Kutsikirira kwenzvimbo uye kudhonza-kunze deformation: Iri rudzi rwe deformation rinowanzo onekwa sekukonzerwa nemagetsi emagetsi.Nekuda kwesimba rekudzoreredza rinogadzirwa neazvino munzira imwe chete, kana migumo miviri yekoiri yakamanikidzwa, iyi repulsion simba inosvina mapedhi ega ega, zvichiita kuti Zvikamu zvinodzvanywa uye zvikamu zvinodhonzwa.Rudzi urwu rwekuchinja kazhinji harukanganise waya yekutungamirira pasi pemamiriro ekuti zvipikiri zvekumanikidza kumativi ese ari maviri haafambiswe: rudzi urwu rwekuchinja kazhinji runoshandura chinhambwe (axial) pakati pemakeke, uye capacitance (pakati pemakeke) inoratidzwa. mune parallel inductance mune yakaenzana dunhu capacitance) shanduko.Nekutungamirira kusiri kudhonzwa, iyo yakakwira frequency chikamu cheiyo spectrum ichachinja zvishoma.Iyo coil yese haina kuomeswa, chikamu chete chedaro pakati pemakeke chinodhonzwa, uye mamwe madaro ari pakati pemakeke anomanikidzwa.Zvinogona kuonekwa kubva ku spectrogram kuti mamwe mapeji eresonant anoenda kune yakakwira frequency direction nekuderera kwepamusoro kukosha;nepo mamwe maresonant peaks anoenda kune yakaderera frequency kutungamira uye anoperekedzwa nekuwedzera kweiyo yepamusoro kukosha.Deformation nzvimbo uye dhigirii deformation inogona kufungidzirwa uye kuongororwa nekuenzanisa nzvimbo iyo resonance peak iri pachena yakashandurwa, (nhamba yepamusoro) uye kuchinja kwehuwandu hweresonance peak.Iyo yakakwira-frequency chikamu cheiyo spectrogram ichachinja apo kudzvanywa kwenzvimbo uye kudhonza-kunze deformation kunokanganisa kutungamira.Kana dhigirii rekumanikidza kwenzvimbo uye kudhonza-kunze deformation yakakura, mamwe maresonance anokwira mune yakaderera frequency uye yepakati frequency mabhendi anopindirana, mapikisi ega ega anonyangarika, uye amplitude yeimwe resonance peaks inowedzera.
Turn-to-turn short circuit: Kana metallic inter-turn short circuit ikaitika mucoil, iyo inductance yese yecoil ichadzikiswa zvakanyanya, uye kuvharika kwecoil kuchiratidzo kuchaderedzwa zvakanyanya.Inoenderana neiyo spectrogram, iyo resonant peak yeyakaderera frequency bhendi ichave pachena ichienda kune yakakwira frequency kutungamira, uye panguva imwe chete, nekuda kwekuderera kwechipingamupinyi, iyo frequency yekupindura curve ichaenda kune kutungamira kwekuderera kwekudzikira mumhepo. yakaderera frequency bhendi, ndiko kuti, iyo curve ichakwira kumusoro neinopfuura 2ddB;Mukuwedzera, mutsauko pakati pe resonance peaks uye mipata pa spectrum curve ichaderedzwa nekuda kwekuderera kweQ kukosha.Iwo ma spectral curves epakati uye akakwira frequency mabhendi anopindirana neaya eyakajairika coil.
Tambo dzecoil dzakaputsika: Kana tambo dzecoil dzatyoka, iyo yese inductance yecoil inowedzera zvishoma.Inoenderana neiyo spectrogram, iyo resonant peak ye low-frequency band ichafamba zvishoma kune yakaderera-frequency kutungamira, uye attenuation mune amplitude icharamba isingachinjiki;iyo spectral curves yepakati-frequency uye yakakwirira-frequency mabhendi inopindirana ne spectrogram yeyakajairika coil.
Metal yekunze muviri: Mune yakajairika coil, kana paine simbi yekunze muviri pakati pemakeke, kunyangwe iine mhedzisiro payakaderera frequency yakazara inductance, iyo capacitance pakati pemakeke inowedzera.Iyo resonance peak yeyakaderera frequency chikamu che spectrum curve ichaenda kune yakaderera frequency direction, uye amplitude yepakati uye yakakwirira frequency chikamu checurve ichawedzera.
Lead displacement: Kana iyo inotungamira ichibviswa, haina kukanganisa inductance, saka iyo yakaderera frequency bhendi ye spectrum curve inofanira kunge yakaputirwa zvachose, uye chete curve mu2ookHz ~ 5ookHz chikamu chinoshanduka, kunyanya maererano neattenuation amplitude.Kana waya yekutungamirira ichienda kugoko, chikamu chepamusoro che spectrum curve chinofamba chichienda kune kuwedzera kuderera, uye jira rinofamba richidzika;kana waya inotungamira ichiswedera pedyo nekoiri, iyo yakakwira frequency chikamu che spectrum curve inofamba munzira yekudzikira kudzikira, uye curve inokwira kumusoro.
Axial buckle: Axial twist ndeyokuti pasi pekuita kwesimba remagetsi, coil inosundirwa kunze kumativi ose maviri.Kana yadzvinyirirwa nemigumo miviri, inomanikidzwa kuremara kubva pakati.Kana gaka regungano remushanduri wepakutanga rakakura kana mabhureki anomanikidzwa kuchinjika, coil inomonyoroka kuita S chimiro munzira yeaxial;deformation iyi inongoshandura chikamu che capacitance pakati pemakeke uye chikamu che capacitance kusvika pasi nokuti migumo miviri haishanduki.Iyo inter-screen capacitance uye capacitance pasi inoderera, saka iyo resonant peak inoenda kune yakakwirira frequency pane spectrum curve, iyo resonant peak padhuze yakaderera frequency inodonha zvishoma, uye resonant peak frequency padhuze nepakati frequency ichasimuka. zvishoma, uye kuwanda kwe3ookHz ~ 5ookHz kuchawedzerwa zvishoma.Mitsara ye spectral inonyanya kuchengetedza maitiro ekutanga.
Amplitude (dhayamita) deformation yecoil: Pasi pekuita kwesimba remagetsi, iyo yemukati coil inowanzo bvumiranwa mukati.Nekuda kwekuganhurirwa kwekugara kwemukati, iyo coil inogona kukanganiswa munzira yeamplitude, uye mupendero wayo uchange uri zigzag.Iyi deformation ichaita kuti inductance ideredze zvishoma, iyo capacitance kusvika pasi zvakare inoshanduka zvishoma, saka iyo resonance peak mune yese frequency renji inofamba zvishoma kune yakakwirira frequency direction.Iyo amplitude deformation yekunze coil inonyanya kuwedzera kunze, uye iyo yakazara inductance ye deformation coil ichawedzera, asi chinhambwe pakati pemukati nekunze coil chichawedzera, uye capacitance yewaya keke pasi ichaderera.Naizvozvo, yekutanga resonance peak uye mupata pane iyo spectrum curve ichaenda kune yakaderera frequency kutungamira, uye anotevera nhongonya uye mipata ichafamba zvishoma kune yakakwirira frequency kutungamira.
