- Ayini amayunithi wokubala yenani lokudlidliza kwemoto? Ungawaqonda kanjani la mayunithi?
Amayunithi okulinganisa asetshenziswa kakhulu wenani lokudlidliza kwezimoto inani elisebenzayo ngesivinini (okubhekiselwa kulo njengejubane), inani le-amplitude yokudlidliza (okubhekiselwa kulo njengo-amplitude, ihlukaniswe yaba i-amplitude eyodwa kanye ne-double amplitude) kanye nokusheshisa ukudlidliza. Eyokuqala isetshenziswa kakhulu.
"Ivelu esebenzayo yesivinini" ingaqondwa kalula njengebanga elinyakaziswa into edlidlizayo (engathathwa njengephuzu) ngesikhathi seyunithi. Ibanga elingu-W okuyibanga lapho okokusebenza okudlikizayo elijikayo kuye emuva naphambili endaweni eyodwa futhi ayihambi iye kwezinye izindawo. Ngakho-ke, lokho okubizwa ngokuthi "ibanga elinyakazayo" kungaba indlela yokuchaza kuphela, ngakho-ke amagama athi "isebenza kahle" noma "elilinganayo" asetshenziselwa ukuqhubeka nokulichaza. Kungacatshangwa ukuthi inani lejubane lokudlidliza lihlobene nebanga le-amplitude yokudlidliza (ibanga ukusuka endaweni emaphakathi) yephoyinti lokudlidliza. Ngaphezu kwalokho, ihlobene nemvamisa yokudlidliza (inani lokushwibeka emuva naphambili ngesikhathi seyunithi) futhi ayalingana; ngokuvamile mm/s isetshenziswa njengeyunithi.
Iphuzu lokudlidliza liyizinhlayiyana ezijikela emuva naphambili ngezinhlangothi ezimbili. Lapho ushwiba, ibanga eliphakeme ukusuka endaweni ephakathi libizwa ngokuthi i-amplitude. Ibanga eliphakeme ohlangothini olulodwa libizwa ngokuthi i-amplitude eyodwa, futhi ibanga eliphakathi kwamaphoyinti akude kakhulu ezinhlangothini ezimbili libizwa ngokuthi i-amplitude ephindwe kabili - ngokuvamile ku-mm noma μm.
Ukusheshisa ukudlidliza ukukhuphuka kwesivinini ngesikhathi seyunithi engu-M, ngokuvamile ku-m/s2.
- Imaphi amanani amabili wevelu esebenzayo yesivinini kanye ne-amplitude yenani lokudlidliza okungcono? Ingabe bukhona ubudlelwano bokuguqulwa phakathi kwabo?
Njengoba kushiwo ngenhla, inani le-amplitude libonisa kuphela usayizi we-swing amplitude, kuyilapho inani elisebenzayo lejubane libonisa kokubili ubukhulu be-amplitude kanye nesivinini sokushwibeka. Izinga lomonakalo odalwe ukudlidliza kunjini ngokwayo kanye nemishini ehlobene ihlobene ne-amplitude nemvamisa (isivinini sokushwiba). Ngakho-ke, kuwumgomo omkhulu futhi kubaluleke kakhulu ukusebenzisa isivinini sokudlidliza ukuhlola usayizi wevelu yokudlidliza yemoto. Lesi futhi isizathu sokuthi kungani inani elisebenza ngempumelelo isivinini ngokuvamile lisetshenziswa njengevelu yokulinganisa ukudlidliza kumazinga afanele wamazwe ngamazwe nawasekhaya.
Ngenxa yokuthi izimo zokukhiqiza amanani amabili ejubane ne-amplitude azifani ncamashi, isivinini sinefrequency eyodwa yokudlidliza kune-amplitude. Okokugijima induction motor,imvamisa yokudlidliza ayiyona eyodwa, futhi ngezinye izikhathi iyinkimbinkimbi kakhulu, ngakho kokubili amafrikhwensi aphezulu akhiqizwa ama-electo-magnetics kanye namaza aphakathi nendawo naphansi akhiqizwa imishini.
Ngakho-ke, abukho ubuhlobo obunqunyiwe bokuguqulwa phakathi kokubili, kodwa ngokuvamile, lapho i-amplitude inkulu, isivinini sokudlidliza sizokhuphuka ngokufanele.
- Izizathu ezingenzeka zokudlidliza okukhulu kwenjini:
(1) Ama-bearings athengiwe awekhwalithi embi futhi awahlangabezani nezindinganiso zekhwalithi. Umhlangano awenziwa ngokuvumelana nezidingo zenqubo, okubangela ukuguquguquka ngenxa yomthelela. Ukubekezelelana kwegumbi lokuthwala lesembozo sokuphela kwemoto akunangqondo, kuqine kakhulu noma kuxege kakhulu. Ngalesi sikhathi, indlela elula iwukusebenzisa isando ukuze ungqongqoze ngobumnene eksisi ukuze ubone ukuthi akukho yini ukuthuthukiswa.
(2) Ngenxa yokuma okuphezulu kwekhava yokuthwala noma isiphethu segagasi siqine kakhulu, ama-bearings emikhawulweni yomibili abambekile. Ngalesi sikhathi, ukudlidliza kwe-i-asynchronous motor yesigaba ezintathukuvame ukuphakama, futhi umsindo "obhuzayo" uvame ukukhishwa.
(3) Ibhalansi eguquguqukayo ye-rotor ayilungile, futhi ukunemba akwanele.
(4) Igebe lomoya phakathi kwe-stator ne-rotor alilingani, futhi kukhona isenzakalo sasendaweni esishanelayo.
(5) I-rotor iphukile, futhi umthamo wamanje uzoshwibeka ngesikhathi esithile.
(6) Imotor kagesiunyawo alulingani, noma alufakwanga lugxile ezintweni zokulayisha.
