Ngā ariā taketake me ngā pūkenga ngaio e whakamahia ana mō te pauna maha-upoko

Kaituhi: Smartweigh– Taumaha Upoko Maha

Ko te pauna maha-upoko he pūoko taumata wai kukume, he mea noa ake i roto i te whakatakotoranga raraunga ine tika me te ine tika hihiri. 1. Ko te whakamāramatanga o te pauna maha-upoko e whai whakaaro ana ki te kino o te whakaterenga o te kaha taumaha (g) me te pūmautanga mamaoa (f) mā te whakamahi i te wāhitau taipitopito, ā, e hangai ana ki te huri i tētahi o ngā mea i ine tika (papatipu) ki tētahi atu. Ine tika (putanga) He pūoko kaha mō te ine papatipu tika. 2. Ngā huānga taketake o te pauna maha-upoko Rauemi Polyurethane Ko te elastomer polyurethane (te wehewehe wiri, te hihi tairongo ake) ka arahi ki te whakarerekētanga rapa i raro i te mahi a te kaha o waho, kia puta ai te whakarerekētanga o te ine taumahatanga ātete (te taputapu hiko hurihanga) i whakapirihia ki tōna mata, ātete. I muri i te whakarerekētanga o te ine taumahatanga, ka puta he huringa (whanui, heke rānei) i tōna uara ātete, kātahi ka hurihia tēnei huringa ātete hei tohu raraunga o tētahi taputapu hiko mā roto i tētahi ara iahiko ine tika, ā, ka oti te whakawhiti i te kaha o waho hei tohu raraunga o te taputapu hiko. te tukanga katoa.

Ka kitea ko te ine taumahatanga ātete, te elastomer polyurethane rauemi polyurethane me te ara iahiko kimi he wāhanga nui e kore e ngaro i roto i te pauna maha-upoko momo whakatau ātete. Ka matapakihia pototia ēnei āhuatanga e toru i raro nei. 1. Ine taumahatanga ātete Ko te ine taumahatanga ātete he wahi ine taumahatanga ātete e hora ana i te waea whakamahana taputapu ahumahi ki runga i te pakitara, i te rauemi rānei i hangaia ki ngā rauemi waro.

Ko tētahi o ana tawhā matua ko te uara taupū mataara K. Ina pāngia ōna taha e te kaha F, tera pea ka piko, ka toro atu, arā, ka puta he āhua rerekē. Ki te mea ka piko, ka toro atu, ka whakaitihia tōna horahanga whakawhiti-wāhanga, arā, ka whakaitihia tōna radius porowhita whakawhiti-wāhanga.

Ko te tauwehenga ātete (te huringa ātete) o te ine taumahatanga ātete me te kaha kume (te huringa roa) o te waea whakamahana he hononga pai ki te tere noho. Me mōhio ko te whakatakotoranga o te uara tohu aro K he tawhā e whakahaerehia ana, e whakatauhia ana hoki e ngā āhuatanga o te rauemi mata mō te hanga i te waea whakamahana whakarewa. Kāore he pānga ki te āhua, te whakatakotoranga, te tauira me te whakatakotoranga o te ine taumahatanga ātete. Ko te uara he 1.7—3.6 Waenga; tuarua, ko te uara K he rahinga kore-ahu, arā, kāore he ahu. I roto i te turanga miihini, ko te ΔL/L e kiia ana ko te whakatau, e tohuhia ana ko ε, ā, e whakamahia ana hei whakaatu i te ahua o te kirihou he tino nui, he tino uaua, ā, ko te kotahi miriona o taua mea ka whakamahia hei kamupene, e tohuhia ana ko με.

2. Rauemi Polyurethane Elastomer Polyurethane Rauemi Polyurethane He wāhanga motuhake te elastomer Polyurethane. E rua āna mahi. I te tīmatanga, ko ia te kawenga mō te kaha o waho e pāngia ana e te pauna maha-upoko, ā, mā te kaha o waho ka puta he kaha tauhohenga hei whakarite i te taurite ōrite; He tika ake te ine taumahatanga ātete hei mahi i te mahi o ia rā o te huri i te tohu raraunga o te taputapu hiko. 3. Ara iahiko kimi Ko te mahi a te ara iahiko kimi ko te huri i te huringa ātete o te ine taumahatanga ātete ki te putanga ngaohiko paerewa mahi.

Nā te mea he maha ngā painga o te piriti Wheatstone, pērā i te kaha ki te pehi i te kino o te huringa pāmahana, te kaha ki te pehi i te kino o te taha taha, me te tere me te ngāwari o te whakaoti i te uauatanga o te pauna maha-upoko, nō reira kua riro mai te piriti Wheatstone i roto i te pauna maha-upoko. He whānui ngā whakamahinga. Nā te aro nui o te ara iahiko o te mekameka whakarārangi-katoa me ētahi atu piriti ringa, he rite tonu ngā tawhā taketake o ia ringa, ā, ka taea e ngā momo tūponotanga te whakataurite tetahi ki tetahi. ara iahiko.
