1. Design av reaktiv ljuddämpare till pneumatisk mutterdragare
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Detta projekt hade som syfte att undersöka möjligheten att konstruera en reaktiv ljuddämpare till Atlas Copco:s pneumatiska mutterdragare EP15-PTX250. Projektet bestod av ljudmätningar, databehandling, simuleringar och prototypkonstruktion. Syftet var att framställa en 3D-utskriven reaktiv prototyp. LÄS MER
2. DEVELOPMENT OF ACOUSTIC MODELS FOR HIGH FREQUENCY RESONATORS FOR TURBOCHARGED IC-ENGINES
Master-uppsats, KTH/MWL Marcus Wallenberg LaboratorietSammanfattning : Automotive turbo compressors generate high frequency noise in the air intake system. This sound generation is of importance for the perceived sound quality of luxury cars and may need to be controlled by the use of silencers. The silencers usually contain resonators with slits, perforates and cavities. LÄS MER
3. Analysis and mathematical modelling of industrial truck silencers
Magister-uppsats, Matematiska och systemtekniska institutionenSammanfattning : The currently low requirements on sound emissions for industrial trucks are expected to be raised in the near future. The company Kalmar Industries AB, which develop, produce and market industrial trucks, want to improve their truck silencers as a precaution to the future harder restrictions and also to improve their competitiveness.
