Tushen hayaniyar Jijjiga a cikin injunan maganadisu na dindindin

Jijjiga nana dindindin maganadisu na aiki tareyafi zuwa daga bangarori uku: aerodynamic amo, inji vibration, da electromagnetic vibration.Aerodynamic amo yana faruwa ne ta hanyar saurin sauye-sauye a matsa lamba na iska a cikin motar da gogayya tsakanin iskar gas da tsarin motar.Jijjiga injina yana faruwa ne ta hanyar nakasar naƙasa na lokaci-lokaci na bearings, lahani na geometric, da rashin daidaituwar ramin rotor.Jijjifin lantarki yana faruwa ne ta hanyar motsa jiki na lantarki, kuma filin maganadisu na iska yana aiki a kan ma'aunin stator, yana haifar da nakasar radial na stator, wanda ake watsawa zuwa cakin mota kuma yana haskaka hayaniya.Ko da yake ɓangaren tangential na filin maganadisu na iska yana da ƙanƙanta, yana iya haifar da jujjuyawar juzu'i da motsin motsi.A cikin motsa jiki nana dindindin maganadisu na aiki tare, electromagnetic excitation shine babban tushen jijjiga.

A farkon zane mataki nana dindindin maganadisu na aiki tare, Ta hanyar kafa samfurin amsawar girgizawa, nazarin kaddarorin abubuwan haɓakawa na electromagnetic da haɓakar halayen tsarin, tsinkaya da kimanta matakin ƙarar ƙararrawa, da haɓaka ƙirar ƙira don rawar jiki, ana iya rage ƙarar ƙararrawa, ana iya inganta aikin motsa jiki, kuma za a iya taqaitaccen zagayowar ci gaba.

Ana iya taƙaita ci gaban bincike na yanzu zuwa sassa uku:

1.Bincike akan tashin hankali na lantarki: Tashin hankali na lantarki shine ainihin dalilin girgiza, kuma bincike yana gudana shekaru da yawa.Binciken farko ya haɗa da ƙididdige rarraba ƙarfin wutar lantarki a cikin injina da kuma samun ƙididdiga na ƙididdiga don sojojin radial.A cikin 'yan shekarun nan, an yi amfani da hanyoyin siminti na ƙayyadaddun ƙayyadaddun ƙayyadaddun abubuwa da ƙididdigar ƙididdiga, kuma masana cikin gida da na waje sun yi nazarin tasirin jeri daban-daban na ramin sandar sanda a kan jujjuyawar injin maganadisu na dindindin.

2. Bincike game da halaye na tsarin tsarin: Abubuwan halayen tsarin suna da alaƙa da alaƙa da amsawar girgiza, musamman lokacin da mitar motsawa ta kusa da mitar yanayi na tsarin, resonance zai faru.Masanan cikin gida da na waje sun yi nazarin halayen tsarin tsarin tsarin motar motsa jiki ta hanyar gwaje-gwaje da simulations, gami da abubuwan da ke shafar mitoci na modal kamar kayan aiki, modules na roba, da sigogin tsari.

3. Bincike akan Amsar Vibration a ƙarƙashin Excitation na Electromagnetic: Amsar girgizar motsin motar tana faruwa ne ta hanyar motsa jiki na lantarki da ke aiki akan haƙoran stator.Masu bincike sun yi nazarin rarraba sararin samaniya na ƙarfin lantarki, ɗora ƙarfin lantarki na lantarki akan tsarin stator, kuma sun sami ƙididdiga na lambobi da sakamakon gwaji na amsawar girgiza.Masu binciken kuma sun binciki tasirin damping coefficient na kayan harsashi akan amsawar girgiza.
