1: WW2 cuam tshuam li cas rau kev txhim kho clip?
Cov khoom tsis txaus ua rau kev ua kom zoo ntawm alloy. Standardization enabled loj ntau lawm. Portable installation cov cuab yeej tau tsim. Tom qab- kev tshawb fawb txog kev ua tsov rog tau txhim kho kev nkag siab ntawm kev qaug zog. Ntau cov qauv tsim niaj hnub taug qab mus rau 1940s kev tsim kho tshiab.
2: Dab tsi ua rau kev hloov ntawm spikes mus rau elastic fasteners?
Cov tsheb ciav hlau siab dua xav tau kev tswj kev co zoo dua. Cov neeg pw tsaug zog xav tau txoj kev fastening tshiab. Txo cov nqi tu kom tsim nyog tau txais kev nqis peev thawj zaug. Cov cai tswj kev nyab xeeb tau hloov mus rau kev tswj hwm cov txheej txheem elastic. Kev hloov pauv tiav tau siv sijhawm 30+ xyoo thoob ntiaj teb.
3: Yuav ua li cas lub computer modeling hloov clip tsim?
FEA hloov kev sim - thiab - yuam kev prototyping. Ntau-lub cev simulation soj ntsuam kev sib cuam tshuam hauv lub cev. Topology optimization txo qis kev siv cov khoom siv. Cov menyuam ntxaib digital pab kev sim virtual. Txo lub sij hawm loj hlob los ntawm 5 xyoo mus rau 18 lub hlis.
4: Dab tsi yog qhov tseem ceeb ntawm kev tsim kho xyoo 1990?
Corrosion-cov tshuaj tiv thaiv tau dhau los ua tus qauv. Automated ntau lawm txhim kho qhov sib xws. International cov qauv kev sib haum xeeb pib. Kev qaug zog lub neej kwv yees mus txog 10M mus. Thawj cov khoom sib xyaw tau qhia.
5: nanotechnology cuam tshuam li cas niaj hnub clips?
Graphene coatings txhim khu kev tiv thaiv corrosion. Nano-cov qauv hlau txhim kho toughness. Tus kheej- kho cov polymer sib xyaw yog nyob rau hauv kev sim. Deg texturing txo kev sib txhuam. Thermal spray nanoceramics ncua kev pab cuam lub neej.
