Khoom Description
| Kev ua haujlwm ntawm square tube: | Cov khoom ntawm cov raj square feem ntau suav nrog plasticity, qaug zog, lub zog, hardness thiab cuam tshuam toughness. 1. Plasticity yog hais txog lub peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation yam tsis muaj kev puas tsuaj nyob rau hauv qhov kev txiav txim ntawm kev thauj khoom, uas yog ib qho tseem ceeb heev rau kev ntsuas kev ua tau zoo ntawm cov yeeb nkab square, uas yuav tsum tsis txhob saib xyuas thaum yuav khoom. 2. Kev qaug zog yog hais txog kev qaug zog ntawm cov yeeb nkab square nyob rau hauv cyclic load, uas cuam tshuam rau lub neej kev pab cuam ntawm cov khoom. Thaum yuav cov yeeb nkab square, xaiv cov khoom uas tsim nyog rau kev qaug zog raws li xav tau. 3. Lub zog yog hais txog lub peev xwm ntawm cov khoom siv hlau los tiv thaiv kev puas tsuaj nyob rau hauv qhov kev txiav txim ntawm cov khoom zoo li qub, uas tseem yog ib qho teeb meem uas yuav tsum tau hais txog thiab them nyiaj rau ntau yam haujlwm. Raws li kev sib txawv ntawm kev thauj khoom, nws tuaj yeem muab faib ua lub zog tensile, khoov lub zog, lub zog telescopic thiab lub zog shear. 4. Hardness yog hais txog qib hardness ntawm cov ntaub ntawv hlau, thiab cov lus qhia ntawm square tube hardness muaj xws li Rockwell hardness, ntaub hardness thiab Vickers hardness. 5. Kev cuam tshuam kev ua tau zoo kuj yog ib qho tseem ceeb Performance index, uas yog hais txog lub peev xwm ntawm hlau los tiv thaiv kev puas tsuaj nyob rau hauv kev cuam tshuam load. |
