Feem ntau hais lus, kev sim tshuab ua haujlwm tsuas yog ob hom hais txog kev taw qhia (lossis kev siv dag zog): nro thiab compression. Ntau hom kev pom zoo tshaj plaws -xws li nro, compression, dabtsi yog khoov, shear, tev, tearing, puncture, thiab abrasion-xav txog cov hom kev ntxhov siab uas siv rau cov qauv. Hais txog kev tshawb nrhiav thiab kev tswj hwm: thaum cov no yog cov ntsiab lus sib txawv, lawv tsis sib cais. Hauv cov txheej txheem tshwj xeeb raws li kev sim tshwj xeeb, kev tswj hwm kev ua haujlwm feem ntau tswj tsuas yog ib qho kev txwv tshwj xeeb (piv txwv li, lub tshuab hluav taws xob tensile tester tswj kev txav ceev ntawm lub platform xeem). Hloov pauv, feem ntau muaj ntau yam kev tshawb nrhiav tsis pom; Ib qho hluav taws xob tensile tester, piv txwv li, feem ntau saib xyuas kev thauj khoom, hloov chaw, thiab deformation. Qhib-loop control tiv thaiv kaw-loop control.
Kev Tshawb Nrhiav Ranges thiab Tswj Ranges
- Kev kuaj pom ntau yam: Cov no ua haujlwm txhawm rau txhim kho kev ntsuas rhiab heev thiab daws teeb meem cuam tshuam nrog kev siv lub tshuab muaj peev xwm siab - los ntsuas qhov hnyav lossis ntsuas me me.
- Tswj ntau yam: Cov no yog siv los hais txog qhov yuav tsum tau ua kom muaj qhov tseeb thaum tseem ua kom qhov ntsuas qhov tseeb.
Kev sib raug zoo ntawm ntau yam -Tshwj xeeb Amplification thiab Measurement Range
Cov no yog cov ntsiab lus sib txawv tsis tau sib txheeb. Ntau yam - tshwj xeeb amplification yog hais txog ib qho tshwj xeeb ntawm lub sensor amplifier, whereas qhov ntsuas ntau yog hais txog lub ntiaj teb tus yam ntxwv parameter ntawm lub tshuab kuaj nws tus kheej. Rau cov neeg siv, tom kawg yog qhov tseem ceeb ntawm cov tswv yim, thaum tus qub tsis xav kom lawv mloog.
