Momwe mungapangire nyanga yayikulu ya akupanga - I

Osiyana kuwotcherera nyanga zimafunika zosiyanasiyana kuwotcherera zinthu, ziribe kanthu pafupi kumunda kuwotcherera kapena kufala kuwotcherera, theka lokha yoweyula kutalika akupanga nyanga kukwaniritsa pazipita matalikidwe a kuwotcherera mapeto nkhope.Akupanga nyanga , kupezeka ndi popanda matalikidwe.Akupanga pulasitiki kuwotcherera makina kupanga akupanga nyanga ntchito akupanga mfundo.

Akupanga nkhungu kapangidwe si lophweka monga maonekedwe ake, pamene ntchito molakwika kukonzedwa kapena untuned kuwotcherera nyanga, izo zidzachititsa zotayika mtengo kupanga wanu - izo kuwononga kuwotcherera zotsatira, kapena kwambiri kwambiri adzatsogolera mwachindunji kuwonongeka kwa transducer. kapena jenereta.Mapangidwe a ultrasonic nkhungu amafuna chidziwitso chapadera ndi luso lapadera - momwe mungatsimikizire kuti nyanga yowotcherera imatha kugwira ntchito mwachuma?Momwe mungawonetsere kuti nkhungu yowotcherera imatha kusamutsa kugwedezeka kwamakina komwe kumasinthidwa ndi transducer kupita ku chogwirira ntchito, mainjiniya athu adaganizira bwino ulalo uliwonse.

Kuwotcherera nyanga ndi gawo lofunika kwambiri pazitsulo zowotcherera za pulasitiki za akupanga, ndipo mapangidwe ake amagwirizana mwachindunji ndi khalidwe la kuwotcherera.Mzere wowotcherera wa mizere umagawidwa m'magulu angapo ofanana ndi kulotera koyenera, ndipo chinthu chilichonse chimatha kuwonedwa ngati nyanga yopindika.Ma frequency equation a chinthu cholumikizira chowotcherera amapezedwa ndi njira yosinthira masanjidwewo, omwe amapereka maziko ongoyerekeza pamapangidwe a cholumikizira cholumikizira.

Zotsatira zoyeserera zikuwonetsa kuti ma frequency omwe amayezedwa ndi ma frequency omwe adapangidwa ndiabwino pakuwotcherera kwa mizere yopangidwa ndi equation iyi.Njira yopangira iyi ili ndi tanthauzo lodziwikiratu, kuwerengera kosavuta komanso koyenera kwambiri pakupanga uinjiniya.Komanso, chikoka cha nambala kagawo, kagawo m'lifupi ndi kagawo kutalika pa kuwotcherera mutu kukula akhoza conveniently masamu pogwiritsa ntchito njira imeneyi, amenenso amapereka maziko ongoyerekeza kukhathamiritsa kamangidwe ka kuwotcherera nyanga.

Akupanga pulasitiki kuwotcherera zida zambiri wopangidwa akupanga mphamvu, akupanga kugwedera dongosolo ndi kuthamanga limagwirira, ndi akupanga kugwedera dongosolo wapangidwa akupanga transducer, chilimbikitso ndi kuwotcherera nyanga.Akupanga transducer ndi nyanga zambiri lakonzedwa kuti kumveka pa pafupipafupi enaake, ndipo safuna kusintha mbali zosiyanasiyana kuwotcherera, ndi kuwotcherera nyanga ayenera mwapadera anakonza molingana ndi mawonekedwe a mbali kuwotcherera.Ubwino kapena woipa wa mapangidwe ake umagwirizana mwachindunji ndi khalidwe la kuwotcherera, choncho ndi gawo lofunika kwambiri pazitsulo zowotcherera.

Pakuti mbali zazikulu kuwotcherera, iwo ayenera lalikulu kukula kuwotcherera nyanga, ndi kukula kwake nthawi zina pafupi kapena kuposa wina kotenga nthawi yoweyula yoweyula wavelength, ndiye kuwotcherera nyanga adzatulutsa kwambiri yopingasa kugwedera, chifukwa m'goli kusamutsidwa kugawa padziko cheza ake.Kuti mupeze kugawa kokhutiritsa kwa matalikidwe, njira zina, monga slotting, kung'ambika, kuwonjezera elastomer ndi kapangidwe kachiwiri, zayikidwa patsogolo.

Kugwedezeka kumayendetsedwa, komwe kutsetsereka ndi njira yomwe imagwiritsidwa ntchito kwambiri kutengera kugwedezeka kwa mfundo zowotcherera.Chifukwa chazovuta za mawonekedwewo, zimakhala zovuta kupeza njira yowunikira yolumikizira malo olumikizirana, motero njira zowerengera manambala monga njira ya Ansys zimagwiritsidwa ntchito nthawi zambiri kusanthula mavutowa.Malinga ndi maphunziro am'mbuyomu, njira yowerengera ndiyoyeneranso kukhathamiritsa kwapatsogolo kwa zolumikizira zowotcherera, ndipo alibe mwayi woyerekeza kukula ndi kuchuluka kwa zimfundo zowotcherera pamagawo oyambira.Kuti muwonetsetse zotsatira zabwinoko, ndikofunikira kulingalira kukula kwa kapangidwe kake komwe kumatha kukwaniritsa zofunikira za kapangidwe kake, chifukwa chake ndikofunikira kuphunzira chiphunzitso cha kapangidwe ka maulalo akulu akulu ndi ma grooving configuration.

Gawani poyambira pambuyo Mzere kuwotcherera mutu kugwedera kusanthula, kuwotcherera mutu akhoza kugawidwa mu mapeto unit thupi ndi pakati unit selo, ntchito zikuoneka elasticity njira ndi njira yofanana kufala mizere, kutalika kwa mayunitsi anayi osiyana amaperekedwa motero ndi mayendedwe a kuchuluka kwa ma frequency equation, ma frequency equation angagwiritsidwe ntchito kupanga mutu wautali wowotcherera, koma kapangidwe kake ndizovuta, Kusankhidwa kwa magawo ena kumadalira zomwe zachitika ndipo sikoyenera kugwiritsa ntchito uinjiniya.Mu pepalali, Mzere kuwotcherera olowa amagawidwa mu zinthu zingapo ofanana ndi slotting wololera, ndipo pafupipafupi equation wa kuwotcherera olowa chinthu akamagwira kutengerapo masanjidwewo njira, amene amapereka maziko ongoyerekeza kamangidwe ka Mzere kuwotcherera olowa.Kapangidwe kake kamakhala ndi mawerengedwe osavuta amalingaliro komanso tanthauzo lodziwikiratu, lomwe limapereka njira yosavuta komanso yotheka yopangira uinjiniya wolumikizana ndi mizere yowotcherera.
