| Abstract: | A certain number of railway brake discs made of gray cast iron, showed the presence of small cracks only after a few thousand
kilometers. To investigate main causes of a brake disc failure, numerical analysis was done by using ABAQUS software. Numerical
analysis resulted from a physical model of heat flux in dependence of braking time. Physical model was applied considering
all demands and presumptions given by industry representatives. |
