Selected Simulation and Experimental Studies of the Heat Transfer Process in the Railway Disc Brake in High-Speed Trains

The effectiveness of railway brakes strongly depends on their thermal condition. A computer simulation and experimental investigations a full-scale dynamometric stand were chosen as an adequate analysis the heat transfer process in brakes. article introduces two-dimensional, axisymmetric numerical model tested disc brake. Boundary conditions related to generated friction brake transferred environment are also presented. transient problem was solved using in-house program finite element method. presents simulations intensive braking train with initial high speed. Temperature responses surface at other selected points shown. In addition, imaging camera used assess temperature distribution disc. results tests preliminarily compared. Similar maximum values obtained end particular discrepancy during analyzed process.
