Vim li cas xaiv cov khoom tseem ceeb hauv High -Speed Ferry Design
Hauv kev tsim thiab kev tsim kho ntawm High-Speed Craft (HSC), ib txwm steel tsis yog tus qauv lawm. Txhawm rau ua tiav qhov nrawm tshaj li 30 pob, cov neeg tsim nkoj tau ntsib cov teeb meem engineering nruj. Cov khoom uas tau xaiv ncaj qha cuam tshuam rau plaub yam tseem ceeb: ceev, roj efficiency, kev ncaj ncees, thiab cov nqi tu lub neej.
Qhov kev sib tw tseem ceeb hauv engineering rau niaj hnub ferries yog ntsuas qhov hnyav piv rau lub zog thaum muaj sia nyob huab cua marine corrosion thiab kom ntseeg tau zoo heev weldability hauv lub nkoj nkoj. Qhov no yog vim li cas lub nkoj tsim kev lag luam tau hloov mus rau marine- qib aluminium alloys. Los ntawm kev txo lub cev hnyav, ferries siv roj tsawg, nqa ntau dua, thiab ua kom muaj kev nyab xeeb hauv cov dej ntxhib.
Kev xaiv cov hlau tsis raug tuaj yeem ua rau kev ua haujlwm tsis zoo lossis cov nqi kho hnyav. Xa koj cov lus qhia txog qhov project rau GNEE hnub no. Peb cov kws tshaj lij cov ntaub ntawv marine yuav pab koj xaiv cov qib txhuas zoo thiab muab cov lus sib tw hauv 24 teev.
