Cov kws tshawb fawb tau tsim ib hom tshiab ntawm thermoplastic polyurethane elastomer (TPU) shock absorber khoom

 

Cov kws tshawb fawb los ntawm University of Colorado Boulder thiab Sandia National Laboratory tau tsim kev hloov pauvshock-absorbing khoom, uas yog ib qho kev tsim kho tshiab uas tuaj yeem hloov pauv kev nyab xeeb ntawm cov khoom xws li cov khoom siv kis las mus rau kev thauj mus los.

Cov khoom tsim tawm tshiab no muaj peev xwm tiv taus qhov cuam tshuam tseem ceeb thiab tej zaum yuav sai sai rau hauv cov khoom siv ncaws pob, lub kaus mom caij tsheb kauj vab, thiab txawm siv rau hauv ntim los tiv thaiv cov khoom muag thaum lub caij tsheb thauj mus los.

Xav txog tias qhov kev poob siab-absorbing cov khoom no tuaj yeem tsis tsuas yog cuam tshuam lub cushion, tab sis kuj nqus tau ntau zog los ntawm kev hloov nws cov duab, yog li ua kom ntse dua.

Qhov no yog raws nraim li pab neeg no tau ua tiav. Lawv cov kev tshawb fawb tau luam tawm hauv phau ntawv xov xwm kev kawm Advanced Material Technology kom ntxaws, tshawb xyuas seb peb tuaj yeem ua tau zoo li cas ntawm cov khoom ua npuas ncauj. Cov ntaub ntawv ua npuas ncauj ua tau zoo ua ntej yuav raug nyem heev.

Ua npuas ncauj nyob txhua qhov chaw. Nws muaj nyob rau hauv cov cushions peb so, cov kaus mom peb hnav, thiab cov ntim khoom uas ua kom muaj kev nyab xeeb ntawm peb cov khoom lag luam online. Txawm li cas los xij, ua npuas ncauj kuj muaj nws cov kev txwv. Yog hais tias nws yog squeezed ntau dhau lawm, nws yuav tsis mos thiab elastic, thiab nws cov kev cuam tshuam kev nqus yuav maj mam poob.

Cov kws tshawb fawb los ntawm University of Colorado Boulder thiab Sandia National Laboratory tau ua qhov kev tshawb fawb tob txog cov qauv ntawm cov ntaub ntawv poob siab thiab tau thov cov qauv tsim uas tsis yog tsuas yog cuam tshuam nrog cov khoom nws tus kheej, tab sis kuj rau nws txoj kev npaj siv computer algorithms. Cov khoom damping no tuaj yeem nqus tau li ntawm rau lub zog ntau dua li cov qauv ua npuas ncauj thiab 25% ntau zog dua li lwm cov thev naus laus zis.

Qhov zais cia nyob rau hauv cov duab geometric ntawm cov khoom poob siab-absorbing. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv damping yog los nyem txhua qhov chaw me me hauv npuas ua ke kom nqus tau lub zog. Cov kws tshawb fawb tau sivCov khoom siv thermoplastic polyurethane elastomerrau 3D luam ntawv, tsim ib tug honeycomb zoo li lattice qauv uas vau nyob rau hauv ib tug tswj thaum muaj kev cuam tshuam, yog li zoo absorbing zog. Tab sis pab neeg xav tau ib yam dab tsi ntau dua universal, muaj peev xwm tswj tau ntau hom kev cuam tshuam nrog kev ua haujlwm zoo ib yam.

Txhawm rau ua tiav qhov no, lawv pib nrog kev tsim honeycomb, tab sis tom qab ntawd ntxiv cov kev hloov kho tshwj xeeb - cov pob me me xws li accordion bellows. Cov pob qij txha no yog tsim los tswj xyuas seb cov qauv honeycomb puas ploj mus raws li kev quab yuam, tso cai rau nws yooj yim nqus cov vibrations uas tsim los ntawm ntau yam cuam tshuam, txawm tias ceev thiab nyuaj los yog qeeb thiab mos.

Qhov no tsis yog theoretical xwb. Pab neeg tshawb fawb tau sim lawv cov qauv tsim hauv chav kuaj, nyem lawv cov khoom siv hluav taws xob hloov tshiab hauv qab cov tshuab muaj zog los ua kom pom nws cov txiaj ntsig. Qhov tseem ceeb tshaj, cov khoom siv cushioning high-tech no tuaj yeem tsim los ntawm kev lag luam 3D tshuab luam ntawv, ua rau nws tsim nyog rau ntau yam kev siv.

Qhov cuam tshuam ntawm kev yug me nyuam ntawm cov khoom siv shock-absorbing no loj heev. Rau cov neeg ncaws pob, qhov no txhais tau tias cov cuab yeej muaj kev nyab xeeb uas tuaj yeem txo qhov kev pheej hmoo ntawm kev sib tsoo thiab kev raug mob poob. Rau cov neeg zoo tib yam, qhov no txhais tau tias cov kaus mom caij tsheb kauj vab tuaj yeem muab kev tiv thaiv zoo dua hauv kev sib tsoo. Nyob rau hauv lub ntiaj teb dav dav, lub tshuab no tuaj yeem txhim kho txhua yam los ntawm kev thaiv kev nyab xeeb ntawm txoj kev loj mus rau txoj kev ntim khoom uas peb siv los thauj cov khoom tawg yooj yim.
