In this article, a systematic numerical optimization of brake discs for railway vehicles with computer-aided engineering tools is presented. The main design parameters of brake discs were defined. One-way fluid-structure interaction analysis was performed. Computational fluid dynamics soft- ware tools were used to calculate heat transfer coefficients, which were transferred into thermal transient finite element method analysis to predict brake disc temperatures during different braking scenarios. Systematic analysis of defined design parameters was made. With the help of computer-aided engineering and numerical parametric design, it was possible to design and analyse several innovative designs for brake discs, which enables energy and material savings.
