Sažetak Gradovi Hamburg, Rennes, Lausanne i Liverpool su europski gradovi sa različitim sustavom podzemne željeznice čiji razvoj odgovara ekonomskoj situaciji gradskih središta. Trenutno stanje pojedinih podzemno željeznićkih sustava i njihova primjenjena tehnologija uvelike odražava stanje razvoja javnog gradskog prijevoza i mreže javnog gradskog prometa. Svaki od prijevoznika u podzemnim željeznicama u tim gradovima ima različiti tehnički pristup obavljanja javnog gradskog prijevoza te korištenjem optimalnim brojem motornih prijevoznih jedinica osigurava zadovoljenje potreba javnog gradskog i metropolitanskog područja grada. Kroz usporedbu tehničkih podataka pojedinih podzemnih željeznica može se uvidjeti i zaključiti koji od sustava podzemnih željeznica je veći i koje oblike tehničkih rješenja koristi. Ključne riječi: Hamburg, Rennes, Lausanne, Liverpool, podzemna željeznica, javni gradski prijevoz, linija, tip vlaka, tvrtka, prihod, cijena. Summary Cities Hamburg, Rennes, Lausanne and Liverpool are european cities with different metro system by wich development reflects economic situation of city areas. -
Interior Noise Reduction Approach for Monorail System
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by UTHM Institutional Repository INTERIOR NOISE REDUCTION APPROACH FOR MONORAIL SYSTEM DJAMAL HISSEIN DIDANE A thesis submitted in fulfillment of the requirement for the award of the Degree of Master of Science in Railway Engineering Center For Graduate Studies Universiti Tun Hussein Onn Malaysia JANUARY 2014 v ABSTRACT This study presents an overview on the possibilities of interior noise reduction for monorail system using passive means. Nine samples out of three materials were subjected for noise test and the performance of each sample was observed. It is found that all of these samples have proved to reduce a significant amount noise at low and high frequencies even though the amount reduced differ from one sample to another. It is also been noticed that this reductions were denominated by means of absorption for some samples such as those from rubber material, and it was dominated by means of reflection for some others such as those from aluminum composite and paper composite. Moreover, from these different acoustic properties of each material, the whereabouts to install every material is different as well. It was suggested that, the rubber material should be installed on the upper floor of the monorail while, the paper composite should be installed under floor, and the aluminum composite should be installed at the outer parts from the monorail such as the apron door, ceiling, etc. However, despite their promising potential to reduce noise, there were few uncertainties with some samples at certain frequency, for example samples from aluminum composite could not reduce noise at 1250 Hz which denotes that it is not a good practice to use this material at that frequency. -

Printed by Chalmers Reproservice Göteborg, Sweden, 2010 ii Applicable Directivity Description of Railway Noise Sources XUETAO ZHANG Department of Civil and Environmental Engineering Division of Applied Acoustics Chalmers University of Technology Abstract For a sound source, directivity is an important parameter to specify. This parameter also reflects the physical feature of the sound generation mechanism. For example, turbulence sound is of quadrupole directivity while fluid-structure interaction often produces a sound of dipole characteristic. Therefore, to reach a proper directivity description is in fact a process of understanding the sound source in a better way. However, in practice, this is often not a simple procedure. As for railway noise engineering, several noise types of different directivity characters are often mixed together, such as wheel and rail radiation, engine and cooling fan noise, scattered fluid sound around bogies and turbulent boundary layer noise along train side surfaces. -
