Sankhani chilankhulo Kukhala ndi moyo wautali wa zomangamanga zamakono-kuchokera ku zida zamlengalenga zothamanga kwambiri kupita ku makina opangira mafakitale akuluakulu-kumakhala pangozi nthawi zonse ndi mphamvu yosaoneka ya kugwedezeka kwa makina. Chinthu chikavutitsidwa mobwerezabwereza, ming'alu yaing'ono imayamba kupangika, ndipo pamapeto pake imatsogolera ku kulephera kwadongosolo, zomwe zimatchedwa kutopa. Kuti athane ndi izi, sayansi ya zida zasintha kupitilira ma aloyi osavuta kuti agwirizane ndi sayansi yaukadaulo yaukadaulo. sangweji yapamwamba kwambiri ya viscoelastic . Kaphatikizidwe kapadera kameneka kamakhala ngati njira yoyamba yodzitetezera, yomwe imayamwa mphamvu ya kinetic yomwe ingagwetse kamangidwe kake ndi mkati.
Physics of Energy Dissipation mu High-Damping Viscoelastic Sandwich Material
Pachimake pachitetezo chadongosolo pali mawonekedwe apadera a ma cell a viscoelasticity. Mosiyana ndi zida zotanuka zomwe zimasunga ndikubwezeretsa mphamvu (monga kasupe) kapena zinthu zowoneka bwino zomwe zimayenda mopsinjika (monga uchi), sangweji yapamwamba kwambiri ya viscoelastic ali ndi "memory" yomwe imalola kuti iwononge mphamvu ngati kutentha. Chigawo chomangika chikagwedezeka, gawo la viscoelastic mkati mwa sangweji limakhala ndi vuto la shear. Chifukwa cha kapangidwe kake ka mamolekyu, maunyolo a polima amasunthikana, zomwe zimapangitsa kuti pakhale kukangana mkati.
Kukangana kwamkati kumeneku ndiko chinsinsi chochepetsera kutopa. Mwa kutembenuza mphamvu yamakina yakugwedezeka kukhala yocheperako yamphamvu yotenthetsera, zinthu zasangweji zimalepheretsa nsonga za resonant. M'zinthu zachikhalidwe za monolithic, nsongazi zimakulitsa kupsinjika pafupipafupi, ndikufulumizitsa "kuuma kwa ntchito" ndikusweka kwachitsulo. Kuphatikizika kwa phata la viscoelastic kumatsimikizira kuti mphamvuyo "imachotsedwa" isanafike pamlingo wovuta, ndikuteteza bwino zikopa zamapangidwe kuchokera ku mphamvu zowononga za resonance.
Kufalitsa Katundu Wowonjezera kudzera pa Structural Composite Vibration Damping Plate
M'ntchito zolemetsa monga ziboliboli zam'madzi kapena zothandizira mlatho wanjanji, kuyimitsa sikungakhale kongoganizira; iyenera kukhala gawo la njira yolemetsa. Ili ndiye gawo loyambirira la structural composite vibration damping plate . Ma mbale awa amapangidwa kuti azikhala okhazikika komanso olimba kwambiri pomwe akupereka zonyowa zamkati. Mwa kuluka ulusi wamphamvu kwambiri—monga carbon kapena aramid—m’matrix omwe amaphatikizapo utomoni wonyowa, akatswiri amapanga zinthu zomwe zimakhala chishango komanso chigoba.
The structural composite vibration damping plate amagwira ntchito pogawa katundu wogwedezeka kudera lonselo. M'mbale zachitsulo zokhazikika, kugwedezeka kumachitika nthawi zambiri pamalumikizidwe, zomangira, kapena zowotcherera, ndikupanga "malo otentha" pakutopa. Kuphatikizika kwa mbale zonyowa izi kumapangitsa mphamvu kuti ifalikire kudzera pa netiweki ya fiber, pomwe imalumikizidwa ndi matrix onyowa. Njira yapadziko lonse lapansi yoyendetsera mphamvu zamagetsi imatsimikizira kuti palibe mfundo imodzi yokhayo yomwe imakhudzidwa ndi zovuta zamakina, kukulitsa kwambiri nthawi pakati pa kukonza ndikuchepetsa mtengo wa umwini wazinthu zazikuluzikulu.
Precision Isolation kudzera pa Multilayer High-Damping Vibration Damper
Ngakhale mbale zazikuluzikulu zimanyamula katundu wopangidwa, makina olondola amafunikira njira yokhazikika yodzipatula. The multilayer high-damping vibration damper ndi njira yophatikizika, yogwira ntchito kwambiri yopangidwa kuti ipangike kuti ikhale yolimba kwambiri kuchokera pamaphokoso othamanga kwambiri ndi jitter. Ma dampers awa amagwiritsidwa ntchito mobwerezabwereza mu makampani a semiconductor, kujambula kwachipatala, ndi zida zomvera zomvera kwambiri, kumene ngakhale micron yosuntha ingayambitse kutayika kwa deta kapena zolakwika zamakina.
