Mechanical zog ntawm cov ntaub ntawv rau tshuab riam
Rau txhua tus chipper riam, ntawv txiav riam, shear hlau hniav los sis dej khov rov ua dua, peb txhua tus yuav tsum paub txog cov khoom, los ntawm cov ntaub ntawv peb yuav qhia tau hais tias lub tshuab riam ua tiav li cas. Thiab cov qhua tuaj noj mov muaj peev xwm tshwj xeeb ntawm cov khoom siv dag zog ntawm cov khoom riam tshuab.
Tom qab dab tsi yog cov khoom kho tshuab?
Mechanical zog yog cov txheej txheem ntawm cov khoom siv hlau rau kev siv tshuab riam thiab ib qho tseem ceeb ntawm cov khoom siv hauv kev siv los ua cov khoom tsim kho.
Cov tsis ua hauj lwm ntawm cov khoom siv hlau kom ua puas ntsoog yog hu ua khoom vaj khoom tsev (los yog khoom vaj khoom tsev). Lub siab los yog lub caij nplooj zeeg ntawm cov khoom siv hlau, kev txiav txim siab rau cov kev siv ntawm nws txoj kev siv thiab kev pab cuam lub neej ntawm cov khoom siv dag zog ntawm cov khoom siv hlau yog tsim los ntawm cov khoom thiab lub hauv paus loj thaum xaiv cov khoom, ntxiv rau lwm yam khoom vaj huam sib luag (xws li tensile, compression, torsion, feem cuam thiab cyclic ntsaws, thiab lwm yam.), cov khoom siv sib xyaw hlau ntawm cov khoom siv hlau yuav tsum kuj txawv.
Cov khoom siv sib dhos xws li: elasticity, plasticity, rigidity, aging rhiab heev, lub zog, hardness, feem ntau toughness, qaug zog zog thiab tawg toughness.
Elasticity: Ib qho khoom siv hlau uas deforms thaum nws raug sab nraud sab nraud, uas yuav rov qab tau cov khoom ntawm nws tus qauv zoo thaum sab nraud tawm.
Plasticity: lub peev xwm ntawm cov khoom siv hlau los tsim cov rhuav tshem mus tas li uas tsis ua rau puas tsuaj nyob sab nraud.
Kev kub taub hau: lub peev xwm ntawm cov khoom siv hlau los tiv thaiv elastic deformation hauv kev ntxhov siab.
Zog: lub peev xwm ntawm cov khoom siv hlau los tiv dhau rhaug thiab pob txha hauv qab rog.
Hardness: lub peev xwm ntawm cov khoom siv hlau tawm tsam kev tawm tsam ntawm qhov khoom nyuab dua.
Qhov teeb meem toughness: lub peev xwm ntawm cov ntaub ntawv hlau los ua txhaum hauv cov kev cuam tshuam.
Qaug zog lub zog: qhov siab tshaj plaws uas tsis ua rau pob txha tawg thaum cov khoom siv hlau yog rov ua dua lossis hloov lwm tus.
Tawv zuj zus: qhov kev ua tau zoo siv los qhia txog cov khoom muaj peev xwm los tiv tau qhov tsis muaj zog thiab nthuav dav.
