WHEEL-RAIL CONTACT STRAIN
EFFORT AU CONTACT RAIL-ROUE
Corrugation of rail appears mostly (but not only) in the sharp curves and consists in quasi-periodic irregularities on the running surface of the rails. The main points of the research developed in the RATP (Paris Transport Authority) about this phenomenon are presented in this paper. As metallurgical investigations of rail samples indicated that corrugation seems to be due to fatigue type phenomena a computation of wheel-rail forces was developed. The forces have been separated in two parts: the "quasistatic" forces corresponding to steady-state curving of the bogie in the curve and the dynamic forces due to irregularities on the rolling surface of wheels and rails (roughness). The use of transfer functions to evaluate wheel-rail contact dynamic forces allowed us to compute the force transmitted to the ground as a function of frequency, for a given wheel-track system. This is a way to qualify the ground vibration due to the system for given characteristics (masses, stiffnesses, damping.).
