Bainitic steel for dynamically loaded components
The project is aimed at designing the constitution of bainitic steel for dynamically loaded components (especially a switch crossing) with regard to its resistance to high (dynamic) contact loads and wear, fatigue and brittle fracture resistance. At the same time the proper design and optimization of this steel are conditioned by the specification of the critical phases of damage to a component and the corresponding characteristics of fatigue and a brittle fracture that are also a subject of this project. In the first phase of solving it is assumed to design the constitution of low-alloy cast steel and to verify their properties in terms of extreme and combined dynamic loads. In the next part of the project it is crucial to select and specify parameters for assessing the integrity and life of a crossing on the basis of detecting the presence of a defect in the component. The final part of the project is to assess the effects of metallurgical quality and possibly also welding in terms of fracture properties and integrity on the basis of bases obtained during the early stages of solving the project. (2002-2004, GA106/02/0745, CZK 2,702,000)

 

        

Increasing the quality of track in switches by flexibility
The railway switch is by the nature of its function a critical point of railway lines in terms of dynamic effects resulting from the passage of vehicles. The limitation of these effects between vehicle wheels and rails is the most effective way to improve the quality of rail transport on the part of vehicles, a line and passengers (service life, reliability, operating costs, and performance parameters such as speed, noise, safety, energy consumption, and ride comfort). Therefore, the project is aimed at designing an engineering solution for a railway crossing structure with the flexible fastening of rails for the mounting on gravel ballast and slab track options, its review and verification by prescribed laboratory tests by 12/2012 and by validating on a line, including the appropriate measurement, which is assumed to be completed by the end of 2015. The outputs must meet the interoperability requirements according to the relevant TSI, EN and certificates. The solution will be used in the Railway Infrastructure Administration network (SŽDC), in the Railways of the Slovak Republic network (ŽSR), and for export activities.

Centre for Effective and Sustainable Transport Infrastructure (CESTI)
The CESTI project is aimed at technical innovations solving deficiencies in today’s transport infrastructure. It deals with road and railway infrastructures, including bridges and tunnels. It solves environmental issues, aspects of safety and reliability of constructions and effective infrastructure management systems with applying performance parameters in a cross-sectional way. The project reacts to the requirements of cost efficient, material and energetically sustainable, technically durable, reliable, and permanently available transport infrastructure.For more information please see www.cesti.cz.
