Ndetu ọmụmụ nke ụlọ ọrụ turbocharger
Atụtara ịma jijiji rotor nke rotor ụgbọ ala turbocharger ma kọwaa mmetụta dị ike na-eme.Ụdị ụdịdị dị n'okike bụ isi nke rotor/ bearing mode bụ gyroscopic conical forward mode na gyroscopic ntụgharị ntụgharị ihu, ma ụdị ahụ ahụ siri ike na-eji ntakịrị agbagọ.Ntụle na-egosi na sistemụ na-egosipụta ugboro anọ bụ isi.Ugboro izizi bụ ịma jijiji mmekọrịta (synchronous) n'ihi ahaghị nhata rotor.Nke abụọ na-achị ugboro na-eme site mmanụ whirl / ụtarị nke n'ime mmiri ihe nkiri, nke na-akpali gyroscopic conical n'ihu mode.Nke atọ bụ isi ugboro na-ebutekwa site na mmanụ whirl/ụrị nke ihe nkiri dị n'ime, nke na-akpali ugbu a ụdị ntụgharị ntụgharị gyroscopic.Nke anọ bụ isi ugboro na-eme site na mmanụ whirl / ụtarị nke mpụta mmiri ihe nkiri, nke na-akpali gyroscopic conical n'ihu mode.Superharmonics, subharmonics na nchikota frequency — kere anọ bụ isi ugboro — na-emepụta ugboro ndị ọzọ, nke a pụrụ ịhụ na ugboro spectra.A na-enyocha mmetụta nke ọnọdụ ọrụ dị iche iche na vibrations rotor.
