C0041 Friction Coefficient Tester

Ena ke meter e sebetsang haholo ea likhohlano, e ka khethollang habonolo li-coefficients tse matla le tse tsitsitseng tsa lisebelisoa tse fapaneng, joalo ka lifilimi, polasetiki, pampiri, jj.

Coefficient ea likhohlano ke e 'ngoe ea thepa ea mantlha ea lisebelisoa tse fapaneng.
Ha ho na le motsamao o lekanyelitsoeng pakeng tsa dintho tse pedi tse kopanang
Kapa mokhoa o amanang le ho sisinyeha, sebaka sa ho kopana se hlahisa
Matla a sebetsang a sitisang motsamao o itseng ke khohlano
matla. Matla a khohlano a ntho e itseng a ka khethoa ke thepa
Ho hlahisa coefficient e matla le e tsitsitseng ea khohlano. Khohlano e tsitsitseng ke tse peli
Ho hanyetsa ho hoholo ha sebaka sa ho ikopanya qalong ea motsamao o amanang,
Karo-karolelano ea matla a eona ho matla a tloaelehileng ke coefficient of static friction; matla a khohlano a matla ke ho hanyetsa ha libaka tse peli tse hokahaneng li tsamaisana ka lebelo le itseng, 'me karolelano ea karo-karolelano ea eona ho matla a tloaelehileng ke coefficient ea khohlano e matla. Khokahano ea likhohlano ke ea sehlopha sa lipara tsa likhohlano. Ha ho na moelelo ho bua feela coefficient ea khohlano ea thepa e itseng. Ka nako e ts'oanang, hoa hlokahala ho hlakisa mofuta oa thepa e kopanyang para ea khohlano le ho hlakisa maemo a teko (mocheso oa mocheso le mongobo, mojaro, lebelo, joalo-joalo) le lisebelisoa tse thellang.

Mokhoa oa ho lemoha friction coefficient o batla o tšoana: sebelisa poleiti ea teko (e behiloeng tafoleng ea ts'ebetso e tšekaletseng), lokisa sampuli e le 'ngoe holim'a poleiti ea teko ka sekhomaretsi sa mahlakoreng a mabeli kapa mekhoa e meng, 'me u lokise sampole e' ngoe ka mor'a hore e sehe hantle. Selaeling se inehetseng, beha selaete bohareng ba sampole ea pele letlapeng la teko ho latela litaelo tse tobileng tsa ts'ebetso, 'me u etse hore tataiso ea liteko tsa lisampole tse peli li bapale le tsela e thellang le sistimi ea ho metha matla ha e hatellehe. Hangata sebelisa mokhoa o latelang oa mokhoa oa ho lemoha.

Lintlha tse latelang li tlameha ho hlalosoa bakeng sa tlhahlobo ea friction coefficient:
Pele ho tsohle, litekanyetso tsa mokhoa oa tlhahlobo bakeng sa coefficient ea likhohlano tsa lifilimi li thehiloe ho ASTM D1894 le ISO 8295 (GB 10006 e lekana le ISO 8295). Har'a bona, ts'ebetso ea tlhahiso ea boto ea liteko (eo hape e bitsoang benche ea liteko) e hloka haholo, eseng feela tafole ea tafole e tlamehang ho netefatsoa Boemo le boreleli ba sehlahisoa bo hlokoa hore bo etsoe ka lisebelisoa tse seng tsa makenete. Litekanyetso tse fapaneng li na le litlhoko tse fapaneng bakeng sa maemo a tlhahlobo. Mohlala, bakeng sa khetho ea lebelo la tlhahlobo, ASTM D1894 e hloka 150±30mm/min, empa ISO 8295 (GB 10006 e lekana le ISO 8295) e hloka 100mm/min. Mabelo a fapaneng a liteko a tla ama liphetho tsa liteko haholo.
Ea bobeli, teko ea ho futhumatsa e ka phethahala. Hoa lokela ho hlokomeloa hore ha tlhahlobo ea ho futhumatsa e etsoa, ​​mocheso oa slide o lokela ho netefatsoa hore o mocheso oa kamore, 'me feela boto ea teko e lokela ho futhumala. Sena se boletsoe ka ho hlaka ho ASTM D1894 standard.
Ntlha ea boraro, mohaho o tšoanang oa teko o ka boela oa sebelisoa ho lemoha coefficient ea likhohlano tsa tšepe le lipampiri, empa bakeng sa lintho tse fapaneng tsa teko, boima, stroke, lebelo le likarolo tse ling tsa slide li fapane.
Ea bone, ha u sebelisa mokhoa ona, u lokela ho ela hloko tšusumetso ea inertia ea ntho e tsamaeang tekong.
Ea bohlano, hangata, coefficient ea khohlano ea thepa e ka tlase ho 1, empa litokomane tse ling li boetse li bua ka taba eo khokahanyo e kholo ho feta 1, mohlala, khokahanyo e matla pakeng tsa rabara le tšepe e pakeng tsa 1 le 4.

Litaba tse hlokang tlhokomelo tekong ea friction coefficient:
Ha mocheso o ntse o eketseha, coefficient ea likhohlano tsa lifilimi tse ling e tla bontša mokhoa o ntseng o phahama. Ka lehlakoreng le leng, sena se khethoa ke litšobotsi tsa thepa ea polymer ka boeona, 'me ka lehlakoreng le leng, e amana le lubricant e sebelisoang ha ho etsoa filimi (lubricant e haholo E ka' na ea e-ba haufi le ntlha ea eona ea ho qhibiliha 'me ea fetoha e khomarelang. ). Ka mor'a hore mocheso o phahame, palo ea ho feto-fetoha ha sekhahla sa tekanyo ea matla e eketseha ho fihlela ketsahalo ea "stick-slip" e hlaha.
