Nkhani - Kugwiritsa Ntchito GMT mu Magalimoto

Galasi la Mat Reinforced Thermoplastic (GMT) ndi chinthu chatsopano, chosunga mphamvu, chopepuka chokhala ndi thermoplastic resin ngati matrix ndi galasi fiber mat ngati mafupa olimbikitsidwa. Pakadali pano ndi mtundu wa zinthu zophatikizana zomwe zimagwira ntchito kwambiri padziko lonse lapansi ndipo zimaonedwa ngati chimodzi mwa zinthu zatsopano za m'zaka za zana lino.

GMT nthawi zambiri imatha kupanga zinthu zopangidwa ndi mapepala omalizidwa pang'ono. Kenako imakonzedwa mwachindunji kukhala chinthu chomwe mukufuna. GMT ili ndi mawonekedwe apamwamba, yolimba kwambiri pakugunda, ndipo ndi yosavuta kuisonkhanitsa ndikuiwonjezera. Imadziwika chifukwa cha mphamvu zake komanso kupepuka kwake, zomwe zimapangitsa kuti ikhale chinthu choyenera kwambiri chomangira m'malo mwa chitsulo ndikuchepetsa kulemera.

1. Ubwino wa Zipangizo za GMT

1) Mphamvu yayikulu: Mphamvu ya GMT ndi yofanana ndi ya zinthu zopangidwa ndi polyester FRP zoyikidwa pamanja, ndipo kuchuluka kwake ndi 1.01-1.19g/cm. Ndi yaying'ono kuposa thermosetting FRP (1.8-2.0g/cm), chifukwa chake, ili ndi mphamvu yapadera kwambiri.

2) Yopepuka komanso yosunga mphamvu: Kulemera kwa chitseko cha galimoto chopangidwa ndiZinthu za GMTingachepe kuchoka pa 26 kg kufika pa 15 kg, ndipo makulidwe a kumbuyo angachepe kuti malo a galimoto awonjezereke. Mphamvu zomwe zimagwiritsidwa ntchito ndi 60%-80% yokha ya zinthu zachitsulo ndi 35%-50% ya zinthu za aluminiyamu.

3) Poyerekeza ndi thermosetting SMC (sheet molding compound), zinthu za GMT zili ndi ubwino wa nthawi yochepa yopangira zinthu, kugwira ntchito bwino, kubwezeretsanso zinthu, komanso nthawi yayitali yosungira zinthu.

4) Mphamvu ya GMT yoyamwa kugunda kwa galimoto ndi yokwera nthawi 2.5-3 kuposa SMC. SMC, chitsulo, ndi aluminiyamu zonse zinasweka kapena kusweka pamene zidagunda, koma GMT sinavulale.

5) Kulimba kwambiri: GMT ili ndi nsalu ya GF, yomwe imatha kusunga mawonekedwe ake ngakhale itakhala ndi mphamvu ya 10mph.

2. Kugwiritsa Ntchito Zipangizo za GMT Mu Gawo la Magalimoto

Mapepala a GMT ali ndi mphamvu zambiri ndipo amatha kupangidwa kukhala zinthu zopepuka. Nthawi yomweyo, ali ndi ufulu wopangidwa bwino, mphamvu yogundana imayamwa bwino, komanso magwiridwe antchito abwino. Amagwiritsidwa ntchito kwambiri m'makampani opanga magalimoto kuyambira m'ma 1990. Pamene zofunikira pakugwiritsa ntchito mafuta mopanda ndalama, kubwezeretsanso, komanso kusinthasintha kwa zinthu zikupitilira kukula, msika wa zida za GMT zamagalimoto upitiliza kukula mosalekeza.

Pakadali pano, zipangizo za GMT zimagwiritsidwa ntchito kwambiri mumakampani opanga magalimoto, makamaka kuphatikiza mafelemu a mipando, ma bumpers, zida zoimbira, ma hood, mabatire a batri, ma pedal a mapazi, malekezero akutsogolo, pansi, ma fender, zitseko zakumbuyo, madenga, katundu. Zigawo monga mabatire, ma visor a dzuwa, ma racks a matayala owonjezera, ndi zina zotero.

1) Chimango cha mpando
Kapangidwe ka galimoto yamasewera ya Ford Motor Company ya 2015 Ford Mustang (yomwe ili pachithunzi pansipa) yokhala ndi mzere wachiwiri wopangidwa ndi kampani ya Tier 1 supplier/converter Continental Structural Plastics pogwiritsa ntchito Hanwha L&C's 45% unidirectional glass-reinforced fiberglass mat thermoplastic Molds for composite materials (GMT) ndi Century Tool & Gage, compression molding. Imakwaniritsa bwino malamulo ovuta kwambiri achitetezo aku Europe a ECE osamalira katundu wonyamula katundu.

Chigawocho chinafunika ma FEA opitilira 100 kuti amalize, kuchotsa zigawo zisanu kuchokera ku kapangidwe kakale ka chitsulo. Ndipo chimasunga makilogalamu 3.1 pa galimoto iliyonse mu kapangidwe kowonda, komwe ndikosavuta kuyika.

2) Mzere woletsa kugundana kumbuyo
Mtambo woletsa kugundana womwe uli kumbuyo kwa galimoto yatsopano ya Hyundai ya Tucson (onani chithunzi pansipa) mu 2015 wapangidwa ndi zinthu za GMT. Poyerekeza ndi zinthu zachitsulo, galimotoyi ndi yopepuka ndipo ili ndi mphamvu zabwino zotetezera. Imachepetsa kulemera kwa galimoto komanso kugwiritsa ntchito mafuta pamene ikuonetsetsa kuti galimotoyo ikugwira ntchito bwino.

3) Gawo lakumaso
Mercedes-Benz yasankha Quadrant Plastic Composites GMTexTM yolimbikitsidwa ndi nsalu ya thermoplastic composites ngati zinthu zoyambira mu S-Class (yomwe ili pachithunzi pansipa) yapamwamba.

4) Gulu loteteza thupi
Quadrant PlasticComposites imagwiritsa ntchito GMTex TM yogwira ntchito bwino kwambiri poteteza pansi pa chivundikiro cha galimoto ya Mercedes Off-Road Special Edition.

5) Chimango cha kumbuyo
Kuwonjezera pa ubwino wamba wa kuphatikiza magwiridwe antchito ndi kuchepetsa kulemera, kupangika kwa mapangidwe a GMT tailgate kumathandizanso mitundu ya zinthu zomwe sizingatheke ndi chitsulo kapena aluminiyamu. Imagwiritsidwa ntchito pa Nissan Murano, Infiniti FX45, ndi mitundu ina.

6) Dongosolo la Dashboard
GMT imapanga lingaliro latsopano la mafelemu a dashboard omwe amagwiritsidwa ntchito pa mitundu ingapo ya Ford Group: Volvo S40 ndi V50, Mazda, ndi Ford C-Max. Zophatikizazi zimathandiza kuphatikiza zinthu zosiyanasiyana. Makamaka pophatikiza ziwalo zopingasa zamagalimoto monga machubu achitsulo chopyapyala mu chikombole. Poyerekeza ndi njira zachikhalidwe, kulemera kumachepetsedwa kwambiri popanda kuwonjezera mtengo.
