Design of dosing unit for sanding of rail vehicles
 Szabari, Šimon ; Čížek, Petr (referee) ; Omasta, Milan (advisor)
This master thesis deals with the development of a sanding unit for rail vehicle. The aim is to develop a dosing device capable of applying sand to the contact of a wheel and a rail depending on the speed of the vehicle with the detection of the flow rate of the applied amount. The application of sand or alternative materials to the wheel-rail contact is an effective way to increase the traction of driving rail vehicles. During the development, there was a cooperation with a company engaged in the production of equipment for rail transport. During the work, experimental development was applied, during which a pneumo-mechanical dosing unit with control of the applied amount of sand was designed and tested. Simultaneously with the dosing unit, a sand box was designed that is suitable for the type of rail vehicle for the purpose of tests in real operation. The pre-prototype design has the potential to bring improvements in several areas of sanding systems.

Design of rail vehicle sanding systems
 Balounová, Hana ; Šperka, Petr (referee) ; Hartl, Martin (advisor)
The bachelor thesis deals with creating an overview of sanding systems, which are available on the marketplace in terms of their construction. Sanding devices are used in rail transport to incerase the adhesion during braking and moving off in bad weather condition. The thesis inculdes findings of testing influences of construction on the quality of sanding, list of companies producing sanders and their products and defining the future development trends.
