Ua ntej, nws yog ib qho tsim nyog los qhia meej cov ntsiab lus thiab qhov sib txawv ntawm cov roj hmab buffers thiab dampers, vim tias ob lo lus feem ntau siv sib hloov tab sis muaj qhov sib txawv me ntsis. Cov roj hmab tsis siv feem ntau ua haujlwm kom nqus tau lub zog tam sim ntawd, txo cov quab yuam xa mus rau cov qauv tiv thaiv lossis khoom siv thaum sib tsoo, pib- nce, lossis kaw. Nws ua raws li "kev poob siab absorber" rau kev cuam tshuam tam sim ntawd, tiv thaiv kev puas tsuaj los ntawm kev quab yuam ntau dhau. Ib qho roj hmab damper, ntawm qhov tod tes, tsom rau kev txo qis kev co tsis tu ncua, hloov lub zog vibrational rau hauv thermal zog lossis lwm yam ntawm lub zog los ntawm kev sib txhuam ntawm cov khoom siv roj hmab, yog li txo qis kev co amplitude thiab suab nrov. Hauv kev siv tswv yim, ntau yam khoom siv ua ke ob qho tib si ua haujlwm, hu ua roj hmab tsis muaj - dampers, uas tuaj yeem ua rau muaj kev cuam tshuam thiab kev vibration ib txhij.

Roj hmab buffers thiab dampers tuaj yeem muab faib ua ntau hom raws li cov qauv, daim ntawv thov scenarios, thiab cov qauv kev ua haujlwm. Los ntawm kev xav ntawm cov qauv tsim, cov hom tseem ceeb muaj xws li cylindrical roj hmab buffers, conical roj hmab buffers, phaj roj hmab dampers, thiab composite roj hmab dampers. Cylindrical thiab conical hom yog dav siv nyob rau hauv lub teeb mus rau nruab nrab - khoom siv thauj khoom vim lawv cov qauv yooj yim, yooj yim installation, thiab tus nqi qis. Phaj roj hmab dampers yog haum rau loj - cheeb tsam kev co cais, xws li nyob rau hauv lub tsev hauv pem teb thiab cov cuab yeej siv tshuab. Cov khoom sib xyaw ua ke ua ke nrog cov roj hmab nrog cov hlau, cov dej ntws, lossis lwm yam khoom siv los txhim kho kev thauj khoom -cov kabmob muaj peev xwm thiab kev ua haujlwm tsis zoo, hloov mus rau siab -xav tau qhov xwm txheej zoo li aerospace thiab siab - kev thauj mus los ceev.
Nyob rau hauv cov nqe lus ntawm kev ua hauj lwm cov hauv paus ntsiab lus, roj hmab buffers thiab dampers cia siab rau lub cim viscoelastic zog ntawm cov ntaub ntawv roj hmab. Roj Hmab yog ib yam khoom siv viscoelastic, txhais tau tias nws nthuav tawm ob qho tib si elastic thiab viscous yam ntxwv. Thaum muaj kev cuam tshuam los yog kev vibration, cov khoom siv roj hmab tau deformation: lub elastic tivthaiv khaws lub zog thiab rov ua haujlwm, thaum lub viscous tivthaiv dissipates lub zog los ntawm kev sib txhuam hauv molecular, hloov vibrational lossis cuam tshuam lub zog rau hauv tshav kub uas tawm mus rau ib puag ncig. Qhov no dual mechanism ua rau cov roj hmab buffers thiab dampers zoo txo qhov cuam tshuam quab yuam thiab kev vibration amplitude yam tsis muaj kev puas tsuaj rau cov khoom tiv thaiv. Rau cov khoom sib xyaw, cov khoom siv hlau muab cov qauv kev txhawb nqa thiab thauj khoom- cov kabmob muaj peev xwm, thaum cov khoom siv roj hmab yog lub luag haujlwm rau kev poob siab thiab kev co txo qis, ua kom muaj txiaj ntsig zoo.
