modeling was performed using Solid Edge ST5.
