Abstract
V prispevku je predstavljena analiza zvoka v železniskih vozilih. S tehničnim razvojem železniških vozil se povečuje tudi hitrost vlakov, zato se povečuje tudi jakost zvoka, ki pri tem nastane. Hrup je ena izmed škodljivih posledic transporta. Ker je v bivalnih okoljih raven zvoka eden izmed pomembnejših pokazateljev bivalnega ugodja, se povečuje pozornost namenjena raziskavam poteka zvoka. V prispevku so predstavljeni zvok, ki ga povzročajo prevozna sredstva, njegovo širjenje in njegovo spreminjanje v notranjih prostorih vozil ter različni viri zvoka pri železniskem transportu. Obravnavani so tehnični, organizacijski in administrativni ukrepi za zmanjšanje nastanka zvoka. Prav tako pa so prikazani tudi škodljivi vplivi zvoka na zdravje ljudi.Za raziskavo smo izbrali dve vrsti ruskih lokomotiv M62 in TEP60. Z uporabo programske opreme ANSYS/Multiphysic smo simulirali zvok motorjev z različno močjo. Rezultate preračunov zvoka smo nato primerjali z dovoljenimi vrednostmi.

Title:Numerical modelling of the internal sound in railway rolling stock
Abstract:
The paper presents an analysis of the sound in railway rolling stock. The speeds of trains tend to increase as railway rolling stock improves technically and becomes more sophisticated: however, the sound generated is intensified too. Noise is one of the harmful consequences of transport. As thesound level in domestic surroundings is one of the most important human-comfort indices, increasing attention is being devoted to an investigation of sound processes. The sound generated by transport vehicles, its distribution, and its variation in internal transport-vehicle spaces, and various sound sources in railway transport are considered in the paper. Engineering, organizational and administrative sound-reducing measures are discussed. The harmful effects of sound on human health are discussed as well. Two types of Russian production locomotives - the M62 and the TEP60 - were selected for this research. Using ANSYS/Multiphysic software the acousticsound of the different power units in the engine sector was simulated.The results of the sound calculations were compared with the acceptable levels.
