20.500.12556/RUL-94497 Priprava merilne škatle za ločeno merjenje hrupa sesalne enote Preparation of the measuring box for seperate measuring of noise of vacuum sucking unit V tem delu je predstavljeno merjenje hrupa sesalne enote na strani, kjer zrak v enoto vstopa ter na strani, kjer zrak iz nje izstopa, z namenom, da se potrdi kako naj bi bila sesalna enota pozicionirana znotraj sesalnika prahu, da bi bil hrup le tega čim nižji. Meritev je bila izvedena znotraj merilne škatle, ki je bila skonstruirana tako, da je možno ločeno pomeriti prispevek hrupa elektromotorja (prevladuje elektromagnetni hrup) in prispevek hrupa turbokolesa, na katerem prevladuje aerodinamični vir hrupa. Ugotovljeno je bilo, da je raven zvočnega tlaka odvisna od lege opazovalne točke. This work presents measurements of noise of vacuum sucking unit, which were made on both sides of vacuum sucking unit - at first at side, where air is entering into the unit, later at side, where air is leaving the unit. Intention of measurements is display of the most favourable position of the vacuum sucking unit inside of the vacuum cleaner unit considering wish of reducing noise of the vacuum cleaner unit. Measurements were made inside of measuring box, which was engineered in a way that the noise of electric motor and noise of centrifugal wheel can be tried for size separately. Final finding is, that level of sound pressure depends upon point of observation. sesalna enota elektromotor aerodinamični hrup strukturalni hrup zvok nihanja vacuum suction unit electrical motor aerodynamical noise structural noise sound vibrations true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-01 07:15:06 2017-09-01 07:15:12 2023-10-27 12:24:11 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 199217 381.pdf 381.pdf 1 7E1BE047B1EC536C86301B2F0CB9FCBE 020cc9b1199690dd1060c811b15d7a93b0c1997f942ad6c7249ac1e20e93ba4f 888b4f6d-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/f11cb68f-42c0-4cd6-a04f-536b9324f59b https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102722 384.pdf 384.pdf 1 5C7333367491F1884B67F729947AE5B6 5a99e6a34b35f535204b2b06a757342b3b6e4d0dec3000a968b460076279c6c9 88b40bd6-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/83bb3d32-ca8a-47af-8939-fed8f9b2a502 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102725 382.pdf 382.pdf 1 7167CEF4AF0319E0D8EB3694640435EA 59406cd10ecd1e25b41ff58553bd93fe2039acbd8ebe10e6423c658ca745fdc8 8898feda-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/4bacb58a-8ea8-435d-9d97-9a026ac0c0ca https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102723 385.pdf 385.pdf 1 A57AE0DA45F9294151C9F23B75010242 27f8b9acd023051494939f294c5307c2a2670a5bed63a1e6112bda7be7eb9bb6 88c2558c-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/f16d20bf-9ea1-4da0-b871-f5009fe2153e https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102726 383.pdf 383.pdf 1 6B88B8481E465E7854AB3A862A146A6B ef5ad3797dcd544b1f0f89733e4d0f9dbf5d1f8b686ce0885353908d739160ec 88a5b8e3-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/6a65624f-3cdd-42c1-bc02-651407653668 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102724 Fakulteta za strojništvo 0 0 0
