Iingxowa zephepha eziphathwa ngesandla ngokubanzi zenziwe ngephepha elikumgangatho ophezulu kunye nomgangatho ophezulu, i-kraft paper, ikhadibhodi emhlophe eqatywe, iphepha le-copperplate, ikhadibhodi emhlophe, njl. Zisetyenziswa kakhulu ukupakishwa kweempahla, ukutya, izihlangu, izipho, icuba kunye notywala, kunye namayeza. Ngethuba lokusetyenziswa kweengxowa ze-tote, ngokuqhelekileyo kukho ingxaki yokuqhawula phantsi okanye kwiimpawu zecala zesikhwama, ezichaphazela kakhulu ubomi benkonzo yesikhwama sephepha kunye nobunzima kunye nobuninzi bezinto ezinokubamba. I-phenomenon yokuqhekeka ekutywinweni kweengxowa zephepha ezibanjwe ngesandla zihambelana kakhulu namandla okubambelela kokutywinwa. Kubaluleke kakhulu ukugqiba amandla okubambelela kokutywinwa kweengxowa zephepha ezibanjwe ngesandla ngokusebenzisa iteknoloji yokuvavanya.
Amandla okutywinwa okutywinwa kweengxowa zephepha eziphathwayo zichazwe ngokukodwa kwi-QB / T 4379-2012, efuna ukutywinwa kwamandla okunamathela okungekho ngaphantsi kwe-2.50KN / m. Amandla okutywinwa okutywinwa kuya kugqitywa yindlela yokunyamezela isantya kwi-GB / T 12914. Thatha iingxowa ezimbini zeesampuli kunye nokuvavanya iisampuli ze-5 ukusuka ekupheleni kwesikhwama ngasinye kunye necala. Xa isampuli, kuyacetyiswa ukuba ubeke indawo yokudibanisa phakathi kwesampuli. Xa ukutywinwa kuqhubekayo kunye nezinto eziqhekezayo, amandla okutywinwa abonakaliswe njengamandla obunzima bezinto eziphathekayo ngexesha lokwaphuka. Bala i-arithmetic mean ye-5 iisampulu kwisiphelo esiphantsi kunye neesampuli ezi-5 ecaleni, kwaye uthathe i-ezantsi kwezi zimbini njengesiphumo sovavanyo.
Amandla ancamathelayo ngamandla afunekayo ukuphula itywina lobubanzi obuthile. Esi sixhobo samkela isakhiwo esithe nkqo, kwaye i-clamping fixture yesampuli igxininiswe nge-clamp ephantsi. I-clamp ephezulu iyashukuma kwaye iqhagamshelwe kwi-sensor yexabiso lamandla. Ngethuba lovavanyo, iziphelo ezibini zamahhala zesampulu zinyanzeliswa kwii-clamps eziphezulu kunye nezantsi, kwaye isampuli ihlanjululwe okanye yolulwe ngesantya esithile. I-sensor yamandla irekhoda ixabiso lamandla ngexesha langempela ukufumana amandla okunamathela kwisampuli.
1. Isampuli
Thatha iisampulu ezimbini zeesampulu kwaye uvavanye iisampulu ezi-5 ukusuka kwicala elisezantsi kunye necala. Ububanzi besampulu kufuneka bube yi-15 ± 0.1mm kwaye ubude bube yi-250mm ubuncinane. Xa isampuli, kuyacetyiswa ukuba ubeke i-adhesive phakathi kwesampuli.
2. Seta iiparamitha
(1) Beka isantya sokuvavanya kwi-20 ± 5mm / min; (2) Beka isampuli ububanzi kwi-15mm; (3) Isithuba phakathi kweeclamps simiselwe kwi-180mm.
3. Beka isampuli
Thatha enye yeesampulu kwaye ubambe zombini iziphelo zesampulu phakathi kweeclamps eziphezulu nezisezantsi. I-clamp nganye kufuneka ibambe ngokungqongqo ububanzi obugcweleyo besampulu ngomgca othe ngqo ngaphandle komonakalo okanye ukutyibilika.
4. Uvavanyo
Cinezela iqhosha elithi 'seta ngokutsha' ukuseta kwakhona phambi kovavanyo. Cofa iqhosha elithi "Test" ukuqalisa uvavanyo. Isixhobo sibonisa ixabiso lamandla ngexesha langempela. Emva kokuba uvavanyo lugqityiwe, i-clamp ephezulu isetwa kwakhona kwaye isikrini sibonisa iziphumo zovavanyo lwamandla okunamathela. Phinda amanyathelo 3 kunye ne-4 de zonke iisampuli ezi-5 zivavanyiwe. Cinezela iqhosha elithi "Statistics" ukubonisa iziphumo zeenkcukacha-manani, ezibandakanya umndilili, ubuninzi, ubuncinci, ukutenxa okusemgangathweni, kunye ne-coefficient yokwahluka kwamandla okunamathela.
5. Iziphumo zovavanyo
Bala i-arithmetic mean ye-5 iisampulu kwisiphelo esiphantsi kunye neesampuli ezi-5 ecaleni, kwaye uthathe i-ezantsi kwezi zimbini njengesiphumo sovavanyo.
Isiphelo: Amandla okubambelela kwesitywina sesikhwama sephepha esibambe ngesandla siyinto ebalulekileyo emisela ukuba iyakwazi ukuchithwa ngexesha lokusetyenziswa. Ukuya kumlinganiselo othile, imisela ubunzima, ubungakanani, kunye nobomi benkonzo yemveliso leyo ingxowa yephepha ephathwa ngesandla inokumelana nayo, ngoko ke kufuneka ithathwe ngokungathí sina.
