Ma quotation awiri a makina oyesera omangika amatha kuwoneka ofanana kwambiri — mphamvu yofanana, liwiro lofanana, mapulogalamu ofanana — ndipo amasiyanabe ndi katatu pa zomwe angathe kuyeza. Kusiyana kwake sikuli konse mu nambala ya mutu.
Nkhaniyi ikufotokoza magawo asanu omwe amasankha ngati makinawo akugwirizana ndi zomwe mukufuna, motsatira momwe amakhudzira zotsatira za mayeso. Yalembedwa kwa ogula poyerekeza zopereka, komanso kwa mainjiniya omwe ayenera kuteteza kugula mkati.
Mfundo zofunika kuziganizira
- Kuchuluka kwa zinthu kumakudziwitsani denga; kuchuluka kwa zinthu zomwe mungagwiritse ntchito kumakudziwitsani pansi. Zolakwika zambiri zoyezera zimachokera pakuyesa zinthu zomwe sizingakwanire mokwanira.
- Kulamulira kwa servo si chinthu chapamwamba — ndi chomwe chimapangitsa kuti kuyezetsa kupsinjika, kugwedezeka, ndi kupumula kukhale kotheka.
- Ma grips amaika malire a zinthu zanu kuposa momwe chimango chimachitira.
- Funsani satifiketi yoyezera ndi miyezo yomwe idatsimikiziridwa motsutsana nayo, osati chiwerengero cholondola chomwe chimanenedwa.
Yambani ndi lipoti lomwe mukufuna kupereka
Mafotokozedwe a makina amalembedwa kuti ayerekezedwe; malipoti oyesera amalembedwa kuti avomerezedwe. Chifukwa chake, poyambira kothandiza ndi tsamba lomaliza la lipoti lanu lamtsogolo - muyezo uti, mtengo uti, kulekerera kuti.
Kutalikitsa kwa kuyezetsa labu pakagwa filimu ya pulasitiki ku ASTM D882, kumamatira tepi ku ASTM D3330, ndi kuyika chivundikiro pa nsalu yolukidwa ku EN ISO 13934-1 kumafuna makina atatu osiyana kwambiri, ngakhale kuti onse atatu ndi "mayeso okhwima". Kugula imodzimakina oyesera okokaKuphimba zonse zitatu n'kotheka — koma pokhapokha ngati magawo asanu omwe ali pansipa atchulidwa pamodzi.
1. Kuchuluka kwa zinthu ndi kuchuluka kwa zinthu, osati nambala
Makina a 5 kN sali olondola pa 5 kN. Kulondola kumatsimikiziridwa pamlingo wodziwika bwino wa mphamvu, kotero selo lolemera lomwe limakhala lalikulu kwambiri limakhala losadalirika pang'onopang'ono pa mphamvu zomwe mafilimu ndi matepi amayesedwa.
Mphamvu yapamwamba kwambiri ndi mphamvu yogwirira ntchito sizili zofanana kwenikweni. Filimu yofewa yolongedza imatha kusweka pa 30 N; thumba lolukidwa la labotale lomwelo lingafunike 2 kN. Ngati sensa imodzi imaphimba zonse ziwiri, kuyesa kwa mphamvu yochepa kumakhala pafupi ndi pansi pa malo ake, komwe kumawoneka koipa kwambiri ndipo phokoso limawonekera pakhoma.
Lamulo lothandiza m'ma laboratories ambiri ndi lakuti mayeso a nthawi zonse azikhala mkati mwa theka la pamwamba la sensa, ndikusunga sensa yachiwiri, yotsika mphamvu pa zinthu zopyapyala. Mukayerekeza zopereka, funsani kuti ndi mtundu wanji wa sensa womwe ungagwiritsidwe ntchito - osati kuchuluka kwa sensa.
2. Kuwongolera liwiro kumasankha ngati deta yanu ikufanana
Ma polima, mafilimu ndi zomatira zimakhala zozungulira: mphamvu zawo zimatengera momwe mumakokera mwachangu. Sinthani liwiro la mutu wopingasa ndi mphamvu yochotsa, kutalika ndi modulus zonse zimasuntha, popanda kusintha kulikonse kwa zinthu.
Ichi ndichifukwa chake miyezo imafotokoza kuchuluka kwa kupsinjika kosalekeza m'malo mwa liwiro lapakati, ndipo chifukwa chake amakina oyesera a servo okhala ndi kompyutandiye maziko a labotale iliyonse yopereka deta yofanana. Choyendetsa cha liwiro lokhazikika kapena cha liwiro limodzi chingapangitse nambala; sichingapange yotetezeka.
Kuwongolera kwa Servo kumatsegulanso njira zozungulira zambiri — kupsinjika kosalekeza, kupsinjika kosalekeza, kuyendayenda ndi kupumula — zomwe sizingatheke pamakina omwe amadziwa kuyenda pa liwiro limodzi lokha. Ngati zinthu zomwe mumagwiritsa ntchito zikuphatikizapo ma gasket, ma seal kapena ma geotextiles, izi ndizofunikira osati njira ina.
3. Ma grips amasankha zomwe mungayese
Chimangochi ndi cha anthu onse; zinthu zogwirira ndi zogwirira ndi zomwe zimapangitsa makina kukhala oyenera nsalu, filimu, tepi, rabala kapena pepala. Ma laboratories awiri okhala ndi makina ofanana ndi magulu osiyanasiyana ogwirira adzapereka zotsatira zosiyana pa chinthu chomwecho.
