“…The error con- tributions from other wheelset eigenmodes (with or without axle bending) seem to be smaller and restricted to narrow frequency bands. The instrumented wheelset technology and the assessment of contact forces are discussed in detail in the accompanying paper [4]. The solution is based on an extended state-space vector approach, and a complex-valued modal superposition for the linear track model with non-proportionally distributed damping.…”

“…Figure 2(a) shows the arrangement of strain gauges on a Japanese conventional special instrumented wheelset, so-called 'PQ wheelset', and (b) shows its outlook. Although various new measuring systems have been developed in Western countries and Japan [2][3][4], every system needs strain gauges and has not solved the problems mentioned above. …”

Summary. This paper features a method to synthesize the track irregularities, by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method thus suggested allows a convenient formulation of the limits of the interval specific to the wavelengths of the track lateral irregularities, so that it will be representative for the frequency range of the vehicle lateral vibrations. The Part I of this paper demonstrates the method to synthesize the track alignment and its basic elements -the power spectral density of the track irregularities, as per ORE B176 and the values associated with the track quality levels, mentioned in the UIC 518 Leaflet. The Part II introduces the results of the numerical simulations regarding the dynamic behaviour of the railway vehicle during the circulation on a tangent track with lateral irregularities, synthesized as in the method herein.
