The design of the test equipment for influencing the adhesion of the contact wheel and rail
 Kejda, Petr ; Pavlík, Jan (referee) ; Bradáč, František (advisor)
This thesis aims to design a test equipment for positive change the adhesion contact between the wheel and the rail head. This can be achieved by changing the size of the coefficient of friction, which are eliminated negative effects accompanying the operation of the rail transport (acoustic emissions and excessive wear). Reducing friction must not be compromised traction or braking. Equipment ranks among to Top of Rail systems where as medium is used the friction modifier. The study includes an overview of available types of friction modifiers and applicators Top of rail system. The design of the applicator is built based on the off-board system that is placed in front of the arc track with a small radius of curvature.