Cov ntaub ntawv tseem ceeb txiav txim siab qhov kev ua tau zoo ntawm cov roj hmab buffers thiab dampers, thiab kev xaiv cov khoom siv roj hmab muaj feem xyuam nrog cov xwm txheej ntawm daim ntawv thov. Cov khoom siv roj hmab tseem ceeb siv suav nrog cov roj hmab ntuj (NR), cov roj hmab hluavtaws, thiab cov roj hmab hloov pauv. Cov roj hmab ntuj muaj elasticity zoo heev thiab toughness, ua rau nws haum rau dav - lub hom phiaj buffers nyob rau hauv qis - kub, tsis yog - corrosive ib puag ncig. Cov roj hmab hluavtaws, suav nrog hydrogenated nitrile roj hmab (HNBR), ethylene propylene diene monomer (EPDM) roj hmab, thiab silicone roj hmab, yog siv dav hauv kev ua haujlwm tshwj xeeb: HNBR muaj cov roj muaj zog thiab hnav tsis kam, haum rau cov khoom siv tsheb thiab cov khoom siv hauv cov roj- muaj ib puag ncig; EPDM roj hmab muaj huab cua tsis zoo thiab kev laus ua haujlwm, muaj feem xyuam rau kev tsim kho sab nraum zoov thiab aerospace teb; silicone roj hmab tuaj yeem tiv taus qhov kub thiab txias xws li -60℃txog 250 degree, ua rau nws zoo tagnrho rau siab -kub lossis qis-kub precision khoom. Tsis tas li ntawd, cov khoom ntxiv xws li vulcanizing agents, anti-aging agents, and reinforcing agents are added thaum lub sij hawm npaj cov khoom los txhim kho cov kav ntev, lub zog, thiab kev ua haujlwm ruaj khov ntawm cov khoom.
Cov txheej txheem tsim cov roj hmab buffers thiab dampers yog qhov nyuaj, nrog rau cov khoom sib xyaw, molding, vulcanization, thiab tom qab- ua. Kev sib xyaw cov khoom yog thawj kauj ruam tseem ceeb: cov khoom siv roj hmab thiab cov khoom siv ntxiv yog sib xyaw rau hauv ib qho kev faib ua feem uas siv cov khoom sib tov los ua cov roj hmab sib xyaw ua ke, uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom kawg. Moulding koom nrog nias cov roj hmab sib xyaw rau hauv cov duab uas xav tau siv cov pwm, nrog pwm tsim txiav txim siab cov khoom tsim thiab qhov tseeb qhov tseeb. Vulcanization yog cov txheej txheem tseem ceeb, qhov twg cov roj hmab molded yog rhuab thiab nias kom ua rau muaj tshuaj lom neeg, hloov cov roj hmab sib txuas rau hauv ib qho ntoo khaub lig- txuas cov khoom elastic nrog kev ua haujlwm ruaj khov. Post- kev ua tiav suav nrog kev txiav, polishing, thiab kev ntsuas kev ua haujlwm kom tshem tawm cov burrs, kho qhov ntev, thiab xyuas kom cov khoom ua tau raws li cov qauv kev. Advanced manufacturing technologies xws li precision molding thiab ntse vulcanization tau maj mam saws nyob rau hauv kev lag luam los txhim kho ntau lawm efficiency thiab cov khoom sib xws.
Daim ntawv thov teb ntawm cov roj hmab buffers thiab dampers yog qhov dav, npog yuav luag txhua qhov kev lag luam loj uas xav tau kev poob siab thiab kev co tswj. Hauv kev lag luam tsheb, lawv tau siv rau hauv chassis systems, engines, thiab ncua kev kawm ntawv los txo kev co ntawm lub cav thiab txoj kev nto, txhim kho kev nplij siab, thiab tiv thaiv lub tsheb Cheebtsam -tshwj xeeb tshaj yog nyob rau hauv lub zog tshiab tsheb (NEVs), qhov twg siab - roj hmab dampers yog nyob rau hauv siab thov kom txo tau kev co los ntawm hluav taws xob motors. Hauv kev lag luam aerospace thiab tiv thaiv kev lag luam, lawv tau siv rau hauv cov tshuab dav hlau, cov tshuab foob pob hluav taws xob, thiab lub dav hlau los tiv thaiv kev cuam tshuam thiab kev vibrations, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov cuab yeej siv thaum ua haujlwm. Hauv kev tsim kho kev lag luam, lawv tau siv rau hauv cov txuas hniav, cov tsev siab - nce siab, thiab cov tshuab tsim kho kom txo qis kev vibration los ntawm cua, av qeeg, thiab kev siv tshuab, tiv thaiv lub tsev thiab txhim kho kev nyab xeeb ntawm kev tsim kho.
Tsis tas li ntawd, roj hmab buffers thiab dampers yog dav siv nyob rau hauv mechanical engineering, electronics, khoom siv kho mob, thiab lwm yam. Hauv cov cuab yeej siv tshuab, lawv tau nruab rau hauv cov twj tso kua mis, lub cev muaj zog, thiab compressors kom txo qis kev vibration thiab suab nrov, txuas ntxiv cov khoom siv lub neej. Hauv cov khoom siv hluav taws xob, xws li cov cuab yeej precision thiab 5G cov khoom siv sib txuas lus, lawv muab kev co kev sib cais los tiv thaiv cov khoom rhiab los ntawm kev cuam tshuam sab nraud. Hauv cov khoom siv kho mob, kev kho mob - qib roj hmab dampers yog siv hauv MRI cov tshuab thiab cov cuab yeej phais kom ua haujlwm ruaj khov thiab txhim kho kev kho mob kom raug.
