Sayansi Yachilengedwe ya Vibration Damping Plate

Pamtima pazamankhwala amayimbidwe amagalimoto pali vuto la structural resonance. Galimoto ndi gulu lophatikizika kwambiri la zitsulo zopyapyala zomwe, zikakhudzidwa ndi injini kapena kukhudzidwa kwa msewu, zimakhala ngati khungu la ng'oma. Pofuna kuthana ndi izi, kukhazikitsa kwa a kugwedera damping mbale ndi sitepe yoyamba komanso yovuta kwambiri. Mambale amenewa si zotchinga chabe; iwo ndi otembenuza mphamvu. s

A wapamwamba kwambiri kugwedera damping mbale nthawi zambiri amagwiritsa ntchito mphira wonyezimira wa visco-elastic, nthawi zambiri mphira wapadera wa butyl, womangidwa ndi aluminiyamu wosanjikiza. Pamene zitsulo za galimoto ziyesa kugwedezeka, mbale yonyowa imasuntha nayo. Kukangana kwamkati mkati mwa visco-elastic layer kumasintha mphamvu ya kinetic kukhala kutentha kocheperako, "kunyowetsa" kugwedezeka kusanatuluke ngati phokoso lomveka. Njirayi, yomwe imadziwika kuti "damping," imasintha ma frequency a resonant a gululo, ndikuisintha kuchokera ku "clang" yolimba, yachitsulo kupita ku phokoso lopanda phokoso. Mwa kuyika mbalezi pamalo akulu, athyathyathya ngati zikopa za zitseko ndi zowawa zapansi, munthu akhoza kukhazikika bwino pamafelemu agalimoto.

Kupeza Chitonthozo Chamkati Kupyolera mu Car Sound Deadening         

Kupitilira kuyang'anira kugwedezeka kwachitsulo chokha, cholinga chachikulu cha kutsitsa phokoso lagalimoto ndi kupanga comprehensive acoustic envelopu. Izi zimaphatikizapo njira yamitundu yambiri yomwe imalimbana ndi phokoso lamitundu yosiyanasiyana: phokoso lopangidwa ndi kapangidwe kake (kugwedezeka komwe kumadutsa pa chassis) ndi phokoso landege (mphepo, phokoso la matayala, ndi magalimoto odutsa).

Ndondomeko ya kutsitsa phokoso lagalimoto pamafunika kuyandikira mosamala mkati mwagalimoto. Zimayamba ndi kuvula kanyumbako—kuchotsa mipando, makapeti, ndi makadi a pakhomo—kuti asonyeze chigoba chopanda kanthu cha makinawo. Kugwiritsa ntchito zotsekera m'malo obisikawa kumapanga malo opanda phokoso. Mwachitsanzo, kuchiza denga lagalimoto kumatha kuchepetsa kwambiri "kugunda" pamvula yamphamvu, pomwe kuwongolera magudumu kumatha kuchepetsa kumveka kwa matayala pa phula.

Njira yonseyi imachita zambiri osati kungokhazika mtima pansi; imakulitsa magwiridwe antchito amtundu wamtundu wagalimoto. M'galimoto yosasamalidwa, oyankhula ayenera kupikisana ndi phokoso lapamwamba, lomwe nthawi zambiri limapangitsa kuti pakhale matope amatope ndi ma toni opotoka. Pochita bwino kutsitsa phokoso lagalimoto strategy, chiŵerengero cha "signal-to-noise" chiwongoleredwa bwino, kulola kuti nyimbo ziwoneke bwino ngakhale pa liwiro la msewu waukulu.

The Industry Standard: Dynamat Sound Deadening       

M'dziko lokonzanso magalimoto ndi ma audio apamwamba, mitundu ina yakhala yofanana ndiukadaulo womwe adachita. Dynamat imamveka kufa imayimira mulingo wagolide muzowonda-wochepa kwambiri, wochita bwino kwambiri pakutsekereza kwamayimbidwe. Mbiri yake imakhazikika pa kukhazikika kwa mankhwala ake, omwe amapangidwa kuti azikhala ogwira mtima pamitundu yosiyanasiyana ya kutentha popanda kuphulika m'nyengo yozizira kapena kusungunuka m'chilimwe.

Zomwe zimakhazikitsa Dynamat imamveka kufa kupatula ndikosavuta kwake kuphatikiza. Chifukwa ndi yogwirizana kwambiri, imatha kukanikizidwa m'makola ovuta komanso m'kati mwa poto kapena thunthu lagalimoto popanda kusiya mipata ya mpweya. Mipata ya mpweya ndi mdani wa chithandizo cha ma acoustic, chifukwa amalola kupititsa patsogolo mafunde a phokoso. Chomangira chokhazikika chokhazikika chomwe chimapangidwa ndi mapepala apamwambawa chimatsimikizira kuti zinthu zowonongeka zimakhala mbali yofunika kwambiri ya galimoto, kupereka yankho losatha lomwe limakhalapo kwa moyo wa galimotoyo. Kwa ambiri otolera ndi omanga makonda, dzina la "Dynamat" ndi chizindikiro chamtundu womwe umatanthauza kuti galimoto idamangidwa ndi chidwi chofuna kutsata.

