Amanqaku ophononongo kwishishini le-turbocharger
Umlinganiselo wokungcangcazela kwerotor ye-automotive turbocharger yaboniswa kwaye iziphumo eziguqukayo ezenzekayo zichaziwe. Ezona ndlela ziphambili zovuyo zendalo zerotor/inkqubo yokuthwala yimowudi ye-gyroscopic conical phambili kunye nemowudi yokuguqulela phambili ye-gyroscopic, zombini iimowudi zomzimba eziphantse zibe ngqongqo ngokugoba okuncinci. Imilinganiselo ibonisa ukuba inkqubo ibonisa iifrikhwensi ezine eziphambili. I-frequency yokuqala ephambili yi-synchronous vibration (Synchronous) ngenxa yokungalingani kwe-rotor. I-frequency yesibini elawulayo iveliswa yi-oil whirl / i-whip yeefilimu zangaphakathi zolwelo, ezivuyisa imowudi ye-gyroscopic conical phambili. I-frequency yesithathu engundoqo nayo ibangelwa yi-oil whirl / i-whip yeefilimu zangaphakathi, ezivuyisa ngoku imowudi yokuguqulela phambili ye-gyroscopic. I-frequency yesine engundoqo iveliswa yi-oil whirl / i-whip yeefilimu zangaphandle zolwelo, ezivuyisa imowudi ye-conical phambili ye-gyroscopic. I-Superharmonics, i-subharmonics kunye ne-frequency edibeneyo-eyenziwe ngama-frequencies amane aphambili-ivelisa ezinye iifrikhwensi, ezinokubonwa kwi-frequency spectra. Impembelelo yeemeko ezahlukeneyo zokusebenza kwi-rotor vibrations ihlolwe.
Kuluhlu olubanzi lwesantya, i-dynamics ye-turbocharger rotors kwiibheringi ezijikelezayo ezigcweleyo zilawulwa yi-oil whirl / i-whip phenomena eyenzeka kwiifilimu zangaphakathi kunye nangaphandle zolwelo zeebheringi ezidadayo. I-oil whirl / i-whip phenomena zi-vibrations ezizithandayo, ezibangelwa ukuhamba kwamanzi kwi-gap yokuthwala.
