Modeling estimates temperatures and deformations in brake systems and contact wire interactions, suggesting improved design safety.
The use of mathematical and computer models to analyze the durability of components in railway rolling stock brake systems and “pantograph — contact wire” systems is considered. A theoretical model is presented that enables temperatures generated in block brake components during prolonged braking to be evaluated. Finite element analysis is performed to estimate plastic deformations in disc brake components when the brake is applied. A coupled finite element model of the interaction between the current collector insert and the contact wire is developed to allow determination of the temperatures and mechanical stresses in them when the vehicle is in motion.