Chitetezo Chapadera ndi Anti Vibration Plate          

Ngakhale zida zambiri zamayimbidwe zidapangidwa kuti zizigwiritsidwa ntchito kwambiri, ma mbale ya anti vibration nthawi zambiri amapeza kwawo m'malo enieni opsinjika kwambiri pomwe zida zamakina zolemetsa zimakumana ndi chassis. Ma mbalewa amagwiritsidwa ntchito pafupipafupi m'dera la firewOnse kapena kuzungulira njira yopatsirana, komwe kutentha ndi mphamvu zamakina zimakhala zamphamvu kwambiri.

The mbale ya anti vibration imapangidwa kukhala chitetezo champhamvu. Mosiyana ndi mafilimu opepuka, mbalezi nthawi zambiri zimakhala zokhuthala ndipo zimatha kukhala ndi masitepe angapo kuti zithetse kusokonezeka kwapang'onopang'ono komwe zida zopepuka zimatha kuphonya. Udindo wawo ndi wofunikira kwambiri pamagalimoto a dizilo kapena magalimoto ochita masewera olimbitsa thupi okhala ndi injini zolimba, pomwe mawotchi "rumble" amakhalapo nthawi zonse. Pochotsa kanyumba kuchokera ku injini ya injini pogwiritsa ntchito mbale ya anti vibration , wopanga akhoza kusunga kuuma kwapangidwe kwa galimoto pamene akupatula okwera ku zovuta zamphamvu za powertrain.

Kudzipatula Kwathunthu ndi Mapepala Oletsa Kugwedezeka Kwapamwamba         

Pamalo ovuta kwambiri omvera - monga ma limousine apamwamba kapena masitudiyo ojambulira m'manja - kutayira kokhazikika nthawi zambiri kumawonjezeredwa ndi mkulu kachulukidwe odana kugwedera pepala . Pamene mbale zonyowa zimayang'ana kuletsa zitsulo kuti zisagwedezeke, mapepala olemera kwambiriwa amakhala ngati "chotchinga chodzaza" kuti atseke mafunde a phokoso kuti asadutse pansi ndi pamoto.

A mkulu kachulukidwe odana kugwedera pepala nthawi zambiri imakhala yolemera kwambiri kuposa zida zonyowa. Unyinji uwu ndi wofunikira chifukwa, m'dziko la ma acoustics, kulemera ndi mdani wamkulu wa kufalitsa mawu. Mapepalawa nthawi zambiri amagwiritsidwa ntchito ngati gawo lachiwiri, loyikidwa pamwamba pa zinthu zonyowa kuti apange "sandwich" zotsatira. Kuphatikizikaku ndikothandiza kwambiri kutsekereza mkokomo wapamsewu wocheperako womwe umadziwika ndi maulendo ataliatali. Chifukwa mapepalawa ndi owundana, amaperekanso kutsekemera kwa kutentha, kusunga kanyumba kozizira m'chilimwe komanso kutentha m'nyengo yozizira, kumapangitsanso chitonthozo cha omwe alimo.

Tsamba la Anti-Vibration : Kugwirizana kwa Fomu ndi Ntchito      

Sayansi yakukhala chete mu dziko la magalimoto ndi umboni wa kupita patsogolo kwa uinjiniya wa zinthu. Kuchokera paudindo woyambira wa kugwedera damping mbale poweta khungu lachitsulo la galimoto ku chitetezo cholemera kwambiri cha a mkulu kachulukidwe odana kugwedera pepala , zida izi zimagwira ntchito limodzi kuti zifotokozenso ubale wathu ndi msewu. Kaya munthu akugwiritsa ntchito kudalirika kotsimikizika kwa Dynamat imamveka kufa kapena kuyamba mwambo kutsitsa phokoso lagalimoto pulojekitiyi, zotsatira zake zimakhala galimoto yomwe imakhala yolimba kwambiri, yapamwamba kwambiri, komanso yamtendere kwambiri. Pamene tikuyandikira nthawi ya magalimoto amagetsi, kumene mphepo ndi phokoso la msewu zimakhala zomveka kwambiri, kufunikira kwa zotchinga zapaderazi zotsutsana ndi kugwedezeka ndi phokoso zidzangopitirira kukula.

Pamtima pazamankhwala amayimbidwe amagalimoto pali vuto la structural resonance.
