Abstract:V diplomskem delu je predstavljen razvoj izpušnega dušilnega sistema, ki je prilagojen karakteristikam eno-valjnega KTM 450 SX-F štiritaktnega motorja in zahtevam pravilnika kategorije Formula Student. Razvoj izpušnega dušilca je potekal v več fazah, ki so se pričele s posnetjem frekvenčne karakteristike nedušenega izpuha motorja na podlagi katere se je s pomočjo 1D simulacij linearne akustike določilo tri različne konfiguracije dušilcev. Na vseh treh konfiguracijah se je izvedla meritev transmisijske izgube hrupa na realnih dušilcih, s čimer se je preverila primerljivost simulacij z realnostjo. Izsledki primerjave so predstavljeni v zaključku naloge, kjer so podane tudi smernice za nadaljnje delo.

Title:Development of Exhaust Muffler for the Formula Student Race Car
Abstract:The aim of this thesis is to present the development of a bespoke exhaust muffler system which is tailored to characteristics of a single cylinder KTM 450 SX-F 4-stroke engine and requirements of Formula Student rules. The development was conducted in several phases starting with measurements of frequency characteristics of an unmuffled exhaust noise. Based upon those characteristics three different muffler configurations were developed with the help of 1D linear acoustics simulation software. Mufflers were measured for their transmission loss performances which were compared with simulated results. Findings of comparisons are presented at the end of this article and recommendations for more accurate simulation results are provided.
Keywords:exhaust muffler, Formula Student, noise spectral analysis, 1D-simulation of linear acoustics, measurements of noise transmission loss
