1. Lub cev muaj zog
Aluminium ua npuas ncauj khoomyog qhov tseem ceeb tshaj plaws ntawm lub teeb yuag, tsis tshua muaj ntom ntom, sib npaug ntawm lub zog loj, tab sis ntau tshaj 4 npaug ntau dua li cov khoom siv ua npuas ncauj. Lub conductivity ntawm cov khoom ua npuas ncauj yog ntau me dua li cov khoom txhuas, ntawm qhov tsis sib xws, qhov tsis kam yog loj dua, thiab nws yog tus neeg xyuas pib tsis zoo. Lub thermal conductivity ntawm txhuas ua npuas ncauj yog 0.1-0.2 npaug me dua li ntawm cov khoom tseem ceeb ntawm txhuas. Tsis tas li ntawd, cov npuas dej kuj muaj qhov zoo ntawm qhov tawv tawv, tsis muaj nplaim taws, tsis yooj yim rau oxidize, tsis yooj yim rau hnub nyoog, huab cua resistant, yooj yim rau recycle thiab lwm yam.
Rau cov khoom raug khoov, cov khoom siv yuav tsum muaj lub zog siab, thiab los ntawm kev sib piv cov nqi zog tshwj xeeb nrog cov txhuas ua npuas ncauj thiab qee yam khoom siv (aluminium thiab steel) (aluminium foam: steel = 5: 2.5: 1), Nws tau pom tias aluminium ua npuas ncauj muaj cov yam ntxwv tshwj xeeb muaj zog. Cov kev tshawb fawb sim tau pom tias kev kho cua sov kom zoo tuaj yeem ua kom nws lub zog. Yog li, aluminium ua npuas ncauj tuaj yeem tiv taus cov khoom loj loj.
2. Mechanical zog
Modulus ntawm elasticity, shear modulus, thiab elastic txwv ntawmaluminium ua npuas ncaujtxo qis raws li kev ua haujlwm exponential nrog qhov nce hauv porosity;
Tensile zog; ua npuas ncauj aluminium muaj lub zog tensile tsawg, tsis tshua muaj elongation thiab semi-nkig phenomenon. Nws tau pom tias qhov loj ntawm qhov pores muaj qhov cuam tshuam tseem ceeb ntawm lub zog tensile. Thaum cov txheeb ze ntom ntom zoo ib yam, lub zog tensile ntawm me pore loj yog ntau dua li qhov loj pore loj;
Compressive zog; lub zog tensile ntawm cov khoom ua npuas ncauj yog tsawg, tab sis lub zog compressive yog siab; nws compressive stress-strain nkhaus tuaj yeem muab faib ua linear elastic zone, yield plateau zone thiab ntom ntom. Foamed aluminium sib txawv aperture compression stress-strain nkhaus zoo ib yam, feem ntau nyob rau hauv qhov siab ntawm yas platform, qhov luaj li cas ntawm lub aperture yuav tsis tsuas yog ib tug linear kev sib raug zoo, tab sis yuav tsum nyob rau hauv ib tug tej yam aperture ntau yam kom ncav cuag tus nqi siab tshaj. . Foamed aluminium compression lub zog thiab ceev thiab compression tus nqi ntawm kev sib raug zoo ntawm daim duab qhia tau hais tias qhov ntau dua qhov ntom, qhov muaj zog compression;

3. Cov yam ntxwv ntawm kev nqus
Porous structural khoomtuaj yeem siv rau kev nqus. Qhov loj me ntawm lub rooj cob qhia ua lub luag haujlwm loj hauv lub zog nqus. Ua npuas ncauj hlwb me me, muaj zog thiab nqus cua sov zoo. Cov khoom ua npuas ncauj muaj lub siab ntev ntev thaum lub sij hawm compression thiab absorbs lub zog los ntawm kev nyuaj siab nyob rau hauv qhov tseem ceeb ntawm kev ntxhov siab. Lub tshuab nqus tsev yuav tsum muaj thaj tsam nyob rau hauv qhov kev ntxhov siab-txoj kev nkhaus, yog li lub zog nqus ntau dua thaum lub yielding platform siab dua thiab dav. Qhov pore loj muaj qee yam cuam tshuam rau qhov siab ntawm lub yielding platform, thiab xaiv qhov pore loj tuaj yeem txhim kho qhov kev nyiam ntawm lub yielding platform. Tsis tas li ntawd, nws lub zog nqus dej sib txawv tsis yog-monotonically nrog lub porosity, nyob rau hauv uas lub suction quab yuam yog loj tshaj ntawm ib tug tej yam porosity.
4. Damping kev ua tau zoo
Damping kev ua tau zoo yog lub peev xwm ntawm cov khoom siv los hloov cov tshuab kev co lub zog rau hauv thermal zog vim yog vim li cas sab hauv. Cov khoom siv tuaj yeem siv tag nrho los txo cov suab nrov thiab kev co. Ib txoj hauv kev tseem ceeb los txhim kho qhov kev ua tau zoo ntawm cov khoom siv hlau yog kom ua kom muaj kev sib cuam tshuam ntawm qhov tsis xws luag kom tau txais qhov siab tshaj plaws linear damping thiab txuas rau cov tshuab siv tshuab kom ua kom lub siab tsis zoo. Cov txiaj ntsig kev sim qhia tau hais tias cov ntaub ntawv ntxeem tau zoo sib xws nrog lub koom haum cov yam ntxwv ntawm cov khoom damped heev, thiab qhov muaj qhov hws muaj qhov cuam tshuam tseem ceeb ntawm cov lus teb damping ntawm qee cov ntaub ntawv uas tsis yog xim hlau lossis hlau.
