AB  - For many years, methods for assessment the safety against derailment of railway vehicles have been developed and improved. Possible approaches to solve this task are conducting real in-situ measurements or the application of MBS simulations. The goal of both approaches is to reliably determine the lateral Y and vertical Q forces and their Y/Q ratio. The limit values of this ratio, which should not be exceeded, are defined by standards and in technical reports of the European Technical Committees. Based on the complex geometry of the wheel-rail contact and other parameters of the vehicle and the track, this should ensure that derailment will not occur. In the experimental approach or measurement of relevant parameters, in Europe there are several methods defined by the standard EN 14363. All of them are extremely complex and demanding in terms of conditions to be provided and logistics, so in recent times tendencies are to apply simulations. This paper presents the results of the derailment safety tests of several types of freight wagons using method 2 of EN 14363. The application of this method was made possible by the development of an original wayside system for measuring the wheel-rail contact forces and the development of a hydraulic test rig for twisting a complete wagon. The results of these tests show that some freight wagons, although with standard running gears and standard dimensions, have quite high ratio Y/Q forces during curve negotiation.

AB  - The logistical support necessary for the organization of type tests of rail vehicles is a complex task. Resources that must be provided are expensive and related to the complex organization of work in the field. On the other hand, the relevant European standards are technically more and more demanding, so the logistical support is also more extensive. In this paper, the focus is on the presentation of activities related to type tests of freight wagons. The testing of the brake system is shown in detail. For this test it is necessary to perform measurements on an open track, at different running speeds and different levels of vehicle loading. Given that the test is performed by decoupling the wagon, it is necessary to apply a number of technical measures that will ensure that the test is performed safely and with minimal risks. By applying the network planning method, it was shown that although there is a relatively small number of activities, each of them can be critical, i.e. in case of delay may cause additional costs, that can be identified during planning, but which are not recognized and most often not acknowledged by the purchaser of the testing.

AB  - The paper presents an analysis of possible causes of damage to the tread of wheels and cracking of brake blocks of heavy-duty motor tower car VMT 980 C-GR. In order to determine the possible causes, a series of tests were done to check all the influences that led to the occurrence of these damages. The  analysis included checking the regularity of the brake operation, non-destructive testing of the tread damage, and visual inspection of the brake blocks. The correctness of the brake operation was checked by stationary brake tests.
The examination of the damage to the tread of the wheels was performed by non-destructive methods, using means for detecting microcracks and measuring the hardness. The results of the conducted tests indicate that the characteristics of the brake system are within the designed limits and are not the cause of damage to the wheels and the brake blocks. The measured values of hardness on the side and on the tread are higher than the minimum required for test samples according to EN 12362. The wheels are made of ER7 steel, which is used as a standard for railway wheels, with a chemical composition within the prescribed limits. Further analysis showed that significant surface damage to the brake blocks is a consequence of previous damage to the tread surface of the wheels. Visual inspection of the wheels showed flaking and cracking, indicating contact
fatigue and the presence of thermal stresses as the most likely causes of brake blocks and wheel damage.

AB  - Draw-buff gear plays a significant role in the transmission and damping of longitudinal forces generated during accelerating and braking of trains. The role of the buffers is to protect the railway vehicles bearing structure, cargo and passengers from excessive longitudinal impacts. Especially when shunting freight wagons. For that reason, they have built-in elastic-damping elements that absorb shocks and partially convert kinetic energy into heat. This paper analyzes buffers with rubber-metal springs, which are the most often used in the freight cars nowadays. The static and dynamic force-stroke characteristics obtained by measurements on hydraulic press and during buffing impact tests are presented. These results are then compared with calculations using FEM analyses. The analyses included checking of the buffers ability to absorb a sufficient amount
of energy that can be generated during wagon normal operation and in the case of exceptional shunting impacts.

AB  - The increased capacity of freight railway traffic leads to increased noise pollution. The existing regulation TSI NOI defines the maximum noise level allowed to be emitted by railway vehicles. Consequently, the noise tests are mandatory type tests for all new vehicles. Experience from noise tests of different freight wagons have shown that measured noise level depends on many parameters and in most cases is close to the maximum permissible values. Contemporary design of the freight wagons has to be conceived such as to emit as low noise as possible. Accordingly, it is necessary to identify the main influencing sources that affect the noise generation and to find a way to reduce their influence. This paper presents results obtained by measurements of pass-by noise of a freight wagon, with wheels having different wheel tread surface roughness. It appeared that wheel-rail rolling contact as a noise source is very significant and may be critical for assessment of the railbound vehicles.

