Ua kūpaʻa ʻo Smart Weigh i ke kōkua ʻana i nā mea kūʻai aku e hoʻonui i ka huahana ma ke kumukūʻai hoʻemi.
Mea kākau: Smartweigh–Mea Kaumaha Poʻo Nui
ʻO ke kumu kumu a me ka ʻike hoʻohana ʻana o ka multihead weigher ʻO ka multihead weigher no ka neʻe ʻana a me ka sensor kaomi, ka mea maʻamau i hoʻohana ʻia i ke ana pololei o ka ʻikepili static a me ke ana pololei dynamic. 1. ʻO ka wehewehe ʻana o ka multihead weigher piha i ka gravity acceleration (g) o ka helu noi a me ka buoyancy (f) o ka wai kinoea, e like me ka hoʻololi ʻana o kekahi o nā mea i ana pololei ʻia (kūpono) i loko o nā mea i ana pololei ʻia (output). . ) e ana pololei i ka maikaʻi o ka mea ʻike ikaika. 2. ʻO ka manaʻo kumu o ka multihead weigher Polyurethane elastomer (vibration isolator, ʻoi aku ka sensitive beam) ke kumu o ka elastic deformation ma lalo o ka ikaika o waho, no laila ke ʻano o ke kūʻē ʻana i ke ana (transformation component) i hoʻopili ʻia ma luna o kona ʻili e hoʻopōʻino ai, a ʻo ke kūpaʻa ʻana i ke ʻano deforms Ma hope. ʻo ia, e hoʻololi ʻia kona kumukūʻai kū'ē (e hoʻonui a emi paha), a laila e hoʻohuli ʻia ka resistor i hōʻailona uila ma o ke ana pololei ʻana o ka mana lako kaapuni, a laila ke kaʻina holoʻokoʻa o ka hoʻohuli ʻana i ka ikaika o waho i hōʻailona uila. hoʻopau.
ʻAʻole paʻakikī ka ʻike ʻana i nā mea hoʻopaʻapaʻa kūʻē, polyurethane elastomers a me nā kaapuni mana hoʻāʻo he mau ʻāpana koʻikoʻi ʻaʻole hiki ke nele i ka resistor strain force multihead weigher. Ua wehewehe pōkole ʻia kēia mau pae ʻekolu ma lalo nei. 1. ʻO ke ana hoʻopaʻapaʻa kūʻē ʻO ke ʻano hoʻopaʻapaʻa kūʻē he ʻāpana o ka uea hoʻomehana uila i hoʻolaha ʻia ma luna o kahi substrate i hana ʻia me nā mea kūlohelohe, ʻo ia hoʻi, kahi mea hoʻohālikelike kūʻē.
ʻO kekahi o kāna mau palena nui ʻo ia ka dexterity index K. Ke kau ʻia kona mau ʻaoʻao ʻelua i ka ikaika F, hiki ke kikoo, ʻo ia hoʻi ke kumu o ka deformation. I ka manaʻo ʻana ua kikoo ʻia, ʻoi aku ka liʻiliʻi o kona ʻāpana keʻa, ʻo ia hoʻi, e emi ana kona ʻāpana kea.
ʻO ka pilina ma waena o ka coefficient elastic elastic o ke kū'ē kū'ē (ka hoʻololi pili o ka mea pale) a me ka elongation o ka uea hoʻomehana (ka hoʻololi pili o ka lōʻihi a me ka pōkole). Pono e kuhikuhi ʻia ʻo ka nui o ka index sensitivity index K he ʻāpana i hoʻoholo ʻia e nā hiʻohiʻona o ka mea maka no ka hana ʻana i ka uea hoʻomehana metala. ʻAʻohe mea pili i ka hiʻohiʻona a me ka nui o ke ʻano hoʻohālikelike. ʻO ka waiwai K o nā mea maka like ʻole ma ka 1.7—3.6 Kūwaena; ʻo ka helu K aʻe he mea nui ʻole, ʻo ia hoʻi, ʻaʻohe ana. I loko o ka ʻenekinia mechanics, kapa ʻia ʻo ΔL/L i ka ikaika strain, i kapa ʻia ʻo ε, a hoʻohana pinepine ʻia e hōʻike i ka nui o ka ductility, a he mea kūpono ʻole. Hoʻohana pinepine ʻia e like me ka hapa miliona o ka ʻoihana, i kapa ʻia ʻo με.
2. ʻO ka polyurethane elastomer ʻO ka polyurethane elastomer kahi māhele me kahi hiʻohiʻona kūikawā. ʻElua mau hana. ʻO ka mea mua, loaʻa iā ia ka ikaika o waho o ka multihead weigher, ka mea e hoʻokō ai ka ikaika recoil i kahi kaulike pili; ʻO ke kaha kū'ē kū'ē i hoʻopiliʻia i kēia wahi he mea kūpono ia no ka hana o kēlā me kēia lā o ka hoʻololiʻana i ka ikaika a me ka hōʻailona uila. 3. Ka nānā 'ana i ke kaapuni mana 'O ka hana o ka nānā 'ana i ka mana o ka mana, 'o ia ka ho'ololi 'ana i ka mea pale o ka 'au'au ho'opa'apa'a kū'ē i loko o ka puka uila hana.
No ka mea he nui nā pono o ka bridge Wheatstone, e like me ka hiki ke hoʻopau i ka pōʻino o ka hoʻololi ʻana i ka mahana, ke kāohi ʻana i ka mana o ka ikaika ʻaoʻao, a hiki ke maʻalahi i ka pilikia uku o ka multihead weigher, ua hoʻohana nui ʻia ke alahaka Wheatstone. ka mea kaupaona poʻo nui. hoʻohana. No ka mea ʻoi aku ka maʻalahi o ke kaapuni alahaka lima e like me ke kaulahao hōʻiliʻili piha, ua like nā ʻāpana nui o kēlā me kēia lima, a ua maʻalahi nā pōʻino o nā ʻano like ʻole e hoʻopau i kekahi i kekahi, no laila ke hoʻohana nei ka multihead weigher i ke kaulahao hōʻiliʻili piha a nā alahaka lima ʻē aʻe.
