Nā palapala noiʻi o ka ʻoihana turbocharger
Ua hōʻike ʻia nā haʻalulu rotor o kahi rotor turbocharger automotive a wehewehe ʻia nā hopena ikaika. ʻO nā ʻano ʻano hauʻoli nui o ka ʻōnaehana rotor/bearing, ʻo ia ke ʻano conical conical i mua a me ke ʻano unuhi unuhi gyroscopic i mua, ʻelua ʻano ʻano kino ʻoʻoleʻa me ka piko liʻiliʻi. Hōʻike nā ana e hōʻike ana ka ʻōnaehana i ʻehā mau alapine nui. ʻO ke alapine nui mua ʻo ka synchronous vibration (Synchronous) ma muli o ke ʻano ʻole o ka rotor. Hoʻokumu ʻia ka alapine ʻelua e ka ʻaila whirl/whip o nā kiʻiʻoniʻoni wai i loko, kahi e hoʻoulu ai i ke ʻano conical gyroscopic i mua. ʻO ke kolu o ke alapine nui ke kumu ʻia e ka ʻaila whirl/whip o nā kiʻiʻoniʻoni i loko, i kēia manawa e hoʻohauʻoli nei i ke ʻano unuhi mua gyroscopic. Hoʻokumu ʻia ka alapine ʻehā e ka ʻaila whirl/whip o nā kiʻiʻoniʻoni wai o waho, e hoʻoulu ai i ke ʻano conical gyroscopic i mua. ʻO Superharmonics, subharmonics a me nā alapine hui-i hana ʻia e nā alapine nui ʻehā-hoʻohua i nā alapine ʻē aʻe, hiki ke ʻike ʻia i ka spectra frequency. Ua nānā ʻia ka mana o nā ʻano hana like ʻole i nā haʻalulu rotor.
Ma kahi ākea ākea, ʻo ka dynamics o nā rotors turbocharger i loko o nā bearings apo holo piha e hoʻomalu ʻia e ka ʻaila whirl / whip phenomena e kū nei i nā kiʻiʻoniʻoni o loko a me waho o nā bearings apo. ʻO ka ʻaila whirl/whip phenomena he mau haʻalulu hoʻohiwahiwa iā ia iho, i hoʻoulu ʻia e ka kahe o ka wai i loko o ka ʻāwaha bearing.