A multilayer high-damping vibration damper imagwira ntchito pa mfundo ya impedance mismatching. Posanjikiza zigawo za kachulukidwe kosiyanasiyana ndi ma elasticity, damper imapanga njira yovuta kuti ma vibrate aziyenda. Pamene mafunde ogwedezeka akuyenda m'magawo, ayenera kudutsa njira zingapo, zomwe zimapangidwira kuti ziwonetsere gawo la mphamvu kumbuyo kapena kuyamwa kupyolera mu shear ya viscoelastic. "Labyrinth" iyi ya mphamvu ya kinetic imawonetsetsa kuti mbali yotulutsa damper imakhala chete, kuteteza timagulu tating'ono ting'onoting'ono kuti tisagwedezeke chifukwa cha kugwedezeka kwa mafani ozizira, ma mota, kapena zinthu zakunja zachilengedwe.
Chitetezo Chokhazikika cha Multi-layer High Damping Shockproof Zothetsera
M'malo ovuta kwambiri - monga magalimoto ankhondo opanda msewu kapena magalimoto oyendetsa ndege - kugwedezeka nthawi zambiri kumatsagana ndi kugwedezeka kwadzidzidzi, kowopsa. Zipangizo zonyowa nthawi zambiri "zimakhala pansi" pazochitika zodzidzimutsa, zomwe zimasiya kugwira ntchito nthawi yomwe zikufunika kwambiri. Apa ndi pamene Mipikisano wosanjikiza mkulu damping shockproof mayankho amatsimikizira kufunika kwake. Machitidwewa adapangidwa kuti akhale "opanda mzere," kutanthauza kuti kukana kwawo kumawonjezeka pamene mphamvu ya mphamvu ikukula.
"Shockproof" mbali ya a Mipikisano wosanjikiza mkulu damping shockproof Kusonkhana kumatheka chifukwa cha kusanjika kwa thovu zofewa, zotengera mphamvu komanso zolimba, zonyamula katundu. Panthawi yogwira ntchito bwino, zigawo zofewa zimayang'anira kugwedezeka kwapansi kuti ateteze kutopa kwanthawi yayitali. Pazochitika zowopsya, zigawo zolimba zimagwira ntchito kuti zisawonongeke kuti zisawononge malire ake. Chitetezo chamitundu yambirichi chimatsimikizira kuti kapangidwe kake kamakhalabe ndi mphamvu yanthawi yomweyo komanso kulepheretsa "kulira" kwanthawi yayitali komwe kumatsatira kugwedezeka, komwe nthawi zambiri kumathandizira kubisala kutopa kwamagetsi pamagetsi ndi ma airframe.
Multilayer High-Damping Vibration Damper : Zamtsogolo Zamtsogolo mu Viscoelastic Material Science
Chisinthiko cha sangweji yapamwamba kwambiri ya viscoelastic ikupita ku gawo la "zochita" ndi "zanzeru" zophatikiza. Ofufuza pakali pano akufufuza kuphatikizika kwa ulusi wa piezoelectric mu structural composite vibration damping plate . Ulusiwu ukhoza kupanga magetsi opunduka ndi kugwedezeka, komwe kumatha kugwiritsidwa ntchito kupatsa mphamvu masensa omwe amawunika momwe zinthu zilili munthawi yeniyeni. Izi zimapanga dongosolo la "kudzifufuza" lomwe lingathe kuchenjeza mainjiniya za kuyamba kwa kutopa kusanawonekere ndi maso.
Kuphatikiza apo, kukhudzidwa kwachilengedwe kwazinthuzi ndikukulitsa chidwi chamakampani. M'badwo wotsatira wa multilayer high-damping vibration damper ikupangidwa pogwiritsa ntchito ma polima obwezerezedwanso ndi ma resin opangidwa ndi bio omwe amapereka magwiridwe antchito a viscoelastic popanda kaboni wazinthu zachikhalidwe zochokera kumafuta. Poyenga mamolekyu a geometry azinthu zokhazikikazi, opanga akukwaniritsa zocheperako zocheperako pomwe akugwiritsa ntchito misala yocheperako, zomwe zikuthandizira kukakamiza kwapadziko lonse lapansi kuti apange uinjiniya wopepuka, wopanda mphamvu.
Utali wautali wa zomangamanga zamakono-kuchokera ku zida zamlengalenga zothamanga kwambiri kupita ku makina opangira makina akuluakulu a mafakitale-kumakhala pangozi nthawi zonse ndi mphamvu yosaoneka ya kugwedezeka kwa makina.
