Feri yerekana feri nikimwe mubice byingenzi byumutekano bya sisitemu ya feri yimodoka.Feri yerekana feri igira uruhare rukomeye mugufata feri, kuburyo bivugwa ko feri nziza ya feri arinda abantu nimodoka.
Ingoma ya feri iba ifite inkweto za feri, ariko iyo abantu bahamagaye feri, berekeza kuri feri ninkweto za feri muri rusange.
Ijambo "feri yerekana feri" ryerekeza cyane cyane kuri feri yashyizwe kuri feri ya disiki, ntabwo ari feri ya feri.
Feri yerekana feri igizwe nibice bitatu byingenzi: ibyuma bifata ibyuma (isahani yinyuma), ibifatika, hamwe na blokisiyo yo guterana.Igice gikomeye cyane ni guhagarika guterana, ni ukuvuga formulaire yo guhagarika.
Inzira yibikoresho byo guterana igizwe nubwoko 10-20 bwibikoresho fatizo.Inzira iratandukanye kubicuruzwa nibicuruzwa, kandi iterambere rya formula rishingiye kubintu byihariye bya tekiniki yicyitegererezo.Abakora ibikoresho byo guterana amagambo babika formula zabo ibanga kubaturage.
Ubusanzwe asibesitosi byagaragaye ko ari ibikoresho byo kwambara neza, ariko nyuma yuko bimaze kumenyekana ko fibre ya asibesitosi yangiza ubuzima, ibi bikoresho byasimbujwe izindi fibre.Muri iki gihe, feri nziza ya feri ntigomba na rimwe kuba irimo asibesitosi, kandi sibyo gusa, igomba no kwirinda ibyuma birebire, bihenze kandi bitazwi neza fibre na sulfide bishoboka.Isosiyete ikora ibikoresho byo guteranya akazi igihe kirekire nugukomeza guteza imbere ibikoresho bishya kugirango tunoze imikorere yibikoresho bivangavanze, kurengera ibidukikije nubukungu
Ibikoresho byo guteranya ibintu ni ibintu bigize ibice bigize ibanze shingiro ni: gufatira: 5-25%;wuzuza: 20-80% (harimo guhindura modifike);gushimangira fibre: 5-60%
Uruhare rwa binder nuguhuza ibice byibikoresho hamwe.Ifite ubushyuhe bwiza nimbaraga.Ubwiza bwa binder bugira ingaruka zikomeye kumikorere yibicuruzwa.Binders zirimo
thermosetting resin: resin ya fenolike, ibisigarira byahinduwe bya fenolike, ibisigazwa bidasanzwe birwanya ubushyuhe
Rubber: reberi isanzwe
Ibisigarira hamwe na reberi bikoreshwa hamwe.
Abuzuza ibihimbano batanga kandi bigahindura imiterere yo guterana no kugabanya kwambara.
Uzuza ibihimbano: barium sulfate, alumina, kaolin, okiside y'icyuma, feldspar, wollastonite, ifu y'icyuma, umuringa (ifu), ifu ya aluminium…
Guhindura imikorere yubuvanganzo: grafite, ifu yo guterana, ifu ya reberi, ifu ya kokiya
Gushimangira fibre bitanga imbaraga zumubiri, cyane cyane mubihe by'ubushyuhe bwo hejuru.
Fibre ya asibesitosi
Fibre itari asibesitosi: fibre synthique, fibre naturel, fibre itari minerval, fibre yicyuma, fibre y ibirahure, fibre karubone
Ubuvanganzo ni ukurwanya kugenda hagati yimikoranire yibintu bibiri ugereranije.
Imbaraga zo guterana (F) zingana nigicuruzwa cya coefficient de fraisation (μ) hamwe nigitutu cyiza (N) mu cyerekezo gihagaritse hejuru yubuso, ibyo bikaba bigaragazwa na formulaire ya fiziki: F = μN.Kuri sisitemu ya feri, ni coefficente yo guterana hagati ya feri na disiki ya feri, naho N nimbaraga zikoreshwa na piston ya Caliper kuri padi.
Iyo coefficient de coiffe nini, imbaraga zo guterana ninshi.Nyamara, coefficente yubushyamirane hagati ya feri na disiki bizahinduka bitewe nubushyuhe bwinshi butangwa nyuma yo guterana amagambo, bivuze ko coefficient de fraisation ihinduka hamwe nubushyuhe bwubushyuhe, kandi buri feri ya feri ifite coefficient itandukanye yo guhinduranya umurongo kubera ibikoresho bitandukanye, so feri zitandukanye zifite ubushyuhe bwiza bwakazi butandukanye hamwe nubushyuhe bwakazi bukoreshwa.
Igikorwa cyingenzi cyerekana ibipimo bya feri ni coefficente yo guterana.Coefficient ya feri yigihugu isanzwe iri hagati ya 0.35 na 0.40.Niba coefficente yo guterana iri munsi ya 0.35, feri izarenga intera ya feri itekanye cyangwa birananirana, niba coefficient de frais iri hejuru ya 0.40, feri irashobora guhura nimpanuka zitunguranye no kuzunguruka.
Nigute ushobora gupima ibyiza bya feri

Ibyerekeye urusaku rwa feri
Urusaku rwa feri nikibazo cya sisitemu yo gufata feri kandi irashobora kuba ifitanye isano nibice byose bigize sisitemu yo gufata feri;ntamuntu numwe wigeze amenya igice cyigikorwa cya feri gisunika umwuka kugirango urusaku rwa feri.
- Urusaku rushobora guturuka ku bushyamirane butaringaniye hagati ya feri na disiki ya feri kandi bigatanga ihindagurika, imiraba yijwi ryiyi vibrasiya irashobora kumenyekana numushoferi uri mumodoka.0-50Hz urusaku ruke ntirwumvikana mumodoka, abashoferi 500-1500Hz ntibazabifata nkurusaku rwa feri, ariko 1500-15000Hz abashoferi b’urusaku rwinshi bazabifata nkurusaku rwa feri.Ibyingenzi byingenzi byerekana urusaku rwa feri harimo umuvuduko wa feri, ubushyuhe bwa padiri, umuvuduko wibinyabiziga nikirere.
. kwinjiza neza kunyeganyega, ntabwo bizatera urusaku rwa feri;muburyo bunyuranye, niba sisitemu yo gufata feri izamura neza kunyeganyega, cyangwa ndetse na resonance, irashobora Ibinyuranye, niba sisitemu ya feri yongereye kunyeganyega neza, cyangwa ikabyara resonance, irashobora kubyara urusaku rwa feri.
- Kuba urusaku rwa feri ntirusanzwe, kandi igisubizo kiriho ni ukongera guhindura sisitemu ya feri cyangwa guhindura gahunda muburyo bwibigize, harimo, byanze bikunze, imiterere ya feri.
- Hariho ubwoko bwinshi bwurusaku mugihe cyo gufata feri, bishobora gutandukanywa na: urusaku rutangwa mugihe cyo gufata feri;urusaku ruherekejwe n'inzira zose zo gufata feri;urusaku rutangwa iyo feri irekuwe.
Santa Brake, nkuruganda rukora feri yumwuga mu Bushinwa, rushobora guha abakiriya ibicuruzwa byiza byo gukora feri nziza nka kimwe cya kabiri cyuma, ceramic nicyuma gito.
Ibice bya feri yerekana ibyuma biranga ibicuruzwa.
