“…Their results revealed that the longitudinal creepage can lead to corrugation with a non-proportional variation of wavelength with vehicle speed, which is very close to the field measurements. The research studies by Ciavarella and Barber (2008) and Afferrante et al (2011aAfferrante et al ( , 2011b concluded that it is critical to include the wheel inertia in analyses of corrugation.…”

Rail corrugation is very serious in Cologne egg fastener track; effective control measures are still lacking. The cause of the corrugation wear on a curved metro track is analyzed based on the friction-induced vibration theory. A finite element model is established to study the frequency domain and time domain features of the friction-induced oscillation of this system. The influences of the fastener spacing and the fastener support length on the corrugation wear are investigated to develop countermeasures. The simulation results show that the friction-induced vibration of the wheel-track system is the wavelength-fixed mechanism of the corrugation wear of rail of the curved Cologne egg fastener track. There are two reasons why the low rail corrugation wear is more serious. The contact resultant force between the low rail and the wheel is obviously bigger than that between the wheel and the high rail, resulting in a higher wear rate of the low rail. The contact force fluctuation of the low rail caused by the friction-induced vibration is more severe, resulting in a higher corrugation wear evolution speed on the low rail. The friction-induced oscillation cannot be eliminated only by adjusting the fastener support length and spacing. However, the long-wavelength corrugation wear instead of the more harmful short-wavelength corrugation wear can be produced by adjusting the fastener support length and the fastener spacing to alleviate the influence of corrugation wear on the vehicle-track system.

“…In more recent papers (Afferrante and Ciavarella, 2009a, 2009b, 2010Afferrante et al, 2011aAfferrante et al, , 2011b important advances in the comprehension of the 'enigma' of short-pitch corrugation were done. In particular, it was shown that the short-pitch corrugation can exist at a 'resonance-free' regime (probably due to a sort of a contact resonance and not to any resonance in the system) for rails with continuum supports and at the pinned-pinned resonance regime, as suggested also by Grassie (2009), for rails with discrete supports.…”

The combination model of the vehicle and ladder track system that accounts for the wheel–rail interface has been developed to analyze the wheelset and ladder track vibration characteristics in the frequency and time domains. In the wheel–rail interface, the vertical contact is represented by contact stiffness derived from the Hertz theory of normal elastic contact, and lateral contact is idealized by linear contact used Kalker linear rolling contact theory. The considerable noise and vibration frequency of the ladder track is determined by experimental investigation results. Then the effect of the most significant ladder track parameters on the track vibration is analyzed in time domain using the vehicle–track coupling model. Based on the results of the parametric study, an optimization of the mechanical properties of the ladder track to reduce the track vibrations is performed using the multipoint approximation method. The results of the optimization are presented and discussed.
