Mtengo wa C0044 Cornell Tester

The Cornell tester imagwiritsidwa ntchito kwambiri kuyesa ndikuwunika matiresi a kasupe. Pali njira zingapo zoyesera akasupe (kuphatikiza InnersPrings ndi BoxSprings). Zomwe zimazindikirika kwambiri zimaphatikizanso kuuma, kusungidwa kwa kuuma, kulimba, kukhudzidwa kwamphamvu, etc.

TheCornell Testeramagwiritsidwa ntchito poyesa kuthekera kwanthawi yayitali kwa matiresi kukana kulimbikira. Chidacho chimaphatikizapo kuthamanga kwapawiri kwa hemispherical komwe kungasinthidwe pamanja kutalika kwa axial. Sensa yonyamula katundu pa chosindikizira imatha kuyeza mphamvu yomwe imagwiritsidwa ntchito pa matiresi.

Mzere wa nyundo yopondereza umalumikizidwa ndi ma eccentric transmission osinthika komanso ma drive amagetsi osinthika amathamanga kwambiri mpaka nthawi 160 pamphindi.

Pamene mayesero ayesedwa, matiresi amayikidwa pansi pa nyundo yokakamiza. Sinthani kufalikira kwa eccentric ndi malo a shaft kuti akhazikitse mphamvu yogwiritsidwa ntchito pamalo apamwamba kwambiri komanso otsika kwambiri (malo otsika kwambiri 1025 N). Sensa yamalo pa chida imatha kuyeza malo a nyundo yokakamiza.
The eccentric kufala ndiye pang'onopang'ono mozungulira, kukweza ndi kukanikiza nyundo kuthamanga. Panthawi imodzimodziyo, deta ya kukakamizidwa ndi udindo idzalembedwa. Kulimba kwa matiresi kudzayezedwa kuchokera ku kukakamiza komwe kumachokera ku 75 mm mpaka 100 mm.
Pakuyesa, mutha kukhazikitsa miyeso 7 yoyeserera. Zizungulira 200, 6000, 12500, 25,000, 50000, 75000, ndi 100,000, ndipo zimamalizidwa nthawi 160 pamphindi. Miyeso isanu ndi iwiri yoyeserera imatha pafupifupi maola 10.5 nthawi, koma zotsatira zake ndi zabwino kwambiri chifukwa ndi zaka 10 zoyeserera matiresi.
Pamapeto pa mayeso aliwonse, gawo loyeserera lidzapanikizidwa pamatiresi pa 22 Newtons. Kuti mufananize kusiyanitsa kwa mphamvu yobwereranso ndi kutha kwa mayeso pambuyo pa mayeso, kudumpha kumayerekezedwa, ndipo kuchuluka kwake kumawerengedwa.
Pulogalamu yothandizira idzalimbikitsa mtengo womwe umapezedwa ndi masensa osiyanasiyana panthawi yoyeserera, ndikupanga lipoti lathunthu loyesa ndikusindikiza. Mtengo wopezedwa mwa kupeza chiwerengero cha miyeso yoyesera yomwe imayenera kumveka panthawi ya lipoti.
