Elastomeric isolator 450% Qhov kawg Loj Deformation Test|Seismic Safety / Av qeeg tiv thaiv
450% qhov kawg loj deformation xeem yog qhov tseem ceeb ntawm kev ua tau zoo rau txhua hom seismic rho tawm roj hmab bearings, suav nrog LNR (Natural Rubber Bearing), Lead Rubber Bearing (LRB), thiab HIGH DAMPING RUBBER BEARING (HDR). Qhov kev ntsuam xyuas tseem ceeb no tau tsim tshwj xeeb los simulate qhov cuam tshuam ntawm cov av qeeg tsis tshua muaj av qeeg ntawm lub tsev thiab choj kev sib cais, ua kom muaj kev nyab xeeb ntawm cov qauv hauv siab - thaj tsam seismic.
Hauv 450% loj shear deformation xeem, seismic cais bearings-txawm LNR, LEAD RUBBER BEARING, los yog HIGH DAMPING RUBBER BEARING- yog raug rau cov qauv ntsug compression kev nyuaj siab thiab thawb mus rau qhov kawg shear strain ntawm 450%. Cov txheej txheem kev soj ntsuam nruj no ua kom pom tseeb qhov kawg deformation muaj peev xwm, cov qauv kev ruaj ntseg, thiab cov neeg kho tshuab kev ntseeg siab ntawm txhua hom kabmob nyob rau hauv kev ua haujlwm hnyav.
Rau LEAD RUBBER BEARING (LRB), 450% deformation kuaj xyuas qhov kev ncaj ncees ntawm cov hlau lead, kom ntseeg tau tias nws tsis tawg lossis ua tsis tiav thaum lub sijhawm tawg. Rau HIGH DAMPING RUBBER BEARING (HDR), qhov kev sim ua pov thawj tias kev ua haujlwm damping tseem nyob ruaj khov txawm tias qhov siab tshaj plaws deformation, tswj xyuas lub zog kom zoo kom txo tau qhov cuam tshuam seismic. LNR bearings, lub sijhawm no, raug sim rau cov roj hmab toughness thiab tsis kam rau tearing nyob rau hauv ultra- loj xaav.
Tus nqi tseem ceeb ntawm 450% qhov kawg deformation xeem yog nyob rau hauv kev tsim kom muaj kev ruaj ntseg hauv qab kab. Tus tsim shear deformation rau av qeeg tsis tshua muaj tshwm sim tsuas yog 250% mus rau 300%, txhais tau tias tag nrho cov roj hmab bearings tsim nyog -LNR, LEAD RUBBER BEARING, thiab HIGH DAMPING RUBBER BEARING- muab kev nyab xeeb coefficient ntawm ntau tshaj 1.5 npaug. Qhov kev rov ua dua no ua kom cov tsev, txuas hniav, thiab cov vaj tse tseem ceeb tsis txhob tawg thaum muaj av qeeg.
Cov chaw sim kws tshaj lij, xws li Hebei Luze Experimental Center, ua qhov kev soj ntsuam random thiab kuaj cov kabmob ntawm txhua qhov tshwj xeeb, suav nrog 800mm txoj kab uas hla LNR bearings, LEAD RUBBER BEARING (LRB) ntawm ntau qhov ntau thiab tsawg, thiab HIGH DAMPING RUBBER BEARING (HDR) rau kev sib txawv engineering. Tsuas yog cov kabmob uas dhau 450% loj deformation kuaj tau tso cai tawm hauv lub hoobkas.
Los ntawm kev xeem dhau 450% qhov kawg loj deformation xeem, LNR, LEAD RUBBER BEARING (LRB), thiab HIGH DAMPING RUBBER BEARING (HDR) tuav ruaj khov kab rov tav, txhim khu kev qha damping kev ua tau zoo, thiab zoo heev los tiv thaiv - deformation muaj peev xwm. Cov khoom no muaj -kev ua tau zoo seismic cais tawm muab kev tiv thaiv kev ntseeg siab rau kev tsim kho thoob ntiaj teb thiab cov phiaj xwm choj, tiv thaiv lub neej thiab khoom vaj khoom tsev hauv av qeeg- thaj chaw uas tuaj yeem ua tau.
