Friction Induced Oscillations and Material Degradation in Railway Engineering
Journal Title: Machine Dynamics Problems - Year 2018, Vol 42, Issue 1
Abstract
Maintenance of tracks and vehicles is an important factor for security and passenger comfort. Late and insufficient repairs may have an accelerating effect on the degradation of a railway system’s quality. In the present paper, some phenomena related to the dynamics of running railway vehicles in the presence of geometric imperfections of rails are explored. In particular, the sensitivity of frictional forces to imperfections of contact surfaces is analyzed, and consequences for the propagation of defects are discussed.
