Kushanda: Nyanzvi dzeMaindasitiri Dzinonyevera Nezvengozi dzeKuchengetedzeka Mukugadzirwa Kwezvinhu Zvisina Kurongeka
Munyika ine njodzi huru yekudzivirira simbi, maitiro ekumanikidza ekugadzira zvinhu zvisiri zvesimbingowani dzebhorayave chinhu chakakosha pakuchengetedza mauto, mapurisa, uye nyanzvi dzekuchengetedza. Vanhu vari muindasitiri uye kufambira mberi kwetekinoroji munguva pfupi yapfuura zvinoratidza kuti maitiro ekuumba asina kunaka anogona kukanganisa zvakanyanya mashandiro engowani, nepo kugadzira nemazvo kuchivimbisa kutevedzera mitemo yepasi rose yekuchengetedza uye kuwedzera mwero wekurarama kwevashandisi.
Kwete simbingowani dzebhora, ikozvino ndiyo nzira yeindasitiri nekuda kwekureruka kwayo uye kunyaradzwa kwayo kwepamusoro kana tichienzanisa nedzimwe nzira dzesimbi dzekare, dzinoshandisa zvinhu zvemhando yepamusoro zvakaita searamid (Kevlar), ultra-high-molecular-weight polyethylene (UHMWPE), uye carbon fiber. Zvinhu izvi zvakagadzirwa semachira akaiswa mudumbu (prepregs) uye zvinoumbwa kuburikidza nekumanikidza molding—maitiro apo tembiricha, kumanikidzwa, uye dhizaini yemold zvinosarudza zvakananga kunaka kwechigadzirwa chekupedzisira. “Padanho rekuumba ndipo panogadzirwa kugona kwekudzivirira kwengowani,” anotsanangura kudaro Dr. Elena Marquez, nyanzvi yesainzi yezvinhu paInternational Ballistic Protection Association (IBPA). “Kunyangwe kusawirirana kudiki mukugoverwa kwekumanikidzwa kana kudzora tembiricha kunogona kugadzira kusasimba kwechimiro kunokundikana kana paine kukanganiswa.”
Njodzi dzeKuumbwa Zvisina Kunaka
Kugadzira simbi dzemhando yepamusoro dzinoshandiswa zvakanyanya mukugadzira zvinhu zvisingadhuri, zvinowanzoita kuti pave nekumanikidzwa kusina kuenzana kunogumira panzira dzakamira. Chikanganiso ichi chinokonzera ukobvu hwesimbi dzengowani husingaenderane, kunyanya muchikamu chepamberi apo nzvimbo iri kudzika zvishoma inowana simba shoma rekudzvanya. Data rekuyedza kubva kuIBPA rinoratidza kuti ngowani dzisina kuumbwa zvakanaka dzinowanzoratidza kudzika kwekudzika kwemberi kunopfuura 30mm kana dzichiiswa mapfuti emhando ye54-type pistol (445±10m/s), zvichikundikana kusangana nemutemo weGA 293-2012 weChina unorayira kudzika kwe30mm pakurovera kwepamberi. Pamusoro pezvo, kumanikidzwa kusina kuenzana kunokuvadza zvivakwa zvefiber pamativi engowani, zvichideredza kuramba kwezvidimbu zvine kumhanya kwakanyanya—neV50 values (kumhanya uko 50% yezvidimbu zvinopinda) zvichidzika pasi pe610m/s inodiwa yakatsanangurwa muGJB 5115A-2012 standards.
Kuumbwa kusina kurongeka kunotungamirawo pakusanganiswa kusina kukwana kwe resin pakati pemachira efiber. "Kana prepregs dzisina kumanikidzwa zvakaenzana, mapoketi emhepo anoumbwa, uye kugoverwa kwe resin kunova kusina kurongeka," anodaro Mark Williams, director wekugadzira pakambani inotungamira mukugadzira magiya e ballistic. "Maburi aya anoshanda senzvimbo dzisina simba, zvichibvumira ma projectiles kana shrapnel kupinda mungowani kana kuendesa simba rakawandisa re kinetic mumusoro wemunhu akapfeka." Kukanganisika kwakadaro kwakabatana nekuwedzera kwe40% munjodzi dzekukuvara kweuropi mumiedzo yemunda, zvichienderana neongororo ya2025 yakaburitswa muOrdnance Material Science and Engineering.
Kuumba Nemazvo: Nzira Yekudzivirira Kwakanaka
Kufambira mberi mu tekinoroji yekudzvanya kwe isostatic kuri kugadzirisa matambudziko aya nekushandisa kumanikidzwa kwakaenzana kubva kumativi ese, vachitevedzera musimboti waPascal.
Zviyero zvakakosha mukuumbwa kwakanyatsonaka zvinosanganisira kudzora tembiricha (170–180℃ yezvinosanganiswa zvephenolic resin), mwero wekumanikidzwa (7–8kg/cm²), uye nguva yekugara (maminetsi 10–15). Masisitimu anoshanda otomatiki anotarisisa izvi zvinoshanduka panguva chaiyo, achidzivirira kupisa kwakanyanya kunoparadza maUHMWPE fibers (anoda tembiricha iri pasi pe130℃) kana kusadzvanywa zvakanyanya kunosiya ma layers akabatana zvisina kusimba. Maitiro aya anobatanidzawo nzira dzekucheka mucheto, zvichideredza kukuvara kwemupendero wefiber mushure mekuumbwa kunogona kukanganisa simba rechimiro.
Kudanwa kweIndasitiri kweKutarisirwa Kwemhando Yepamusoro
Sezvo kudiwa kwengowani dze ballistic pasi rose kuri kuwedzera, masangano anotonga ari kusimbisa kunaka kwekuumba mumabasa ekupa zvitupa. NIJ (National Institute of Justice) muUS neChina Ministry of Public Security ikozvino inoda kuti vagadziri vatumire magwaro emaitiro ekuumba pamwe chete nemigumisiro yekuyedzwa kwemhedzisiro. "Chitupa chengowani
"n inongovimbika chete kana kugadzirwa kwayo kwakafanana," anodaro Marquez weIBPA. "Vatengi vanofanira kuona kuti vagadziri vanoshandisa matekinoroji ekuumba nemazvo, kwete kungovimba nemhando yezvinhu zvakagadziriswa."
Kune vanoshandisa pfuti, zvinoreva izvi zvakajeka: kugona kwengowani kuponesa hupenyu kunoenderana nekuoma kwemaitiro ayo ekuumba. "Kana mapurisa akapfekangowani yebhora, vanovimba kuti ichashanda kana yanyanya kumanikidzwa,” Williams anowedzera kudaro. “Kuvimba ikoko kwakavakirwa muforoma—apo mainjiniya akanyatsogadzirwa anoshandura shinda dzakasanganiswa kuita dziviriro isingapindiki.”
Nekuvandudzwa kwetekinoroji kuri kuramba kuchivandudza matekiniki ekuumba, indasitiri iri kuswedera pedyo nekubvisa zvikanganiso zvinogona kudzivirirwa, ichiva nechokwadi chekuti avo vari pamberi vanokwanisa kuwana zvishandiso zvinosangana nemazinga epamusoro ekuchengetedza uye mashandiro.
