Wireless transmission of measurement data directly from the sensor on the chassis to the vehicle: The operational conditions and the available technologies have been recorded. A concept for a prototype has been developed for a defined measuring range, which will also be transferable to other measuring fields in order to be able to use the solution comprehensively on all measuring runs.

Track closures are based on fixed processes that guarantee the highest level of safety. However, if these processes are abbreviated due to negligence or lack of time, a considerable risk arises for the railway maintenance workers involved. This is especially the case when material is transported by rail into the closed track and thus a journey takes place in what is actually a closed track. The aim of this project is to find technical or organisational solutions to increase safety in the closed track.

Sub-project commissioned by the German Federal Ministry of Transport and Digital Infrastructure for an overview of railway research and current research in Germany and other EU countries conducted since 1990 : The results are listed in a database, indexed and analysed with regard to their topicality and future orientation. Based on this, research priorities will be identified, from which further research needs can ultimately be derived.
Nowadays, steel frames for bogies of rail vehicles are mainly welded. Due to the large-area welds and the thickness of the material, distortion of the bogie frame occurs. This requires more complex reworking in order to achieve the required tolerances when assembling the components of the bogie. For this reason, the result of the welding process is to be simulated. Within the welding simulation, the focus is to be placed on the structural simulation.
The aim of the investigation is to predict the welding distortion on individual parts and bogie frames. With the information gained, the distortion can be minimised and reworking can be reduced or completely eliminated. In the end, an optimised welding plan is to be drawn up, into which the results of the investigation have been incorporated.

Analysis and evaluation of vehicle and test stand measurements with regard to the braking behaviour of vehicles or the test specimen and their anti-skid activity. The aim is to measure adhesion values in the presence of different intermediate media that can lead to reduced braking performance and to compare the vehicle data with those of the test rig. The results will be incorporated into a cadastre that will bundle a compilation of different conditions and provide the basis for a real-time analysis of the track condition in the future.
Sebastian Skorsetz, Voith Turbo GmbH & Co. KG
Investigation of the failures of gearboxes in test bench trials with the help of measurement data and methods of analysis of reliability technology for possible causes of failure: Due to the insufficient informative value of the available measurement data, a recommendation was made to record additional measurement values and modify test runs.

Sub-project within the framework of a feasibility study to determine the energy requirements for a tram. The conditions for the inductive transmission of the required energy quantities for the journey over a model route of 11 km length with corresponding intermediate stops were recorded.

Installation and practical testing of a collision warning system with sensor components from the automotive industry in rail vehicles: Due to the original area of application in road traffic, the system is particularly suitable for trams and light rail vehicles running flush with the road with their low speeds. For the test during operation and the analysis of possible malfunctions, SSB AG provided a light rail vehicle as a technology carrier and Bosch Engineering GmbH provided the associated software and hardware.
