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.
N'ime oke ọsọ ọsọ, ike nke turbocharger rotors na mgbanaka mgbanaka zuru oke na-achịkwa mmanụ whirl / phenomena na-eme na ihe nkiri dị n'ime na nke dị n'èzí nke mgbanaka na-ese n'elu mmiri. Mmetụta mmanụ whirl/ụrịa bụ ịma jijiji nke na-akpali onwe ya, na-ebute site na mmiri na-asọ na oghere ibu.
