Periodic structures exhibit unique band gap characteristics by virtue of which they behave as vibro-acoustic filters thereby allowing only waves within a certain frequency range to pass through. In this paper, both lateral and vertical flexural wave propagation and vibration control of a periodic railway track are studied in depth. More precisely, a rail fastened on rigid sleeper blocks is modeled with an Euler-Bernoulli beam. The dispersion relations in both lateral and vertical directions are obtained using the Floquet-Bloch theorem and the resulting dispersion curves are verified using finite element (FE) models. Afterwards, tuned mass dampers (TMDs) with different mass ratios are designed to control vibrations of the examined rail along both lateral and vertical directions. Moreover, the influence of damping of rail and resonators on band structures is investigated. As a replacement to the conventional TMD, a novel possibility to control vibrations relies on using another rail as a lateral distributed resonator (LDR). Although the effectiveness of LDR is lower than that of localized resonators, the former represents a simple and promising way to control vibrations. Efficacy of the proposed control methods is finally verified using the results of transient simulation based on a random Gaussian white noise input.

“…Thompson et al 17 and Wu et al 18 studied the optimal vibration absorber parameters under different conditions. Jin et al 19 developed a tuned particle impact damper, in which the vibration energy was dissipated through particle impact. However, most of the above devices used only a single energy consumption mechanism, and could not be designed for both broadband and specific-frequency band vibration suppression.…”

Rail corrugation increases the intensity of interaction between the wheel and the rail, make the vehicle and track vibrate more strongly, and increase the rolling noise. Based on the fixed corrugation wavelength mechanism, this paper determines the required corrugation wavelength to be controlled using field investigations. A new type of corrugation suppressor is developed that combines a dynamic vibration absorber and a labyrinth damper. The purpose of the suppressor is to realize wide-band vibration resistance and energy consumption, and to control the vibrations in a specific frequency band. By analyzing the vibration transmission characteristics of a typical small-radius curved subway track, it is verified that the device can flatten the rail dynamic response function, suppress the pinned-pinned resonance of rail, and increase the transmission attenuation rate of rail vibrations. A coupled rigid-flexible model of vehicle and curved track is established. The rail vibration and corrugation growth rate before and after installing the suppressor are compared. The suppressor can reduce the 1000 Hz vibrations by 10.1 dB and decrease the medium and high frequency vibrations of the rail by 5.6 dB. At the same time, it can attenuate the rail corrugation growth rate near 500 Hz and between 700-1000 Hz. A field tracking test showed that the suppressor can effectively inhibit the initiation of 15-30 mm wavelength corrugation.

Periodic structures exhibit unique band gap characteristics by virtue of which they behave as vibro-acoustic filters thereby allowing only waves within a certain frequency range to pass through. In this paper, lateral and vertical flexural wave propagation and vibration control of a railway track periodically supported on rigid sleepers using fastenings are studied in depth. The dispersion relations in both lateral and vertical directions are obtained using the Floquet-Bloch theorem and the resulting dispersion curves are verified using finite element models. Afterwards, tuned mass dampers (TMDs) with different mass ratios are designed to control vibrations of the examined rail in both the directions. Moreover, the influence of damping of rail and resonators on band gap characteristics is investigated. As a replacement to the conventional TMD, a novel possibility to control vibration relies on using another existing rail as a lateral distributed resonator (LDR). Although the effectiveness of LDR is lower than that of localized resonators, the former represents a simple and promising way to control vibrations. Efficacy of the proposed control methods is finally verified by applying a random Gaussian white noise input. The study presented here is useful to understand the propagation and attenuation behavior of flexural waves and to develop efficient and novel vibration control strategies for track structures.
