Ungayera sei kupfava kwepepa rechimbuzi/pepa remukati?

Kuyerwa kwekupfava kunoreva mamiriro ezvinhu apo, pasi pehupamhi hwemugero wekuyera, probe yakaita seplate inofamba ichikwira nekudzika ichidzvanya sampuli kusvika pakadzika kwemugero. Huwandu hwevheki yekuramba kwesampuli simba rekukotama uye simba rekukweshana pakati pemuenzaniso nemugero zvinoyerwa. Kukosha uku kunomiririra kupfava kwepepa.

 

Nzira iyi inoshanda kune mhando dzakasiyana dzepepa rechimbuzi rinodzivirira makwinya nezvimwe zvinobva mariri, pamwe chete nezvimwe zvigadzirwa zvepepa zvine zvinodiwa kuti zvive zvakapfava. Hazvishande kune napkin, tishu dzechiso dzakapetwa kana kunyorwa, kana bepa rine kuomarara kwakanyanya.

 

1. Tsananguro

Kupfava kunoreva huwandu hwevhekitori yekuramba kukotama kwemuenzaniso pachawo uye simba rekukweshana pakati pemuenzaniso nepakati apo probe yekuyera yakaita seplate inodzvanywa mupaka rehupamhi hwakati uye hurefu kusvika pakadzika pasi pemamiriro akatarwa nechiyero (yuniti yesimba i mN). Kana kukosha uku kuri kudiki, muenzaniso wacho unopfava.

2. Zviridzwa

Chishandiso ichi chinoshandisaMuedzo wekunyorova weYYP-1000,inozivikanwawo sechishandiso chekuyera kupfava kwepepa re microcomputer.

Chishandiso ichi chinofanira kuiswa patafura yakati sandara uye yakagadzikana, uye hachifanirwe kukanganiswa nemamiriro ekunze. Zvinhu zvakakosha zvechishandiso ichi zvinofanirwa kusangana nezvinodiwa zvinotevera.

 

 

 

3. Zviyero zvechishandiso uye kuongorora

3.1 Upamhi hweMupata

(1) Hurefu hwemitsetse yekuyedza zvishandiso hunofanira kukamurwa kuita mamakisi mana: 5.0 mm, 6.35 mm, 10.0 mm, uye 20.0 mm. Chikanganiso chehupamhi hachifanirwe kudarika ±0.05 mm.

(2) Kukanganisa kwehupamhi hwemitsetse nehupamhi, pamwe nekutarisa kufanana pakati pemativi maviri, zvinoyerwa uchishandisa vernier caliper (ine graduation ye0.02 mm). Avhareji yehukuru hwehupamhi pamagumo maviri nepakati pemitsetse ndiyo chaiyo hupamhi hwemitsetse. Musiyano uripo pakati payo nehupamhi hwemitsetse unofanira kunge uri pasi pe ±0.05 mm. Musiyano uripo pakati pehukuru hwepamusoro nehukuru hwepasi pakati pezviyero zvitatu inhamba yekukanganisa kufanana.

 

 

3.2 Chimiro cheprobe yakaita seplate

Kureba: 225 mm; Ukobvu: 2 mm; Radiyo yeArc yemucheto wekucheka: 1 mm.

 

3.3 Avhareji yekumhanya kweprobe uye daro rese rekufamba

(1) Kureba kweavhareji yekumhanya kwekufamba uye kureba kwese kweprobe, avhareji yekumhanya kwekufamba: (1.2 ± 0.24) mm/s; kureba kwese kwekufamba: (12 ± 0.5) nm.

(2) Kuongororwa kwedaro rose rekufamba uye avhareji yekumhanya kwekufamba kwemusoro wekuyera

① Kutanga, isa probe panzvimbo yakakwirira yenzvimbo yekufamba, yera kukwirira h1 kubva pamusoro penzvimbo yekubata uchishandisa geji yekukwirira, wobva wadzikisa probe kusvika panzvimbo yakaderera yenzvimbo yekufamba, yera kukwirira h2 pakati penzvimbo yepamusoro nepamusoro penzvimbo yekubata, wobva waisa daro rese rekufamba (mu mm) ndeiri: H=h1-h2

② Shandisa stopwatch kuti uverenge nguva inotora kuti probe ifambe kubva panzvimbo yepamusoro kuenda panzvimbo yakaderera, nemasekonzi 0.01 chaiwo. Nguva iyi ngairatidzwe sa t. Ipapo avhareji yekumhanya kwekufamba (mm/s) ndeiyi: V=H/t

 

3.4 Kudzika kweKuisa muSlot

① Kudzika kwekuisa kunofanira kunge kuri 8mm.

② Kuongorora kudzika kwechinhu chinopinzwa mugomba. Uchishandisa vernier caliper, yera kukwirira B kwechinhu chinopinzwa muchimiro cheplate. Kudzika kwechinhu chinopinzwa ndekwekuti: K=H-(h1-B)

4. Kuunganidzwa kweMienzaniso, Kugadzirira uye Kugadzirisa

① Tora sampuli zvichienderana nenzira yakajairika, gadzira sampuli, uye dziedze pasi pemamiriro akajairika.

② Cheka sampuli kuita zvidimbu zve 100 mm × 100 mm zvichienderana nehuwandu hwezvikamu zvakatarwa muchiyero chechigadzirwa, uye nyora mativi erefu uye akachinjika. Kutsauka kwehukuru munzira imwe neimwe kunofanira kuva ±0.5 mm.

③ Batanidza magetsi zvichienderana nebhuku rekushandisa rePY-H613 softness tester, gadzirira kupisa kwenguva yakatarwa, wobva wagadzirisa zero point yechishandiso, wogadzirisa hupamhi hweslit zvichienderana nezvinodiwa nekabhuku kechigadzirwa.

④ Isai masamples pachikuva chemuchina wekuyedza kupfava, uye muaite akaenzana sezvinobvira kusvika pamugero. Kune masamples ane layer yakawanda, arongedzei nenzira yepamusoro-pasi. Isai switch yekutevera peak yemudziyo panzvimbo yepamusoro, dzvanya bhatani rekutanga, uye probe yakaita seplate yemudziyo inotanga kufamba. Mushure mekunge yafambisa daro rese, verengai kukosha kwekuyera kubva pachiratidziro, uye mozoyera sampuro inotevera. Yerai mapoinzi gumi edata munzira dzakareba uye dzakachinjika zvakateerana, asi musadzokorora kuyerwa kwesample imwe chete.
