G ndi gawo lomwe limagwiritsidwa ntchito kufotokozera kukula kwa kugwedezeka mkativibration motorsndi ma linear resonant actuators. Zimayimira mathamangitsidwe chifukwa cha mphamvu yokoka, yomwe ili pafupifupi mamita 9.8 pa sekondi imodzi (m/s²).
Tikamanena mulingo wa vibration wa 1G, zikutanthauza kuti kugwedezeka kwake kumafanana ndi kuthamanga kwa chinthu chifukwa cha mphamvu yokoka. Kuyerekeza uku kumatithandiza kumvetsetsa kukula kwa kugwedezeka ndi mphamvu zake zomwe zingakhudze dongosolo lamakono kapena ntchito.
Ndikofunikira kudziwa kuti G ndi njira yowonetsera kugwedezeka kwamphamvu, imathanso kuyezedwa m'mayunitsi ena monga mita pa sekondi imodzi (m/s²) kapena mamilimita pa sekondi imodzi (mm/s²), kutengera zofunika kapena muyezo. Komabe, kugwiritsa ntchito G monga gawo kumapereka malo omveka bwino komanso kumathandiza makasitomala kumvetsetsa milingo ya kugwedezeka m'njira yoyenera.
Chifukwa chiyani osagwiritsa ntchito kusamuka (mm) kapena mphamvu (N) ngati muyeso wa kugwedezeka kwamphamvu?
Vibration motorsnthawi zambiri sagwiritsidwa ntchito payekha. Nthawi zambiri amaphatikizidwa m'machitidwe akuluakulu pamodzi ndi magulu omwe amawatsata. Kuti tiyeze kukula kwa kugwedezeka, timayika injini pamtundu womwe tikudziwa ndikugwiritsa ntchito accelerometer kusonkhanitsa deta. Izi zimatipatsa chithunzi chomveka bwino cha kugwedezeka kwadongosolo lonselo, zomwe timaziwonetsa muzithunzi zofananira za magwiridwe antchito.
Mphamvu yoyendetsedwa ndi injini yogwedezeka imatsimikiziridwa ndi equation yotsatirayi:
$$F = m \nthawi r \nthawi \omega ^{2}$$
(F) imayimira mphamvu, (m) imayimira kuchuluka kwa eccentric mass pa mota (mosasamala kanthu za dongosolo lonse), (r) imayimira eccentricity ya eccentric mass, ndipo (Ω) imayimira ma frequency.
Tikumbukenso kuti kugwedera mphamvu ya galimoto yekha kunyalanyaza chikoka chandamale misa. Mwachitsanzo, chinthu cholemera kwambiri chimafuna mphamvu yaikulu kuti ipange msinkhu wofanana ndi chinthu chaching'ono ndi chopepuka. Choncho ngati zinthu ziwiri zimagwiritsa ntchito injini imodzi, chinthu cholemeracho chimagwedezeka mpaka kufika pamtunda wochepa kwambiri, ngakhale kuti ma motors amatulutsa mphamvu yomweyo.
Mbali ina ya injini ndi ma frequency a vibration:
$$ f = \frac{Motor \: Liwiro \:(RPM)}{60}$$
Kusuntha komwe kumachitika chifukwa cha kugwedezeka kumakhudzidwa mwachindunji ndi kuchuluka kwa kugwedezeka. Mu chipangizo chogwedezeka, mphamvu zimagwira ntchito mozungulira padongosolo. Pa mphamvu iliyonse yoperekedwa, pali mphamvu yofanana ndi yosiyana yomwe imathetsa. Pamene kugwedezeka kwafupipafupi kuli kwakukulu, nthawi yapakati pa zochitika za mphamvu zotsutsana imachepa.
Chifukwa chake, dongosololi limakhala ndi nthawi yochepa yoti lichotsedwe mphamvu zotsutsa zisanathe. Kuonjezera apo, chinthu cholemera kwambiri chimakhala ndi chosuntha chaching'ono kusiyana ndi chinthu chopepuka chikagwidwa ndi mphamvu yomweyo. Zimenezi n’zofanana ndi zimene tatchula poyamba paja pa nkhani ya mphamvu. Chinthu cholemera chimafuna mphamvu zambiri kuti chikwanitse kusamutsidwa mofanana ndi chinthu chopepuka.
Lumikizanani nafe
Gulu lathu likhoza kupereka chithandizo ndi chithandizo ndielectric vibration motormankhwala. Timamvetsetsa kuti kumvetsetsa, kutsimikizira, kutsimikizira ndi kuphatikiza zinthu zamagalimoto muzomaliza kumatha kukhala kovuta. Tili ndi chidziwitso ndi ukadaulo wothandiza kuchepetsa zoopsa zomwe zimagwirizanitsidwa ndi kapangidwe ka magalimoto, kupanga ndi kupereka. Lumikizanani ndi gulu lathu lero kuti mukambirane zosowa zanu zokhudzana ndi mota ndikupeza yankho lomwe likugwirizana ndi zomwe mukufuna. Tabwera kudzathandiza.
Funsani Akatswiri Atsogolereni Anu
Timakuthandizani kupewa misampha kuti mupereke mtunduwo ndikuyamikira chosowa chanu cha micro brushless motor, panthawi yake komanso pa bajeti.
