Zida Zachitsulo | R&D ya Ballistic Protection Systems for Modern Warfare Application

Kodi ballistic material ndi chiyani? Amagwiritsidwa ntchito kuti?
Zida zolimba zomwe zimagwiritsidwa ntchito kwambiri zimagwiritsa ntchito mbale za ceramic ngati zotchingira, koma ceramic imasweka pamphamvu ndikutaya mphamvu zake pankhondo yokhazikika. Zida zambiri zachitsulo zimakhala ndi vuto lomwelo la zipolopolo zomwe zimaphulika pogunda. Zidutswazi zimatha kuvulaza wovala zida. Ovala omwe amapaka zigamba zachiwiri pankhope zawo sangakhale omasuka ndikuwonjezera mtengo kwa munthu, kampani, kapena boma. Kupanga matekinoloje omenya nkhondo opepuka monga ndege ndi magalimoto amphibious, komanso kufunikira kowonjezera kuyenda kwa mphamvu zapansi, kumafunikira zida za ballistic zomwe zikupitiliza kuchepetsa kulemera kwa zida zankhondo ndikuwongolera magwiridwe antchito.
Zishango za Ballistic zimapezeka m'mitundu yosiyanasiyana komanso magiredi. Zidazi zimagwiritsidwa ntchito kuteteza galasi, zida zamagalimoto, zida zankhondo ndi zishango. Mapepala apulasitiki opangidwa ndi laminated amapereka chitetezo chochuluka, kuchokera ku galasi losindikizidwa losindikizidwa kupita ku zipangizo zapamwamba za ballistic. Zida za Ballistic nthawi zambiri zimakhala zolimba, koma zimatha kukhala zofewa. Zitha kukhala zovuta, monga Kevlar, UHMWPE, Lexan kapena carbon fiber composites, kapena zosavuta, mongaaluminiyamu, chitsulo, titaniyamu kapena ma aloyi ena.
Ndi kupita patsogolo kwaukadaulo, zida zankhondo za ballistic zasintha kwambiri. Msika wa malaya amkati otetezedwa ndi zipolopolo ukuwona kusintha komwe kuli kotetezeka komanso kopepuka. Izi zatsegula bwalo lankhondo latsopano laukadaulo wa Composite Metal Foam (CMF), ndikuchotsa m'malo azachipatala kuyambira ma bumpers agalimoto mpaka mawondo.
Zitsulo za thovu limodzi kapena zophatikizika ndizomwe zimayambitsa izi - izi ndi zithovu zamapangidwe ngati zitsulo zopanda kanthu, zomwe zimayikidwa mu zida za ballistic ngati chinthu chapakati, komanso zapakatikati pazogwiritsa ntchito zovuta monga chitsulo chankhondo, ceramics, ndi fiberboard. Chithovucho sichimangoyimitsa kuthamanga kwamphamvu kwa zipolopolo ndi zipolopolo, komanso kuziphwanya kwathunthu. Ngakhale zipolopolo zoboola zida, zopangidwira mwachindunji kung’amba zida zankhondo, sizingaloŵemo.
Kwa wankhondo, chitsulo cha thovu pazida zodzitetezera chimaphatikizapo:

• General Purpose Bulletproof Vests
• Zovala za Active Flotation Bulletproof Vests
• Zovala Zopanda Zipolopolo Zoyandama Zoyandama
• Zipewa zanzeru za ballistic
• Zida zotetezera za Ballistic pamapewa ndi mbali
• Ndi chitetezo cha visor ndi msana
• Zishango za Ballistic

Pazida zonyamula zida zolemera komanso zida zopulumukira, chitsulo cha thovu chimagwiritsidwa ntchito zosiyanasiyana kuphatikiza:

• Kupanga zida zophatikizika
• Kupanga mbale zamagalimoto zosagwira migodi
• Kupanga mabokosi oponyera ankhondo

Kodi Foam Metal ndi chiyani? Kodi Foam Metal ndi chiyani ndipo ndi zinthu ziti zomwe zimadabwitsa?
Chithovu chachitsulo ndi porous zitsulo zakuthupi zomwe zimapanga mawonekedwe atatu-dimensional mesh muzitsulo zachitsulo. Chifukwa pali pores ambiri m'thupichitsulo thovu, kukula, chiwerengero, kufanana, kugwirizanitsa ndi kusindikiza kwa pores kumakhudza katundu wake. Magawo omwe ali ogwirizana kwambiri ndi zitsulo za thovu amaphatikizapo kukula kwa pore, porosity yonse, porosity yogwira mtima, kachulukidwe ndi malo enieni.
Chithovu chachitsulo, monga mtundu watsopano wazinthu zokhala ndi zitsulo zonse komanso zinthu zina zapadera zazinthu zopanda zitsulo, zikulandira chidwi chochulukirapo. The katundu thovu zitsulo ndi motere:

