“…Thus it can be used: -to determine dynamic properties of tracks for typical noise measurements (for ISO 3095 [3]), i.e. to determine track suitability for the conduct of typical measurements, -as dynamic parameter in the separation of noise sources (vehicle and track) [24], -to determine indirect roughness of rail vehicle wheels [24], -as parameter for evaluation of various vibration attenuation systems [21,25].…”

The rail-track vibration damping level, as one of key properties for determining proportion of rail track influence in the total rail traffic noise and vibration levels, is estimated in the paper. A detailed overview of research conducted so far on dynamic properties of rail tracks is given, and the methods presented are compared on two test sections. The data processing method, various accelerometer positons, and various types of modal hammers as excitation sources, are also considered in the analysis of measurement results. The results obtained by various analyses are compared to each other so as to increase accuracy in the determination of the vibration damping level. Mjerenje stupnja prigušenja vibracija na klasičnim kolosiječnim konstrukcijama U radu se ocjenjuje stupanj prigušenja vibracija na kolosijecima, jednog od ključnih svojstava pri određivanju utjecaja kolosijeka u ukupnim razinama buke i vibracija od prometovanja tračničkih vozila. Prikazan je i detaljan pregled znanstvenih istraživanja na temu dinamičkih svojstava kolosijeka, a navedene metode uspoređene su na dvije ispitne lokacije. Nadalje, u analizi rezultata mjerenja razmatra se metoda obrade podataka, različite pozicije akcelerometara i različiti tipovi modalnih čekića kao izvora pobude. Rezultati dobiveni različitim analizama međusobno su uspoređeni u svrhu što preciznijeg određivanja stupnja prigušenja vibracija.

“…In the case of a finite length beam, forced at distance L1 from one end and L2 from the other, the forced response can be found from the four waves in equation (8) (11) The wave amplitudes are found by applying continuity at the forcing point as before as well as free boundary conditions at the ends. The ratio between the total decay rate, obtained by applying eq.…”

“…Particularly important is the track decay rate, the rate of attenuation of vibration along the rail, which governs the sound radiated by the rail [6,7]. In order to separate the wheel and track components, either advanced experimental techniques [8] or theoretical models [1,2] are required.…”
