Research Projects


VÚKV a.s. has taken active part in many research projects of the Czech Republic and other European countries, including but not limited to:

Methodology of creating simulation models for evaluation of aerodynamic effects of vehicles (project terminated)
Abbreviated title: CKDV
Period: 2018-2019

The methodology defines the procedures for numerical simulations in the calculation of the pressure peaks induced by the passage of a train, which specify the requirements for the models given in EN 14067-4, resp. its Czech national version ČSN EN 14067-4.

Purpose: Compared to the standard, the methodology provides a broader description and explanatory comments on the requirements for geometry creation, computer network or computational model definition. Furthermore, the methodology indicates limits and effects of individual parameters in comparison with normative requirements so that it is possible to reduce the complexity of calculations during preliminary calculations, mainly used in the development phase of vehicles.
Wheel profile of trams (project terminated)
Abbreviated title: CKDV
Period: 2018-2019 
Description: Research of wheel profiles of tramway vehicles.
Purpose: Summary research report describing results of the activity in the field of research of wheel profiles of trams.
Simulations for assessment of safety against derailment of a freight wagon, stage 3 (project terminated)
Abbreviated title:  TWIST
Period:  2018
Description: Complex evaluation of present methodes for safety against derailment assessment. Project and realization of the new mobile testing equipment for carrying out of the safety against derailment and sway tests. Proposal of a new more exact method for safety against derailment demonstration. The new method was demonstrated on the new testing equipment.
Purpose: Simulation calculations of run of few freight wagons with Y25 bogies through a curve with radius of 150 m at the speed of 5 kmph. The simulations were performed at the Faculty of Transport Engineering of the University of Pardubice with using of the multi-body simulation tool SJKV. The simulation results are compared with results of measurements realized with relevant wagons in order to validate the computational model and prove its applicability for replacement of guiding force measurement (in framework of the method No. 2 according to the EN 14363 for assessment of the quasistatic safety against derailment) by means of the simulations.
 Research and development of safe tram face (project terminted)
Abbreviated title: SafeNOSE
Period: 2018-2020
Description: Front party development of a tramway with increased safety against pedestrians and to mitigate the consequence of collisions with them. The result is a timeless tramway front with modern look, design, functionality and equipment. The outer covering of a tram with comparable design which is used from Škoda Transportation was developed in this project. The developed solution gives the possibility to Škoda Transportation to solve the collision safety by means of front shaping. The solution by means of energy absorption by facing material and its fastening requiers further development in the area of plastic materials.
Purpose: The main objective of the project is to achieve increased safety for pedestrians through mitigate the consequences in the event of a collision with the front of the tram. The project also aims at influencing the development of European legislation in this area with the active transmission of knowledge from the project to a working group of CEN / TC 256 / SC 2 / WG2. Also the possible benefits of deployment of active safety systems will be assessed. Both positive and negative effects of application of such systems will be evaluated, not only in terms of pedestrians, but also in terms of the safety of passengers inside the tram and the driver.
Design and optimization of welded constructions of parts of rough structures of railcars and undercarriages of rolling stock (project terminated)
Abbreviated title: Welding optimizing
Period: 2018-2021
Description: Project, design and production process optimizing, production of front parts of intermediate car underframe. The research base is the intermediate front beam which ran through the complete process from the primary design project via simulation calculations to the welding and evaluation to the production using the optimized process. The validation using deformation measurement on a real welded piece and the comparison with the deformations predicted by simulation calculations. The evaluation proved the full compliance in the deformation direction and partial compliance in absolute deformation values. The possible causes of the partial compliance were identified by means of more detailled analysis and the suggestion for both input increasing for simulation calculation and further development in the future.
Purpose: Optimize production processes, costs and contribute to general increase of competitiveness of participating entities. Specification of optimal rules for welded designs with respect to welding technology, selected material, operational and exceptional loads. Innovation of parts of bodyshells. Innovation of weldments of chassis frames and adjacent structures. Extension of applied portfolio of materials - Al alloys,austenitic steel, duplex, thermo-mechanically treated steels and generally materials with higher corrosion resistance. Optimization of welding technology of selected structures with the aim of minimizing the degradation of material by deformations and residual stresses. Prototype of welded structure. Verified welding technology.
Josef Bozek National Center of Competence for Surface Vehicles
Abbreviated title: JOBNAC
Period: 2018-2022 

Research and development for the sustainable mobility tools as road and rail vehicles connected and networked by the transport systems, taking into account both the strategic research results for the decisive economy spheres of the Czech Republic and immediate goals of industry.

Purpose: Increasing of competitiveness at global market. The means for the achievement is the establishment of inter-sectoral consortium for a long-term synergic collaboration among academia, industry, private research, SMEs and testing companies, focused on the decisive issues of the future vehicle and mobility markets. 
Analysis of tram-pedestrian traffic collision, validation of simulation models
Abbreviated title: DUMMY
Period: 2018-2022

Increasing of tram safety with respect to pedestrians. The project will address tasks in regard to both passive and active safety. A methodology for tram-pedestrian crash tests using a testing dummy will be created. After multiple crash tests have been implemented a simulation model of tram-pedestrian collision will be created and validated.

Purpose: Effective design of safer vehicle structures. The equipment and methodology will be utilised to experimentally verify the benefits, functionality and necessity of a system of automatic braking in front of an obstacle.
Force effects measurement in the test curve 150 m
Abbreviated title: Oblouk 150
Period: 2022-2024
Description: System for measuring of forces between wheel and rail of a running vehicle with on-line output of measured the measured forces. It is a stationary system that is installed in track which can be used especially in a flat curve of a radius 150 m. Measurement of the wheel-rail forces in a curve of such parameters is required by the European standard EN 14363 for an evaluation of safety against derailment. In principle, however, it is possible to place the measuring system in any railway track in order to determine the force effects which a passing vehicle acts on this track.
Purpose: The developed measuring system will be used during the tests of railway vehicles, both homologation ones necessary for the approval of new vehicles and research and development ones. There are the tests directioned to the vehicle safety in operation and force effects of the vehicle to the track. The realisation contributes to the development of new safe vehicles with low service costs.
