Tshiab breakthrough nyob rau hauv ultrasonic lub cev tshuab hauv Suav teb
Ultrasonic motors yog ib lub tswvyim tshiab ntawm cov tshuab hluav taws xob uas tsim tau sai heev rau xyoo 1980s. Nws yog lub ntsiab ntawm txoj kev loj hlob thiab kev sib txuas ntawm kev ua kom muaj zog thiab yoj science, cov ntaub ntawv tshawb fawb, hluav taws xob hluav taws xob, kev tswj tsis tau thiab kev tswj hwm super-precision. Nws lov los ntawm lub tswv yim ntawm cov tsoos pob zeb, muaj kev sib raug zoo ntawm electromagnetic, tsis muaj suab nrov, thiab tuaj yeem nqus tau. Ua hauj lwm hauv siab thiab tsis muaj peevxwm, qhov sib txawv ntawm ntau yam, thiab qhov ua tau zoo tsis tsawg dua li qhov txo qis.
Qhov tseem ceeb cov teeb meem uas yuav tsum tau daws nyob rau hauv lub industrialization ntawm ultrasonic motor technology hauv Suav teb: cov kev siv technology ntawm piezoelectric cov ntaub ntawv; cov yam ntxwv nonlinear ntawm ultrasonic motors; cov cuab yeej siv tshuab ultrasonic motors. Qhov project no yog ib qho kev tshawb fawb ntawm kev tsim tshuab. Lub cav TRUM-60 ultrasonic yog ib lub cav ncig teb sab ultrasonic lub cav, thiab ib qho kev txhawb nqa ib leeg kev txhawb siab ntxiv cov lus qhia.
Tus menyuam yaus hla hom ultrasonic lub cev muaj zog hu ua ultrasonic motor (USM). Nws yog qhov ntxov tshaj plaws ntawm ultrasonic lub cev muaj zog, feem ntau paub tab siv tshuab, thiab industrialization thiab engineering application kuj muaj kev vam meej. Txij li thaum zaus ntawm stator kev co tshaj 20 kHz, uas belongs rau ultrasonic zaus qhab, nws yog feem ntau hu ua ultrasonic lub cev muaj zog los yog ultrasonic lub cev. Vim nws tus tshwj xeeb txojcai thiab cov qauv, ultrasonic lub cev muaj ntau yam koj tus qauv piv nrog electromagnetic lub cev, xws li: tsis muaj magnetic field cuam, self-locking fais fab tuag, ceev teb, loj thrust / luj piv, cov qauv yooj yim, . Yog li, raws li tus actuator ntawm lub kaw lus tswj muaj ib tug dav daim ntawv thov, tau ua ntawv thov kom precision positioning thiab lwm yam. Txawm li cas los xij, nrog txoj kev tsim cov cuab yeej siv high technology, daim ntawv tso npe ua rau cov lus tshaj tawm rau kev tswj xyuas qhov kev txiav txim siab. Kev txhim kho ceev ceev yog ib qho tsim nyog rau tus ultrasonic lub cev kom dav siv nyob rau hauv lub precision tswj system.
Qhov ceev stability ntawm cov hneev hnyav hom ultrasonic lub cev muaj zog ntsig txog kev sib tiv tauj nruab nrab ntawm tus stator thiab cov rotor. Luam tawm hauv "Phau Ntawv Xov Xwm Hluav Taws Xob Engineering", Lub Kaum Hlis 29, 2011, "Txoj Kev Kawm Tshaj Tawm Ntawm Kev Tshaj Tawm Ntawm Kev Xiam Hloov Ultrasonic Motors", ib txoj hauv kev txhim kho kev ruaj ntseg ntawm kev ua qauv zoo tsim tawm.
Nyob rau hauv thiaj li yuav txhim kho qhov kev ceev ceev ntawm cov npav hla mus tom qab xa ultrasonic lub cav, daim ntawv ntsuas cov cawv ntawm kev ua haujlwm thiab sib dhos yuam kev ntawm kev ruaj ntseg ceev nyob rau hauv cov kev pab uas twb muaj ob kab uas twb muaj lawm. Nws pom tau tias qhov tsis siab sib xws ntawm qhov tsis sib haum xeeb yog ib qho tseem ceeb ntawm kev ua kom muaj kev vam meej. Ib qho kev txhawb nqa ib qho kev txhawb siab kom siab dua ntxiv yog npaj siab kom ncav qhov ntsuas tus kheej ntawm kev sib tiv tauj. Theoretical and experimental analysis qhia tau hais tias cov tshuaj no ua rau lub siab tis ntawm tus xov tooj sib kov ntau dua thiab qhov kev nyab xeeb tshaj tawm zoo dua qub. Piv nrog rau tus thawj qauv, kev tshwm sim qhia tau tias tus ultrasonic lub cav tsis muaj tus nqi khiav dej num khiav tawm yog txo los ntawm kwv yees li 40.0% thiab cov kab sib txawv ntawm qhov sib txawv yog tsawg dua 2.0% nyob rau hauv cov xwm txheej qhov kev ua tau zoo xws li cov zis thiab qhov ceev ntawm ultrasonic lub cev muaj zog tib yam.
Yuav kom tau ib lub foothold hauv lub tshuab fais fab ultrasonic, cov pabcuam ntawm Tsoomfwv Zhao Yusheng ntawm Nanjing University of Aeronautics thiab Astronautics tau tsim nws tus kheej Wama Ultrasonic Tsav Lag Luam, uas tau tsim ib qhov chaw zoo rau kev hloov cov kev tshawb fawb tau zoo tshaj plaws rau kev tsim tau.