• Zinthu zowala kwambiri (75-95% ya voliyumu imakhala ndi malo opanda kanthu)
• porosity kwambiri
• Mkulu compressive mphamvu pamodzi wabwino mphamvu mayamwidwe katundu
• Low matenthedwe madutsidwe
• Mphamvu zapamwamba

Impact mphamvu mayamwidwe mfundo ya thovu zitsulo
Kuphatikiza pa kugwiritsidwa ntchito pamalonda kusefera, kuchepetsa phokoso, kutchinjiriza ndi zonyamula zonyamula,zitsulo zitsulondi omwe ali oyenerera kuti agwiritse ntchito mumagulu a zida zophatikizika m'munda wamayamwidwe amphamvu.
Monga chida chodzitchinjiriza, chitsulo cha thovu ndi chinthu chopepuka, champhamvu champhamvu chopangidwa pogwiritsa ntchito zitsulo zopanda kanthu zomwe zimayikidwa muzitsulo zolimba zachitsulo. Nkhaniyi yawonetsa zinthu zabwino zamakina poyerekeza ndi zinthu zina zachitsulo. Makhalidwe apamwambawa a chitsulo cha thovu amakoka mphamvu mwachangu pa liwiro lapamwamba la ballistic velocity poyerekeza ndi quasi-static loading.
Zotengera zamagetsi zomwe zimapezeka pamalonda, zomwe nthawi zambiri zimatenga mphamvu zamakinetic pozipondereza kapena kuzipotoza pazovuta zamtunda wautali, zimagwira ntchito mofanana ndi akasupe, koma zimabwereranso, kuzipanga kukhala zida zosungira mphamvu m'malo motengera mphamvu.
Kapangidwe ka porous wa zitsulo thovu amawapatsa wapadera nkhawa-kupsyinjika pamapindikira; Kamodzi kupsyinjika ntchito kuposa extrusion phiri, chithovu amayamba compress pa kupsyinjika mwachilungamo nthawi zonse pafupifupi 50-70% kupsyinjika. Kuwonjezeka kwa piritsi la kupsyinjika / kupanikizika kumatanthawuza khalidwe la mpweya wabwino.

Kodi chitsulo cha thovu chimagwira ntchito bwanji pa zida zankhondo?
Chitsulo cha thovu chatsimikiziridwa kuti chimatchera zidutswa za zipolopolo ndikukutetezani ku zowonongeka zina zilizonse. Zida zambiri zamagulu ankhondo zimagwiritsa ntchito zida za Kevlar ngati gawo lakumbuyo, lomwe nthawi zambiri limavotera III-A ndipo limayimitsa kuzungulira kwa mfuti palokha. Zida zofewa zimayimitsa zipolopolo potaya mphamvu, ndipo popeza zipolopolo zambiri zapamanja sizikhala zakuthwa ngati zipolopolo zamfuti, muyenera kuzichepetsa kuti zisalowe pakhungu lanu. Chosanjikiza chachitsulo cha thovu ndi chotengera champhamvu cha zida zankhondo kuti zipolopolo zamphamvu zomwe zimafunikira zida zolimba kuti ziyime. Kukula kwa dongosolo lachitsulo thovuimasamutsa mphamvu yakugundana mocheperako kuposa zida zolimba. Pamalo okhudzidwa, chithovucho chimagwirizana mosavuta ndi chinthu chokhudzidwa. Kupindika kwa pulasitiki kumeneku kumatenga mphamvu zamakina. Mulimonse momwe zingakhalire, mphamvu yochepa kwambiri ya kugunda imatengedwa ndi zolimba. Anthu ena amasankhanso kuwonjezera gawo lachitatu kumbuyo kwa zida zofewa, zomwe zimatchedwa trauma pad. Iyi ndi pad yopangidwa ndi zigawo za madzi osakhala a Newtonian ndi padding. Imachepetsanso kukhudzidwa kwa zipolopolo kwa wovala.
