... generation of ultrasonic frequencies through surface roughness. The hypothesis is that the excitation of such high frequencies originates from sliding friction components in the contact patch between wheel and rail in conjunction with well-known sinusoidal tracing. Consequently, if this hypothesis holds true...

.... The implementation of this regularization is presented through two examples in which slip-stick motion induced by sliding friction is of primary importance. The first is a simple one degree-of-freedom system and illustrates the existence of nontrivial equilibrium states. The second example is a multi-degree...
