Lintlha tsa boithuto tsa indasteri ea turbocharger

Ho ile ha hlahisoa li-vibrations tse lekantsoeng tsa rotor ea koloi ea turbocharger 'me ho hlalositsoe litlamorao tse etsahalang.Mefuta e ka sehloohong e thabisang ea tlhaho ea rotor/bearing system ke gyroscopic conical forward mode le gyroscopic translational forward mode, ka bobeli mekhoa e batlang e thata ea 'mele e nang le ho kobeha hanyenyane.Litekanyo li bonts'a hore sistimi e bonts'a maqhubu a mane a mantlha.Leqhubu la pele la mantlha ke ho sisinyeha ha synchronous (Synchronous) ka lebaka la ho se leka-lekane ha rotor.Lekhetlo la bobeli le busang le hlahisoa ke moholi oa oli / sephali sa lifilimi tsa mokelikeli o ka hare, tse hlasimollang mokhoa oa pele oa gyroscopic conical.Lekhetlo la boraro le ka sehloohong le boetse le bakoa ke ho phatloha ha oli / sephali sa lifilimi tse ka hare, tseo hona joale li thabisang mokhoa oa ho fetolela pele oa gyroscopic.Mokhahlelo oa bone o ka sehloohong o hlahisoa ke moholi oa oli / sephali oa lifilimi tsa mokelikeli o ka ntle, tse hlasimollang mokhoa oa pele oa gyroscopic conical.Li-superharmonics, li-subharmonics le li-frequencies tse kopantsoeng-tse entsoeng ke maqhubu a mane a maholo-li hlahisa maqhubu a mang, a ka bonoang ka makhetlo a mangata.Tšusumetso ea maemo a fapaneng a ts'ebetso ho li-vibrations tsa rotor e ile ea hlahlojoa.

Ka lebelo le pharaletseng la lebelo, matla a li-rotor tsa turbocharger ka har'a li-ring-ring tse phaphametseng ka ho feletseng li laoloa ke lintho tse etsahalang ka har'a mokelikeli o ka hare le oa ka ntle oa li-ring ring tse phaphametseng.Oli whirl/whip phenomena ke ho thothomela ha motho ka bouena, ho susumetsoang ke phallo ea mokelikeli lekhalong la ho beha.
