Curved Surface Slider (CSS): Friction Pendulum System (FPS) rau Seismic Isolation
Keywords: Curved Surface Slider, CSS, FPS, Sib Nqus Pendulum Bearing, TFPB, seismic isolation bearing, lead rubber bearing, LRB
Curved Surface Slider, feem ntau hu ua FPS (Friction Pendulum System), yog ib qho dav siv zawv zawg seismic cais ua raws li EN15129 cov qauv. Multi-curved nto kev sib txhuam pendulum bearings (TFPB, Triple Friction Pendulum Bearing) belongs rau advanced CSS series, uas yog tsim los ntawm Hebei Luze New Material Technology Co., Ltd.
Kuv, Txoj Cai Ua Haujlwm ntawm CSS / FPS
CSS ua haujlwm raws li pendulum mechanics. Lub ntsiab tivthaiv yog concave nkhaus zawv zawg interface. Thaum seismic excitation tshwm sim, cov articulated slider slides raws curved nto. Cov lus tsa suab no txuas ntxiv lub sij hawm ntawm kev vibration ntawm lub tsev thiab txuas hniav kom tsis txhob muaj seismic resonance. Seismic kinetic zog yog dissipated los ntawm kev sib txhuam ntawm stainless hlau daim hlau thiab siab -sliding composite cov ntaub ntawv. Kev cia siab ntawm cov qauv sib nqus thiab nkhaus geometry, cov kabmob nta txhim khu kev qha tus kheej - nruab nrab muaj peev xwm, tuaj yeem rov qab mus rau qhov qub chaw tom qab av qeeg yam tsis muaj kev hloov kho.
Multi-surface TFPB yog qhov hloov kho dua tshiab ntawm ib qho / ob chav concave FPS. Nrog rau ntau yam kev ywj pheej zawv zawg interfaces, nws ua tiav kev ua haujlwm tau zoo: av qeeg me me qhib qhov zawv zawg sab hauv; av qeeg nruab nrab thiab loj ua rau muaj ntau- txheej zawv zawg, ua kom tiav qib zog dissipation rau ze - txhaum thiab deb - thaj tsam seismic.
II, Qhov txawv ntawm Core: CSS-FPS VS LRB / HDR Roj Hmab Bearings
Ntau tus engineers tsis meej pem kev sib txhuam pendulum bearings nrog elastomeric isolators xws li Lead Rubber Bearing (LRB) thiab High Damping Rubber Bearing (HDRB). Lawv qhov sib txawv tseem ceeb yog teev hauv qab no:
Lub sij hawm yam ntxwv
FPS lub sijhawm cais tawm tsuas yog nyob ntawm qhov nkhaus nkhaus ntawm zawv zawg qhov chaw,ywj siab ntawm superstructure hnyav. LRB / HDR lub sij hawm yog rhiab heev rau ntsug load; kev ua tau zoo fluctuates thaum load hloov.
Tus kheej -qhov nruab nrab & durability
CSS tso siab rau lub ntiajteb txawj nqus kom rov pib dua. Tsis muaj roj hmab aging, creep los yog hardening teeb meem. Roj hmab bearings raug kev txom nyem ntev - lub sij hawm nkag mus, kev laus thiab kev ua haujlwm tsawg nyob rau sab nraum zoov.
Environmental adaptability
FPS ua haujlwm ruaj khov nyob rau hauv qhov tsis tshua muaj kub, raug ultraviolet thiab corrosive ib puag ncig. Cov khoom siv roj hmab degrade nyob rau hauv huab cua hnyav.
Qhov chaw nruab
FPS muaj qhov siab ntsug qhov siab, haum rau cov haujlwm uas muaj qhov txwv tshwj xeeb. LRB xav tau qhov loj dua ntsug.
Lub zog dissipation hom
FPS dissipates lub zog los ntawm kev sib txhuam saum npoo; LRB siv lub zog los ntawm cov yas deformation ntawm txhuas cores. HDR nyob ntawm cov roj hmab sab hauv hysteresis.
III, Cov Ntawv Thov Kev Sib Tham
Hebei Luze's TFPB multi- nkhaus nto sliders pab chaw ntau pob, tsev kho mob, tsheb thauj mus los hubs, ntev- ncua txuas hniav, siab- cov tsev nce siab thiab cov txheej txheem tseem ceeb. Piv nrog rau cov khoom siv cais tawm ib txwm muaj, CSS-FPS qhia kev ua haujlwm ruaj khov nyob rau hauv kev hloov pauv loj, hloov tau zoo dua rau cov qauv hnyav- thauj khoom.
Cov ntsiab lus
Raws li kev paub tab thiab qib siab seismic cais tawm, Curved Surface Slider FPS kov yeej ntau yam tsis xws luag ntawm cov roj hmab bearings. Multi-surface kev sib txhuam pendulum bearings muab hloov tau, txhim khu kev qha, ntev -lub sij hawm seismic tiv thaiv. Rau cov av qeeg niaj hnub no-kev tsim kho, CSS-FPS yog qhov nyiam txhua yam- nyob ib puag ncig los tiv thaiv- cov khoom seismic los tiv thaiv cov tsev thiab tib neeg lub neej.