Kulephera kofala kumakhala pa nsagwada, osati mu chitsanzo. Zingwe zogwirira zimalimbitsa mphamvu ndipo zimayambitsa kuphulika msanga pafupi ndi nsagwada pa filimu yopyapyala; zogwirira zozungulira ndi mpweya wolamulidwa zimagawa mofanana; thovu kapena elastomer zimafunika kugwira kosadula. Mayeso a nsalu amafunika nsagwada zazikulu mokwanira kuti zigwire m'lifupi mwa chitsanzo chonse popanda kutsetsereka.
Pa kuyesa kwa peel, geometry ndi yofunika monga momwe mphamvu: peel ya 90° ndi 180° ndi mayeso osiyana, ndipo chogwirira - osati makina - chimayika ngodya. Mawu omwe amalemba makina popanda kulemba seti yogwirira ndi mawu a theka la dongosolo.
4. Chiŵerengero cha zitsanzo ndi zomwe pulogalamuyo ingatumize kunja
Mphamvu ya peak ndi mfundo imodzi. Modulus, khalidwe la yield ndi mawonekedwe a failure curve zonse zimadalira kuchuluka kwa deta yomwe yatengedwa, komanso ngati pulogalamuyo ikhoza kuwerengera ma values omwe muyezo umapempha.
Kufufuza kawiri kothandiza. Choyamba, ngati pulogalamuyo imawerengera zotsatira zomwe zapezeka mwachibadwa - kutalika kwa kupsinjika kwina, modulus yobisika, mphamvu yosweka - kapena ngati wogwiritsa ntchito akuyembekezeka kuyikanso mu spreadsheet, komwe kutsata kumasowa mwakachetechete. Chachiwiri, ngati deta yosaphika ingatumizidwe kunja ndi curve yonse, chifukwa lipoti losonyeza chigamulo chokha ndi lovuta kuteteza kasitomala akamatsutsa gulu.
5. Kulimba kwa chimango ndi kulinganiza
Amakina oyesera a padziko lonse lapansiChimake chomwe chimapatuka pansi pa katundu chimadziyesa chokha komanso chitsanzocho. Pa zitsanzo zolimba cholakwikacho ndi chaching'ono; pa filimu yayitali komanso ulusi wopyapyala, kutsata bwino kwa crosshead ndi kusalinganika bwino kwa mizati kumatha kusintha zotsatira ndi kusiyana kwakukulu kuposa komwe mukuyesera kupeza pakati pa magulu.
Kulinganiza sikuoneka mu pepala lofotokozera, ndichifukwa chake ndikofunikira kufunsa lipoti lotsimikizira osati kujambula chimango. Kuti muwongolere khalidwe nthawi zonse, chofunikira ndi chochepa; kwa labotale yopereka deta yovomerezeka,ISO 7500-1Kutsimikizira kwa kalasi kwa chizindikiro cha mphamvu, pamodzi ndi cheke cha kusalala ndi kulinganiza, ndi umboni womwe chipani chachitatu chidzawunikadi.
Zinthu zitatu zomwe zikusoweka m'mawu ambiri
- Satifiketi yoyezera ndi muyezo wake wofotokozera. "Kulondola ± 0.5%" sikukutanthauza zambiri popanda kudziwa zomwe zatsimikiziridwa poyerekeza ndi kuchuluka kwa zomwe zagwiritsidwa ntchito.
- Mndandanda wa zida zonse zogwirira. Mtengo wosaphatikizapo zida zomwe mukufuna si wotsika mtengo.
- Malamulo a layisensi ya mapulogalamu ndi kukweza. Chilolezo chachiwiri cha malo ogwirira ntchito nthawi zambiri chimakhala kusiyana pakati pa wogwiritsa ntchito m'modzi ndi makina abwino ogwira ntchito.
Mndandanda wachidule wogulira
- Lembani muyezo uliwonse womwe labotale yanu iyenera kufotokoza motsutsana nawo, kenako lembani chilichonse malinga ndi mphamvu, liwiro ndi mtundu wa kugwira.
- Tchulani masensa awiri ngati zipangizo zanu zili ndi mphamvu yophwanya mphamvu yoposa imodzi.
- Imafuna servo control ndikutsimikizira kuti njira zozungulira zambiri zaphatikizidwa, osati kusankha.
- Pemphani kuti muwonetsedwe pa zinthu zanu, osati pa chitsanzo chachitsulo chokhazikika.
- Tsimikizirani kuti chitsanzo cha lipoti chikugwirizana ndi momwe makasitomala anu kapena bungwe lovomerezeka limayembekezera.
Lituo yakhala ikupanga zipangizo zoyesera zinthu ndi makina kuyambira mu 2008.makina oyesera a servo okhala ndi kompyutaMndandandawu umaphatikizapo kuyesa kwa kukanikiza, kupindika, kupindika, kumeta, kung'amba ndi kupeta, ndi njira zolimbikitsira nthawi zonse, kupsinjika nthawi zonse, kukwawa ndi kupumula, ndipo umaperekedwa ndi zida zosinthira ndi zogwirira za nsalu, filimu, tepi, rabala ndi pepala.Onani kuchuluka kwa mayeso okakamiza →
