Zolemba zamaphunziro amakampani a turbocharger

Kugwedezeka kwa ma rotor kwa rotor yamagalimoto yama turbocharger kudawonetsedwa ndipo zomwe zikuchitika zidafotokozedwa. Mitundu yayikulu yosangalatsa ya kachitidwe ka rotor/bearing system ndi gyroscopic conical forward mode ndi gyroscopic translational front mode, onse pafupifupi olimba thupi modekha ndi kupindika pang'ono. Miyezo ikuwonetsa kuti dongosololi likuwonetsa ma frequency anayi akuluakulu. Kuthamanga kwakukulu koyamba ndi kugwedezeka kwa synchronous (Synchronous) chifukwa cha kusalinganika kwa rotor. Wachiwiri wolamulira pafupipafupi amapangidwa ndi kamvuluvulu wamafuta / chikwapu cha mafilimu amadzimadzi amkati, omwe amasangalatsa mawonekedwe a gyroscopic conical forward. Kuthamanga kwachitatu kwakukulu kumayambitsidwanso ndi kamvuluvulu wamafuta / chikwapu cha mafilimu amkati, omwe tsopano amasangalala ndi gyroscopic translational forward mode. Mafupipafupi achinayi amapangidwa ndi kamvuluvulu wamafuta / chikwapu cha mafilimu amadzimadzi akunja, omwe amasangalatsa mawonekedwe a gyroscopic conical forward. Superharmonics, subharmonics ndi ma frequency ophatikizika-opangidwa ndi ma frequency anayi akuluakulu-amapanga ma frequency ena, omwe amatha kuwoneka mu mawonekedwe afupipafupi. Chikoka cha machitidwe osiyanasiyana opangira pa ma rotor vibrations adawunikidwa.

Mu liwiro lalikulu, mphamvu za turbocharger rotor muzitsulo zoyandama zoyandama zimayendetsedwa ndi zochitika zamafuta / chikwapu zomwe zimachitika m'mafilimu amadzimadzi amkati ndi akunja a mayendedwe a mphete zoyandama. Kugwedezeka kwamafuta / chikwapu ndi kunjenjemera kodzisangalatsa, komwe kumabwera chifukwa cha kutuluka kwamadzi mumpata wonyamula.
