Tushen hayaniyar girgiza a cikin injunan maganadisu na dindindin

Girgizarinjinan maganadisu na dindindingalibi yana fitowa ne daga fannoni uku: hayaniyar iska, girgizar injiniya, da girgizar lantarki. Hayaniyar iska tana faruwa ne sakamakon canje-canje cikin sauri a matsin lamba a cikin motar da gogayya tsakanin iskar gas da tsarin motar. Girgizar injina tana faruwa ne sakamakon nakasar roba ta lokaci-lokaci na bearings, lahani na geometric, da rashin daidaiton shaft na rotor. Girgizar lantarki tana faruwa ne ta hanyar motsin lantarki, kuma filin maganadisu na gaɓar iska yana aiki akan tsakiyar stator, yana haifar da nakasar radial na stator, wanda ake watsawa zuwa akwatin motar kuma yana haskaka hayaniya. Kodayake ɓangaren tangent na filin maganadisu na gaɓar iska ƙarami ne, yana iya haifar da girgizar juyi da girgizar mota. A cikin turawa nainjinan maganadisu na dindindin, motsin lantarki shine babban tushen girgiza.

A matakin farko na ƙirainjinan maganadisu na dindindin, ta hanyar kafa samfurin amsawar girgiza, nazarin halayen motsin lantarki da halayen motsi na tsarin, annabta da kimanta matakin hayaniyar girgiza, da kuma inganta ƙirar girgiza, ana iya rage hayaniyar girgiza, ana iya inganta aikin motar, kuma ana iya rage zagayowar ci gaba.

Za a iya taƙaita ci gaban binciken da ake samu a yanzu zuwa fannoni uku:

1. Bincike kan motsin lantarki: Jin motsin lantarki shine babban dalilin girgiza, kuma bincike ya kasance yana gudana tsawon shekaru da yawa. Binciken farko ya haɗa da ƙididdige rarrabawar ƙarfin lantarki a cikin injina da kuma samar da dabarun nazari don ƙarfin radial. A cikin 'yan shekarun nan, an yi amfani da hanyoyin kwaikwayon abubuwa masu iyaka da nazarin lambobi sosai, kuma masana na cikin gida da na ƙasashen waje sun yi nazarin tasirin tsarin ramuka daban-daban na pole akan ƙarfin cogging na injunan magnet synchronous na dindindin.

2. Bincike kan halayen tsarin tsarin: Halayen tsarin tsarin suna da alaƙa da amsawar girgizarsa, musamman lokacin da mitar motsawa ta kusa da mitar halitta ta tsarin, za a sami sautin sauti. Masana na cikin gida da na ƙasashen waje sun yi nazarin halayen tsarin tsarin stator na mota ta hanyar gwaje-gwaje da kwaikwayo, gami da abubuwan da ke shafar mitoci na tsarin kamar kayan aiki, modulus na roba, da sigogin tsarin.

3. Bincike kan Amsar Girgiza a ƙarƙashin Ƙarfin Wutar Lantarki: Amsar girgizar injin yana faruwa ne sakamakon ƙarfin lantarki da ke aiki akan haƙoran stator. Masu bincike sun yi nazarin rarrabawar ƙarfin lantarki na spatiotemporal, ƙarfin lantarki da aka ɗora akan tsarin stator na motar, kuma sun sami lissafin lambobi da sakamakon gwaji na amsawar girgizar. Masu binciken sun kuma bincika tasirin ƙarfin damping na kayan harsashi akan amsawar girgizar.
