Originální abstrakt

The goal of this study was to investigate the effect of climatic conditions on adhesion in the wheel-rail contact. For this purpose, a ball-on-disc tribometer was utilized which enables to precisely control climatic conditions, mainly temperature and air humidity. Apart from these conditions, the influence of leaf layer on adhesion was investigated. The special attention was paid to water condensation which can cause a further adhesion decrease. Obtained results showed that a combination of high relative humidity and a presence of leaf layer can significantly reduce adhesion in the contact, even below a value 0.1 which is needed to traction and braking.
