Elastic cov khoom ntawm cov tsheb nqaj hlau thiab taug qab kev yuav nqus tau
- Dab tsi yog cov ntsiab lus tseem ceeb ntawm cov khoom loj ntawm cov nqaj hlau?
Cov ntsiab lus tseem ceeb muaj cov modulus Elastic Haculus, stiffon txhav, txhav txhav txhav, thiab damping piv. Elastic maculus qhia cov khoom muaj peev xwm tiv taus deformation; ib tug qis loj clastic modulus qhia tau zoo elasticity. Static tawv tawv yog qhov piv txwv ntawm kev ntxhov siab kom lim hauv qab qhov qub; Txo cov tawv tawv stiffness tshwm sim hauv kev co damration damping. Dynamic tawv tawv nthuav tawm qhov tsis zoo nyob rau hauv cov khoom siv tsis muaj zog; Txo Quav Quav Nyim Taw Qhia Tau Zoo Dua Kev Txhim Kho Dynaming Damming. Ib qho kev npau taws ntau dua uas qhia tau lub zog ntau dua thiab muaj peev xwm ua kom zoo dua.
- Yuav ua li cas cov ntaub qhwv nrog cov khoom sib txawv elastic sib txawv hauv lawv cov txiaj ntsig ntawm cov nqaj hlau?
High - elasticity pads (xws li roj hmab cov ntaub qhwv thiab qis static cliffness, zoo heev Lawv tau dav siv hauv Urban Rail Transit thiab tuaj yeem txo lub suab nrov los ntawm 5 -} 10 decibels. Tsawg - elasticity pads (xws li cov ntaub qhwv zoo thiab tsis muaj peev xwm ua kom muaj peev xwm loj heev thiab kev siv hluav taws xob ntau dhau.
- Yuav ua li cas cov elastic propence ntawm kev tsheb nqaj hlau yog xaiv raws li tsheb ciav hlau ceev?
Siab - Cov tsheb ciav hlau ceev kev co kev ua haujlwm ntau zaus thaum lub sijhawm ua haujlwm nrog qis dua stiffness thiab ib tug siab damping piv. Piv txwv li, roj hmab cov ntaub qhwv nrog cov modulus elastic ntawm 30 {}}}}}} zaus vibrations thiab txhim kho kev thauj khoom zoo siab thiab txhim kho kev thauj khoom. Kev tsheb ciav hlau qis-ceev kev ua co colration zaus, yuav tsum tau muaj cov ntaub ntawv tsawg ntawm elasticity yuav tsum tau. Cov ntaub qhwv nrog cov tawv nqaij me ntsis, xws li cov ntaub qhwv yas, tuaj yeem siv los xyuas kom meej dua li cov txiaj ntsig basping thaum txo cov nqi.
- Yuav ua li cas cov elastic propales ntawm subrail pads hloov lub sijhawm?
Tom qab ntev -} siv siv, cov ntaub qhwv kev elasticity poob vim cov khoom laus thiab nkees. Qhov no nce cov modulity Elastic, zoo li qub thiab muaj zog txhav, thiab txo qhov kev co damping nyhuv. Piv txwv li, tom qab 3-5 xyoos ntawm kev siv, cov elasticity ntawm cov roj hmab cov ntaub qhwv yuav txo tau los ntawm 20%-ua rau kev nce tsheb ntau ntxiv. Cov teeb meem ib puag ncig xws li cov kub thiab cov huab cua ntau dua tuaj yeem ua kom nrawm elastic poob thiab luv lub ncoo kev ua haujlwm.
- Yuav ua li cas kuv tuaj yeem lees paub tias cov khoom loj ntawm subrail pads ua tiav cov cai ua haujlwm?
Siv cov khoom ntsuas tshuab los sim cov mapastic modulus thiab stiffomness. Siv cov khoom siv sib txawv sib txawv, ntsuas qhov deformation, thiab xam cov kev tsis cuam tshuam. Siv cov khoom siv tsis sib xws los tshawb xyuas cov khoom ruaj khov thiab damping sib piv, simulate cov tsheb ciav hlau zoo, thiab txheeb xyuas cov kab mob kis tau zoo. Nquag sim taug kev rau kev co thiab suab nrov. Yog tias kev co lossis suab qib siab tshaj cov qauv, cov ntaub qhwv cov khoom elastic tej zaum yuav tsis tau raws li cov cai.
