Kupyolera mu kayeseleledwe ka nsalu zogwira manja ndi manja monga kukoka, kukanikiza, kukanikiza, kukanda ndi kusisita, makulidwe a nsalu, kupindika, kuponderezana, mikangano ndi mphamvu zolimba zimayesedwa, ndipo zizindikiro zisanu za makulidwe, kufewa, kuuma, kusalala ndi kutsekemera. kulimba kumapezedwa kuti awunike bwino kalembedwe kake ka nsalu.Oyenera zinthu wamba CHIKWANGWANI flake: nsalu nsalu, kunyumba nsalu nsalu, nonwoven nsalu, ulusi, magalimoto mkati, chikopa, pepala, etc.
Mfundo yoyesera yoyesa nsalu:
Zimatengera kumvera kwa dzanja la munthu pansalu.Ma indenters onse omwe amagwiritsidwa ntchito ndi mawonekedwe a cylindrical omwe amatsanzira zala za munthu ndi mizere yabwino, yomwe imagwiritsidwa ntchito kutengera zidindo za zala.Indenter imatenganso mawonekedwe a pamwamba ndi awiri pansipa kuti ayesere kukhudza kwa munthu.Dongosolo limawerengera ma index omwe akugwirizana nawo kudzera pakuyesa kwakuthupi kwakuthupi, monga kupsinjika, kupindika, kukangana ndi kukangana, ndipo amapeza makulidwe apamwamba, kufewa kwa SF, kuuma ST, kusalala kwa SM ndi tightness LT, kenako ndikuwunika mawonekedwe athunthu a nsalu.
1. Makulidwe index, makulidwe a nsalu wothinikizidwa ndi pamwamba yokhotakhota.
2. Mu gawo loyamba, pamwamba amapanikizidwa kupeza psinjika modulus ndi psinjika deformation, amene amasonyezedwa monga softness SF.
3. Mu gawo lachiwiri, kuyesa kupindika kumapeza kupindika kwakukulu, kupindika modulus, ntchito yopindika, ndi zina zotero, zomwe zimawonetsedwa ngati kuuma ST.
4. Mugawo lachitatu, mphamvu yothamanga kwambiri, kugunda kwapakati, kugundana kwa ntchito, ndi zina zotero, ndi sliding degree SM amapezedwa ndi kuyesa kwa mikangano.
5. Mu siteji ⅳ, ma tensile modulus, tensile work, etc. amapezedwa ndi kuyesedwa kolimba, komwe kumawonetsedwa ngati kulimba kwa LT.Kuwunika kwathunthu kwa zotsatira za mayeso: kalembedwe kake CH=A*SF+B*ST+C*SM+D*LT dongosolo lidzapeza SF, ST, SM, LT ndondomeko iliyonse imagawidwa kukhala imodzi, ziwiri, zitatu, zinayi, zisanu. .Mawonekedwe athunthu ndi kuchuluka kwa zolemera za kufewa, kuuma, kusalala ndi kulimba, ndipo ma coefficients A, B, C ndi D amatsimikiziridwa momveka bwino molingana ndi kagwiritsidwe ntchito, mtundu ndi zinthu zakuthupi.
Zogulitsa:
1. Zithunzi zofananira ndi manja a anthu
2. Kuwerengera zizindikiro kumapangitsa zotsatira kukhala zasayansi
3, ntchito yosavuta, makina amodzi muyeso umodzi wa zizindikiro zingapo
4. Kuphatikiza kwa chitsanzo cha makina ndi kuyesa thupi
5, zida ndi zotsika mtengo, zida zolondola kwambiri, zowongolera bwino, magwiridwe antchito okhazikika
