Abstract
U ovom radu napravljen je pregled metoda koje se bave analizom vibracija u željezničkom vozilu i objašnjeno je na koji način se pomoću tih metoda može ocjenjivati udobnost vožnje. Metode za analizu vibracija koje su proučavane u okviru ovog rada su Sperling metoda za određivanje mirnoće hoda i udobnosti vožnje i metoda prema normi HRN EN 12299 za određivanje udobnosti vožnje u željezničkim vozilima. Zatim je prikazana dionica na tramvajskoj mreži Zagrebačkog električnog tramvaja i opisano je na koji su način izmjerene vibracije u tramvajskom vozilu. Nakon što su detaljnije opisane metode pomoću kojih se ocjenjuje udobnost vožnje u željezničkom vozilu, uspoređene su dvije navedene metode. Analiziran je način obrade podataka, interpretacija podataka u odnosu na zadane granične vrijednosti, primjenjivost metoda u tramvajskom prometu kojeg odlikuju male brzine prometovanja i zahtjevna konfiguracija trase, te njihove prednosti, nedostaci, sličnosti i razlike. U posljednjem poglavlju izvršena je frekvencijska analiza pomoću koje se mogu detektirati određene pojave i nepravilnosti na kolosijeku na temelju prikupljenih vibracija. Uočen je veliki potencijal za detekciju i evaluaciju pozicije i stanja zavarenih spojeva na temelju razina zabilježenih vibracija prilikom prolaska tramvajskog vozila.
Abstract (english)
This master thesis gives an overview of methods for analysis of vibrations in railway vehicles. It gives an insight into procedures for calculating ride comfort in rail vehicles. Methods used for vibration analysis in scope of this thesis are Sperling index calculation for determining ride quality and ride comfort and HRN EN 12299 method for determining ride comfort in railway vehicles. further the test section on Zagreb tram network is presented where vibrations have been recorded using an instrumented tram vehicle. Detailed description of procedure for analysis of ride comfort using both methods is given, and methods have been compared to each other. Comparison included a method of data processing, data interpretation in respect to prescribed limits, ability of application of methods on tramway networks where different operation conditions such as low speed, challenging track alignment, as well as other advantages and shortcomings, similarities and differences. last chapter gives the frequency analysis used for detection of certain flaws and events on tramway track based on vibration measurements. The described method has potential for detection and evaluation of weld position and condition based only on bogie vibration measurements.
