Chitsogozo Chokwanira cha Mayeso a Plastic Tensile mu Mafakitole Opangira Majekeseni

Chiyambi:

Kuyesa kwazinthu zamapulasitiki kumakhala kofunikira kwambiri pamafakitale omangira jakisoni.Dongosolo lofunikira kwambiri lowongolera khalidweli lapangidwa kuti liwunike bwino momwe makina amagwirira ntchito komanso magwiridwe antchito azinthu zapulasitiki.Mwa kuyika zidazi ku mphamvu zowongoleredwa zoyendetsedwa, opanga amatha kudziwa bwino mphamvu zawo ndi kulimba kwawo, kuwonetsetsa kuti zomaliza zimakwaniritsa miyezo yolimba yamakampani ndi zomwe makasitomala amayembekeza.Chitsogozo chatsatanetsatanechi chikuwunikira cholinga, kachitidwe, komanso kufunikira kwa kuyesa kwa zida zapulasitiki, ndikuwunikira gawo lake lofunikira pakusunga zinthu zapamwamba kwambiri.

1. Cholinga cha Kuyesa Kwamphamvu:

Cholinga chachikulu cha kuyesa kwamphamvu kwa zigawo za pulasitiki ndikuzindikira zofunikira zamakina azinthu zapulasitiki, kuphatikiza mphamvu zawo zolimba, mphamvu zokolola, kutalika kwa nthawi yopuma, ndi modulus ya Young.Izi zimagwira ntchito yofunikira kwambiri pakuwunika momwe zinthu ziliri, kulosera momwe zimakhalira zitalemedwa, ndikuwonetsetsa kuti zikuyenera kugwiritsidwa ntchito mwapadera.Popeza deta yolondola kudzera mukuyesa kolimba, opanga amatha kupanga zisankho zodziwika bwino paza kusankha kwazinthu ndi kukonza mapangidwe, zomwe zimapangitsa kuti ntchitoyo ikhale yodalirika komanso yodalirika.

2. Kukonzekera kwa Chitsanzo:

Kuyesa kwamphamvu kumafunikira kukonzekera zoyeserera zolondola komanso zoyimira.Zitsanzozi nthawi zambiri zimapangidwira kapena kupangidwa kuchokera ku zigawo zapulasitiki zomwe zikuwunikiridwa, kutsata miyeso ndi masinthidwe apadera omwe amafotokozedwa mumiyezo yoyenera monga ASTM D638 kapena ISO 527. Kukonzekera mosamala kwa zitsanzo zoyesa kumatsimikizira zotsatira zodalirika komanso zosagwirizana panthawi yoyesera.

3. Zida Zoyezera Zovuta:

Pamtima pazigawo zapulasitiki zoyezetsa zolimba pali makina oyesera padziko lonse lapansi (UTM).Chida chapaderachi chimakhala ndi nsagwada ziwiri zogwira - imodzi yogwira mwamphamvu choyesa ndipo inayo imagwiritsa ntchito mphamvu yokoka yolamulidwa.Mapulogalamu apamwamba a UTM amalemba ndikusanthula mphamvu yogwiritsidwa ntchito ndi data yofananira pakuyesa, ndikupanga ma curve ofunikira opsinjika.

4. Njira Yoyezetsa Zovuta:

Kuyesa kwenikweni kwamphamvu kumayamba ndikumangirira mosamala zitsanzo zoyeserera mkati mwa UTM grips, kuwonetsetsa kugawidwa kofanana kwa mphamvu yomwe imagwiritsidwa ntchito.Mayeserowa amachitidwa pa liwiro losalekeza, pang'onopang'ono kutambasula chitsanzocho mpaka chikafika pa fracture.Panthawi yonseyi, UTM imalemba mosalekeza kuchuluka kwa mphamvu ndi kusamuka, kulola kusanthula mwatsatanetsatane momwe zinthuzo zimachitikira pansi pa kupsinjika kwamphamvu.

5. Kusonkhanitsa ndi Kusanthula Deta:

Pambuyo poyesa, deta yojambulidwa ya UTM imakonzedwa kuti ipange curve-strain curve, chithunzithunzi chofunikira chakuyankhidwa kwa zinthu zomwe zimagwiritsidwa ntchito.Kuchokera pamapindikirawa, zinthu zofunika kwambiri zimatengedwa, kuphatikiza mphamvu zolimba kwambiri, mphamvu zokolola, kutalika kwa nthawi yopuma, ndi modulus ya Young.Magawo owerengekawa amapereka chidziwitso chofunikira pamakina amakina, zomwe zimathandiza opanga kupanga zisankho zoyendetsedwa ndi data pakukula kwazinthu ndi njira zowongolera.

6. Kutanthauzira ndi Kuwongolera Ubwino:

Zomwe zapezedwa pakuyezetsa kolimba zimawunikidwa mosamala kuti awone ngati zinthu zapulasitiki zimakwaniritsa zofunikira ndi miyezo.Ngati zotsatira zigwera mumtundu womwe ukufunidwa, zigawo zapulasitiki zimaonedwa kuti ndizoyenera kugwiritsidwa ntchito.Mosiyana ndi izi, zokhota zilizonse kapena zofooka zilizonse zimapangitsa opanga kukonza kapena kusintha kofunikira, kutsimikizira kupanga zida zapulasitiki zapamwamba kwambiri.

Pomaliza:

Kuyesa kwa pulasitiki kumayima ngati mzati wofunikira pakuwongolera zabwino m'mafakitole omangira jakisoni.Poyika zida zapulasitiki ku mphamvu zowongoka zoyendetsedwa ndikuwunika bwino makina awo, opanga amatha kuwonetsetsa kuti zinthu zawo zimakwaniritsa miyezo yapamwamba kwambiri yamakampani.Pokhala ndi deta yolondola, opanga amatha kupanga zisankho zodziwika bwino za kusankha kwazinthu, kusinthidwa kwa mapangidwe, ndi kupititsa patsogolo kwazinthu zonse, potsirizira pake amapereka zigawo zapulasitiki zodalirika komanso zogwira ntchito kwambiri kwa makasitomala awo.
