C0041 Ikizamini cya Coefficient Coefficient

Iyi ni metero ya coefficient ikora cyane, ishobora kumenya byoroshye coefficient ya dinamike kandi ihagaze yibikoresho bitandukanye, nka firime, plastike, impapuro, nibindi.

Coefficient de friction nimwe mumiterere yibanze yibikoresho bitandukanye.
Iyo hari isano ugereranije hagati yibintu bibiri bihuza hamwe
Cyangwa kugendana kugendagenda, guhuza isura bitanga
Imbaraga za mashini zibuza kugenda ugereranije ni uguterana
imbaraga. Imiterere yo guteranya ibintu runaka irashobora kugenwa nibikoresho
Kuranga coefficente yingirakamaro kandi ihagaze. Ubwumvikane buke ni bubiri
Kurwanya ntarengwa kwihuza hejuru yintangiriro yikigereranyo,
Ikigereranyo cyacyo nimbaraga zisanzwe ni coefficente ya static friction; imbaraga zo guterana imbaraga ni ukurwanya iyo ibice bibiri bihuza bigenda bigereranywa hagati yumuvuduko runaka, kandi ikigereranyo cyikigereranyo cyacyo nimbaraga zisanzwe ni coefficente yo guterana imbaraga. Coefficient yo guterana ni iyitsinda ryitsinda ryombi. Ntabwo bivuze kuvuga gusa coefficente yo guteranya ibintu runaka. Mugihe kimwe, birakenewe kwerekana ubwoko bwibintu bigize ibice byo guterana no kwerekana imiterere yikizamini (ubushyuhe bwibidukikije nubushuhe, umutwaro, umuvuduko, nibindi) Nibikoresho byo kunyerera.

Uburyo bwo gutahura coefficient de coiffure burasa nuburyo bumwe: koresha isahani yikizamini (ushyizwe kumeza ikora itambitse), shyira icyitegererezo kimwe kuri plaque yikizamini hamwe na kole ebyiri cyangwa ubundi buryo, hanyuma ukosore izindi sample nyuma yo gukata neza. Kuri slide yabigenewe, shyira igitereko hagati yicyitegererezo cyambere ku kibaho cyibizamini ukurikije amabwiriza yihariye yo gukora, hanyuma ukore icyerekezo cyibizamini byintangarugero zombi zijyanye nicyerekezo cyo kunyerera kandi sisitemu yo gupima imbaraga ntabwo ihangayikishijwe gusa. Mubisanzwe fata uburyo bukurikira bwo kumenya imiterere.

Ingingo zikurikira zigomba gusobanurwa kugirango ikizamini cya coefficient de friction:
Mbere ya byose, ibipimo byuburyo bwo gupima coefficient de fraux bishingiye kuri ASTM D1894 na ISO 8295 (GB 10006 bihwanye na ISO 8295). Muri byo, inzira yo gukora ikibaho cyibizamini (nanone yitwa intebe yikizamini) irasaba cyane, ntabwo ikibaho cyonyine kigomba kwemezwa Urwego nuburinganire bwibicuruzwa bisabwa gukorwa mubikoresho bitari magnetique. Ibipimo bitandukanye bifite ibisabwa bitandukanye kugirango ibizamini bishoboke. Kurugero, kugirango uhitemo umuvuduko wikizamini, ASTM D1894 isaba 150 ± 30mm / min, ariko ISO 8295 (GB 10006 ihwanye na ISO 8295) isaba 100mm / min. Umuvuduko utandukanye wibizamini bizagira ingaruka cyane kubisubizo byikizamini.
Icya kabiri, ikizamini cyo gushyushya kirashobora kugerwaho. Twabibutsa ko mugihe ikizamini cyo gushyushya gikozwe, ubushyuhe bwigitambambuga bugomba kwemezwa ko buri hejuru yubushyuhe bwicyumba, kandi ikibaho cyonyine kigomba gushyuha. Ibi byavuzwe neza mubisanzwe ASTM D1894.
Icya gatatu, imiterere imwe yikizamini irashobora kandi gukoreshwa kugirango hamenyekane coefficente yo guteranya ibyuma nimpapuro, ariko kubintu bitandukanye byipimishije, uburemere, inkoni, umuvuduko nibindi bipimo bya slide biratandukanye.
Icya kane, mugihe ukoresheje ubu buryo, ugomba kwitondera ingaruka za inertia yikintu cyimuka kukizamini.
Icya gatanu, mubisanzwe, coefficente yo guteranya ibintu iri munsi ya 1, ariko inyandiko zimwe na zimwe zivuga ku gihe aho coefficient de fraisque irenze 1, urugero, coefficente de frais de dinamike iri hagati ya reberi nicyuma iri hagati ya 1 na 4.

Ibintu bikeneye kwitabwaho mugupimisha coefficient yikigereranyo:
Mugihe ubushyuhe bwiyongera, coefficente yo guterana ya firime zimwe na zimwe izerekana inzira izamuka. Ku ruhande rumwe, ibi bigenwa n'ibiranga ibikoresho bya polymer ubwabyo, naho kurundi ruhande, bifitanye isano n'amavuta akoreshwa mu gukora firime (amavuta ni menshi Birashobora kuba hafi yo gushonga kandi bigahinduka ). Ubushyuhe bumaze kuzamuka, ihindagurika ryurwego rwo gupima imbaraga zipima kwiyongera kugeza igihe hagaragaye “inkoni-kunyerera”.
