Nyob rau hauv lub seismic systems ntawm loj tej yaam num xws li vaj tse, txuas hniav thiab nuclear fais fab nroj tsuag, lub Friction Pendulum Bearing (FPB luv luv) yog undoubtedly ib tug tseem ceeb tivthaiv. Tso tseg txoj kev cai "rigid resistance" seismic concept, nws tso siab rau cov qauv ntawm lub cev yooj yim thiab cov khoom siv kho tshuab ruaj khov los tsim kom muaj kev ruaj ntseg zoo rau cov qauv tsim hauv "kev tiv thaiv yooj yim".
Dab tsi yog Friction Pendulum Bearing (FPB)?
Kev sib txhuam pendulum bearing yog ib qho seismic cais cov kabmob uas tsim los ntawm txoj cai pendulum ua ke nrog zawv zawg kev sib txhuam zog dissipation. Nws lub luag haujlwm tseem ceeb yog "kev sib cais" lub sab sauv ntawm lub tsev ntawm nws lub hauv paus. Tsis muaj cov cuab yeej siv hluav taws xob zoo tswj, nws ua tiav ntau yam haujlwm los ntawm peb qhov tseem ceeb:
- Spherical oscillation: Thaum av qeeg tshwm sim, cov qauv sab sauv oscillates raws tus kheej kheej ntawm cov kabmob, buffering seismic cuam tshuam zoo li lub pendulum.
- Kev sib txhuam zog dissipation: Thaum lub sij hawm oscillation, kev sib txhuam ntawm qhov chaw sib chwv dissipates seismic zog xa mus rau cov qauv, txo kev puas tsuaj rau lub tsev.
- Lub ntiajteb txawj nqus nws tus kheej -centering: Tsav los ntawm nws tus kheej lub ntiajteb txawj nqus, cov qauv cia li rov qab mus rau nws qhov qub chaw tom qab av qeeg yam tsis muaj kev cuam tshuam los ntawm phau ntawv.
- Nyob rau hauv luv luv, nws integrates seismic cais, lub zog dissipation thiab nws tus kheej -center functions, zoo thaiv seismic zog thiab sai kho cov qauv stability tom qab av qeeg.
Cov txiaj ntsig tseem ceeb ntawm FPB: Muaj kev ntseeg siab dua li cov kabmob ib txwm muaj
Piv nrog rau roj hmab seismic cais bearings thiab zoo tib yam zawv zawg bearings, FPB daws tau ntau yam mob cov ntsiab lus ntawm tsoos bearings nrog zoo zoo:
(1) Ultra-siab ntsug bearing muaj peev xwm
Nws tuaj yeem tiv taus ntsug loads ntawm ntau txhiab mus rau kaum tawm txhiab tons, ua kom haum rau cov qauv hnyav xws li super siab-nce vaj tse, ntev- txuas txuas thiab nuclear fais fab chaw yam tsis muaj teeb meem muaj peev xwm.
(2) Tus kheej zoo heev - muaj peev xwm nyob nruab nrab
Ua tiav tsis siv neeg rov pib dua tshiab los ntawm lub ntiajteb txawj nqus, nws ua rau qhov seem seem ntawm cov txheej txheem hloov chaw tom qab av qeeg. Tsis muaj kev kho phau ntawv yuav tsum tau, tso cai rau lub tsev rov ua haujlwm sai thiab txo qis kev poob qis.
(3) Durability thiab stability
Ua los ntawm kev hnav tshwj xeeb-tiv taus thiab corrosion{1}} cov ntaub ntawv tiv taus, nws tiv taus huab cua, kev laus thiab qaug zog. Nws txoj kev pabcuam lub neej sib luag ntawm cov qauv hauv tsev loj, yuav tsum tau saib xyuas me ntsis thiab txiav cov nqi sijhawm ntev -.
(4) Kev siv dav dav
Tsis txwv los ntawm lub tsev hnyav lossis qhov chaw, nws ua tau zoo hauv ob qho tib si me me av qeeg txhua hnub thiab av qeeg loj heev. Nws kuj yoog mus rau cov kev ua haujlwm nyuaj xws li cov qauv deformation tshwm sim los ntawm kev hloov pauv kub thiab tsis sib xws.
Core Application Value ntawm FPB
FPB yog ntau tshaj li ib qho kev txhawb nqa yooj yim - nws yog "kev pov hwm seismic txoj cai" rau cov haujlwm loj hauv engineering. Nws tuaj yeem txo cov txheej txheem nrawm teb los ntawm 60% -80% thaum muaj av qeeg, txo qis kev puas tsuaj rau cov khoom tseem ceeb xws li kab teeb, kab thiab phab ntsa, thiab tiv thaiv cov khoom siv sab hauv thiab cov neeg ua haujlwm.
Nws yog tshwj xeeb tshaj yog haum rau cov tsev tseem ceeb hauv qab no:
- Lifeline tej yaam num: Cov tsev kho mob, cov chaw khaws ntaub ntawv thiab cov chaw ceev xwm ceev, uas yuav tsum tau ua haujlwm thaum muaj av qeeg.
- Irreplaceable tej yaam num: Cov tsev relics kab lis kev cai, hla- hiav txwv txuas hniav thiab nuclear fais fab nroj tsuag, uas yuav tsum tau FPB los xyuas kom meej qhov siab tshaj plaws kev nyab xeeb raws li reconstruction tsis yooj yim sua.
- Hauv cov ntsiab lus, kev sib txhuam pendulum bearing siv lub ntsiab lus "pendulum" rau engineering, daws cov kev sib tw seismic nruj tshaj plaws nrog cov kev cai tseem ceeb tshaj plaws ntawm physics, ua rau nws yog cov khoom lag luam nyob rau hauv niaj hnub seismic cais technology.