AB  - From the aspect of safety, brakes of rail vehicles are an extremely important system on the vehicle. Braking performance affects the normal functioning of vehicles and interoperability of rail vehicles in classic railway train compositions. All trains, classic and different type of motor trains must conform with the available stopping distances, which are predefined by the railway signalling, i.e. control length of a signal and depends on the maximum allowable speed for which the track section is designed. Apart from that, in classic wagons, which are combined and participate in the formation of different train compositions, mutual compatibility must be ensured from the aspect of used braking equipment and connection subassemblies, but even more important, braking performance of all wagons in the train has to be uniform within certain tolerances. This prevents weaker braked wagons from running into stronger braked ones, which can cause longitudinal jerks and may in extremes lead to a train rupture. Stopping distance during brake application depends on train braking performances, longitudinal running resistance and presence of wind and its direction. This paper deals with the influence of wind conditions on the results of slip brake tests and the estimation of a single vehicle's braking performance. Based on experimental measurements, simulations using CFD and comparison with the obtained results, this paper proposes a possibility to extract air drag resistance and wind force from the total resistance force. Presented methodology and obtained results may serve for further simulations of aerodynamic characteristics apart from braking performance, such as vehicle running resistance, energy consumption, etc. and for optimization of the wagon shape and design.

AB  - Wheels for rail vehicles are made according to precisely defined geometry and dimensions. The wear of the 
wheel profile in operation is not uniform, so the initial profile changes. It is a consequence of the inevitable 
slippage, which is influenced by a large number of factors. Certain changes in the profile can be important for 
the safety of movement and riding quality, so the shape of the profile in operation must be regularly checked 
through characteristic dimensions measurements: the flange thickness, the flange width and its slope. 
Changing the characteristic measures can lead to: thinning of the flange over the allowed limit, which can lead 
to its cracking, increase in the height of the flange, which can cause problems with derailment at crossings and 
switches, reducing the slope of the flange, which can lead to derailment on the switch tongue. The paper 
presents the verification of the dimensions and shape of the pattern for control wheel profile for the type of 
tread shape S1002, which are used to control the wheel profile after reprofiling. The dimensions of the S1002 
wheel profile are given in EN 13715 on the basis of which the control patterns are made. After making the 
pattern or the control accessories, its dimensions were checked by scanning on a 3D scanner Atos core 200. 
The resolution of the scanner is 0.08 mm, and its working surface is 200 x 150 mm. The 3D model was obtained 
by scanning, from which the coordinates of the scanned profile were obtained with the help of the GOM Inspect 
software package. Based on these coordinates, a comparison was made and a deviation from the nominal 
profile.

AB  - Railway vehicle “Avenio” is a Siemens low-floor tram model. One of the steps towards the successful 
production of this tram is reflected in the optimal production of each sub-assemblies and element. The most 
important aspect of the development and production of elements is the safe operation of the vehicle system 
and comfort drive during exploitation. In addition, it is necessary to take into account the cost-effectiveness of 
its manufacture as well as maintenance costs. In order to reduce the production and maintenance costs of the 
whole system, the production of one of the components of this tram that is called a “tilt stabilizer” was optimized. 
This element has a very important role within the vehicle construction because it controls the inclination of the 
vehicle body in relation to the bogie around the longitudinal axis. This way reduces the discomfort to 
passengers caused by centrifugal force and prevents further narrowing of the vehicle profile. The primary 
design of this assembly is based on the welded construction. The device consists of 4 mechanical elements 
built into the tram structure. Bearing in mind that welded construction characterizes a higher cost of production, 
the idea was to design subassembly for the production on a numerically controlled machine and to successfully 
replace the current method of production in this way. For the newly adopted solution of the model, a static 
strength calculation was made which determined that the tested model satisfies the load conditions that occur 
in the structure. Static strength analysis was performed by finite element method in the "Ansys Workbench" 
software package, according to the criterion for equivalent "von - Mises" stresses. Results showed that 
modified structure and applying of new production method give absolutely acceptable assembly with requested 
strength and significantly lower life cycle costs.
