Lub tshuab kuaj cov ntaub ntawv yog cov cuab yeej siv los ntsuas cov khoom siv ntawm cov khoom siv; Nws yog dav siv rau kev sim cov yam ntxwv xws li tensile lub zog, compression, dabtsi yog khoov, thiab shear nyob rau hauv cov ntaub ntawv xws li hlau, yas, roj hmab, thiab composites.
Cov khoom siv kuaj cov cav tov tuaj yeem muab faib ua ntau hom raws li cov qauv kev sim thiab daim ntawv thov scenarios, xws li universal test machines, fatigue test machines, and impact test machines. Lub tshuab ntsuas universal yog hom ntau tshaj plaws; muaj peev xwm ua tau ntau yam kev ntsuam xyuas txhua yam, nws yog tsim rau siv nyob rau hauv lub chaw soj nstuam thiab kev tswj xyuas zoo. Cov tshuab kuaj kev qaug zog feem ntau yog siv los ntsuas cov khoom siv ruaj khov nyob rau hauv lub voj voog thauj khoom thiab tau siv dav hauv cov haujlwm xws li aerospace thiab automotive manufacturing. Impact testing machines yog siv los soj ntsuam cov khoom ua tau zoo nyob rau hauv siab - ceev cuam tshuam loads, ua hauj lwm los ntsuam xyuas toughness thiab cuam tshuam tsis kam.
