Matumba a m'manja nthawi zambiri amapangidwa ndi mapepala apamwamba kwambiri komanso apamwamba kwambiri, mapepala a kraft, makatoni oyera, mapepala amkuwa, makatoni oyera, ndi zina zotero. Ndizosavuta, zosavuta, komanso zimasindikizidwa bwino ndi mapangidwe apamwamba. Amagwiritsidwa ntchito kwambiri popaka zinthu monga zovala, chakudya, nsapato, mphatso, fodya ndi mowa, ndi mankhwala. Pogwiritsa ntchito matumba a tote, nthawi zambiri pamakhala vuto la kusweka pansi kapena zisindikizo zam'mbali za thumba, zomwe zimakhudza kwambiri moyo wautumiki wa thumba la mapepala ndi kulemera kwake ndi kuchuluka kwa zinthu zomwe zingagwire. Chochitika cha kusweka mu kusindikiza kwa matumba a mapepala opangidwa ndi manja makamaka kumagwirizana ndi mphamvu zomatira za kusindikiza. Ndikofunikira kwambiri kudziwa mphamvu zomatira za kusindikiza kwa matumba a mapepala okhala ndi manja kudzera muukadaulo woyesera.
Mphamvu zomatira zomata zamatumba a mapepala ogwidwa pamanja zimatchulidwa makamaka mu QB/T 4379-2012, zomwe zimafuna kusindikiza mphamvu zomatira zosachepera 2.50KN/m. Mphamvu yomatira yosindikiza idzatsimikiziridwa ndi njira yokhazikika yothamanga mu GB / T 12914. Tengani matumba awiri a zitsanzo ndikuyesa zitsanzo za 5 kuchokera kumapeto kwa thumba lililonse ndi mbali. Poyesa sampuli, ndi bwino kuika malo omangirira pakati pa chitsanzo. Pamene kusindikiza kumapitirira ndipo zinthuzo zimasweka, mphamvu yosindikiza imasonyezedwa ngati mphamvu yowonongeka ya zinthu panthawi yosweka. Werengani masamu amtundu wa zitsanzo za 5 pamapeto otsika ndi zitsanzo za 5 pambali, ndipo tengani zochepa za ziwirizo monga zotsatira zoyesa.
Mphamvu zomatira ndi mphamvu yofunika kuswa chisindikizo cha m'lifupi mwake. Chida ichi chimatengera mawonekedwe ofukula, ndipo cholumikizira chachitsanzocho chimakhazikitsidwa ndi chochepetsera chochepa. Chotchinga chakumtunda chimasunthika ndikulumikizidwa ndi sensor value value. Panthawi yoyesera, malekezero awiri aulere a chitsanzo amamangiriridwa muzitsulo zapamwamba ndi zapansi, ndipo chitsanzocho chimachotsedwa kapena kutambasula pa liwiro linalake. Mphamvu ya sensa imalemba mphamvu ya mphamvu mu nthawi yeniyeni kuti ipeze mphamvu zomatira za chitsanzo.
1. Zitsanzo
Tengani matumba awiri a zitsanzo ndikuyesa zitsanzo zisanu kuchokera kumapeto ndi mbali zonse za thumba. Zitsanzo m'lifupi ayenera kukhala 15 ± 0.1mm ndi kutalika ayenera osachepera 250mm. Poyesa zitsanzo, ndi bwino kuika zomatira pakati pa chitsanzo.
2. Khazikitsani magawo
(1) Khazikitsani liwiro loyesa ku 20 ± 5mm / min; (2) Khazikitsani chitsanzo m'lifupi 15mm; (3) Kutalikirana pakati pa zomangira kumayikidwa ku 180mm.
3. Ikani chitsanzo
Tengani chimodzi mwa zitsanzozo ndikumangirira nsonga zonse ziwiri zachitsanzo pakati pa zingwe zakumtunda ndi zapansi. Chingwe chilichonse chiyenera kumangirira m'lifupi mwake mwachitsanzo molunjika popanda kuwonongeka kapena kutsetsereka.
4. Kuyesedwa
Dinani batani la 'kukonzanso' kuti mukonzenso musanayese. Dinani batani la "Mayeso" kuti muyambe kuyesa. Chidachi chikuwonetsa mtengo wamphamvu munthawi yeniyeni. Mayesowo akamaliza, chotchingira chapamwamba chimakhazikitsidwanso ndipo chinsalu chikuwonetsa zotsatira zoyeserera za mphamvu zomatira. Bwerezani masitepe 3 ndi 4 mpaka zitsanzo zonse zisanu zitayesedwa. Dinani batani la "Statistics" kuti muwonetse zotsatira za ziwerengero, zomwe zikuphatikiza kuchuluka, kuchuluka, kuchepera, kupatuka kokhazikika, ndi kusiyanasiyana kwa mphamvu zomatira.
5. Zotsatira zoyeserera
Werengani masamu amtundu wa zitsanzo za 5 pamapeto otsika ndi zitsanzo za 5 pambali, ndipo tengani zochepa za ziwirizo monga zotsatira zoyesa.
Kutsiliza: Mphamvu yomatira ya chisindikizo cha thumba la pepala lokhala ndi manja ndilofunika kwambiri lomwe limatsimikizira ngati limakonda kusweka panthawi yogwiritsira ntchito. Pamlingo wakutiwakuti, imatsimikizira kulemera, kuchuluka, ndi moyo wa ntchito ya mankhwala omwe thumba la pepala logwira pamanja lingathe kupirira, choncho liyenera kuonedwa mozama.
