Learning outcomes
|
The aim of the course is to introduce the theory and design of braking systems of rolling stock. The individual chapters focus on the force acting on the vehicle during braking, the pneumatic and mechanical part of the brake, the construction and properties of individual types of brakes. The design of a brake for a specific type of rolling stock is also part of the explanation.
Students are able to orientate themselves in the problem of brakes and to design the concept of brake equipment for rail vehicles.
