"Along with the raise of speed of railway traffic (up to 300 lan/h) the claims on the reliability of braking systems go up quickly. The increase of adhesion braking systems performance brings to pass numbers of phenomena, which are necessary to solve. Most important from the ones are these: - problems of the mutual co-operation of braking systems on the vehicle - increased mechanical stress of brake modules - limit adhesion conditions between wheel and rail - high heat loading of function brake modules and consequently creation of heat cracks - deterioration of dynamic behaviour of the vehicle system. The problem will be solved with help of the computers simulation of braking, including mathematical model, which researchs the observation and the optimum solution of phenomenons mentioned above. Furthermore the model of the optimum co-operation of brake systems on the vehicle will be project. Also the project includes the construction of testing equipment for discovering of real braking ahara"@en . . "Optimalization and cooperation of rail vehicle brake systems"@en .
