“…Although a large number of literature reported its effectiveness, it remains controversial for underground railways due to the interactions with the supporting foundations at lower frequencies. [4][5][6][7] The analysis of the isolation performance using simple mass-spring models reveals that vibrations can be isolated only for the frequency above √ 2 times the natural frequency of the system. Therefore, the FST is undesirable in attenuating vibrations at the low frequency below 20 Hz, due to the fact that the first natural frequency of the FST is generally around 13 Hz.…”

This study aims to effectively and robustly suppress the low-frequency vibrations of floating slab tracks (FSTs) using dynamic vibration absorbers (DVAs). First, the optimal locations where the DVAs are attached are determined by modal analysis with a finite element model of the FST. Further, by identifying the equivalent mass of the concerned modes, the optimal stiffness and damping coefficient of each DVA are obtained to minimise the resonant vibration amplitudes based on fixed-point theory. Finally, a three-dimensional coupled dynamic model of a metro vehicle and the FST with the DVAs is developed based on the nonlinear Hertzian contact theory and the modified Kalker linear creep theory. The track irregularities are included and generated by means of a time-frequency transformation technique. The effect of the DVAs on the vibration absorption of the FST subjected to the vehicle dynamic loads is evaluated with the help of the insertion loss in one-third octave frequency bands. The sensitivities of the mass ratio of DVAs and the damping ratio of steel-springs under the floating slab are discussed as well, which provided engineers with the DVA's adjustable room for vibration mitigation. The numerical results show that the proposed DVAs could effectively suppress low-frequency vibrations of the FST when tuned correctly and attached properly. The insertion loss due to the attachment of DVAs increases as the mass ratio increases, whereas it decreases with the increase in the damping ratio of steel-springs.

Steel-spring floating-slab (SSFS) has been widely used in track structure because of its effective vibration isolation. The energy transferred to the foundation is significantly reduced. Usually, the frequencies are low in the course of analyzing the vibration of a floating slab. When considering the vibration isolation effect of SSFS, the mass of spiral spring and its detailed structure in the supports is usually ignored. This assumption will cause errors in the high frequency vibration characteristics. In fact, there is certain mass in the supports of floating slab. In addition, when the diameter of spring is equal to integer times of a halfelastic wave in it, the wave effect can be produced in the supports. At this time, the standing wave effect in the spiral springs should not be ignored. Based on the linear assumption and using the four-end parameter analysis method, we get the range of frequency that is caused by the wave effect. Three groups of noise in a carriage of an actual running vehicle are measured. In addition, it is explained why the noise is higher when the vehicle is running over an SSFS zone, compared with the common track. Some suggestions are put forward that will reduce the low frequency noise in the urban transit carriage.

“…Results of studies conducted in different countries published in (e.g. [1][2][3]) are not always comparable because of differences in the structures of trains and surface rail, the differences in soil conditions, and finally due to local differences of the buildings' construction receiving the vibration. Therefore, also in Poland, after purchasing the Pendolino trains, it was decided that test drives need to be performed within the test framework of vibration generated by the passing train (Fig.…”

The objective of the paper was to conduct dynamic measurements of free-field vibrations in three profiles and establish decay relations of propagating vibrations. The sources of vibrations were passages of the Pendolino train with dedicated speeds from 40 to 293 km/h. In each profile, soil properties tests were carried out. Based on the data for a few selected speeds of the Pendolino train' s passages, the Vibration Reduction Coefficients (VRC) were determined at selected points. The paper is also focused on the analysis of vibrations of the selected one-storey masonry residential building located in the vicinity of one of the profiles and their evaluation of the harmfulness on the building structure using standard scales of dynamic influence.Keywords: free-field vibrations, dynamic investigation, speed of passage of a train, building vibrations, harmfulness of vibrations Streszczenie W pracy przedstawiono wyniki analiz pomiarów drgań gruntu w trzech profilach oraz podano zależności tłumienia propagujących się w gruncie drgań, których źródłem były przejazdy pociągu Pendolino z dedykowanymi prędkościami 40-293 km/h. W każdym profilu określono właściwości gruntu. Na podstawie danych pomiarowych wyznaczono współczynniki redukcji drgań w wybranych punktach. W pracy przedstawiono także wyniki analiz pomierzonych drgań murowego, jednopiętrowego budynku mieszkalnego zlokalizowanego w sąsiedztwie jednego z profili pomiarowych prowadzonych pod kątem oceny ich szkodliwości na konstrukcję budynku. W ocenach wykorzystano normowe Skale Wpływów Dynamicznych.Słowa kluczowe: wstrząsy górnicze, przekazywanie drgań z gruntu na fundament budynku, transmisja spektrów odpowiedzi 86
