G ndi gawo lomwe limagwiritsidwa ntchito kwambiri pofotokoza kuchuluka kwa kugwedezeka muma motors ogwederandi ma actuator ozungulira ozungulira. Amayimira kuthamanga kwa mphamvu yokoka, komwe kuli pafupifupi mamita 9.8 pa sekondi imodzi (m/s²).
Tikanena kuti mulingo wa kugwedezeka wa 1G, zikutanthauza kuti kuchuluka kwa kugwedezeka ndikofanana ndi kuthamanga kwa chinthu chifukwa cha mphamvu yokoka. Kuyerekeza kumeneku kumatithandiza kumvetsetsa mphamvu ya kugwedezeka ndi momwe kungakhudzire dongosolo kapena ntchito yomwe ilipo.
Ndikofunika kudziwa kuti G ndi njira yongofotokozera kukula kwa kugwedezeka, imathanso kuyezedwa m'mayunitsi ena monga mamita pa sekondi imodzi yokhala ndi sikweya (m/s²) kapena mamilimita pa sekondi imodzi yokhala ndi sikweya (mm/s²), kutengera zofunikira kapena muyezo. Komabe, kugwiritsa ntchito G ngati unit kumapereka chidziwitso chomveka bwino ndipo kumathandiza makasitomala kumvetsetsa kuchuluka kwa kugwedezeka m'njira yoyenera.
Kodi chifukwa chiyani osagwiritsa ntchito displacement (mm) kapena force (N) ngati muyeso wa vibration amplitude ndi chiyani?
Ma mota ogwederaKawirikawiri sizigwiritsidwa ntchito zokha. Nthawi zambiri zimaphatikizidwa mu makina akuluakulu pamodzi ndi ma chandamale. Kuti tiyese kuchuluka kwa kugwedezeka, timayika mota pa chiwongolero chodziwika bwino ndikugwiritsa ntchito accelerometer kuti tisonkhanitse deta. Izi zimatipatsa chithunzi chomveka bwino cha mawonekedwe onse a kugwedezeka kwa makinawo, omwe tikuwonetsa mu chithunzi cha makhalidwe a magwiridwe antchito.
Mphamvu yomwe injini ya vibration imagwiritsira ntchito imatsimikiziridwa ndi equation yotsatirayi:
$$F = m \times r \times \omega ^{2}$$
(F) ikuyimira mphamvu, (m) ikuyimira kulemera kwa kulemera kosazolowereka pa mota (mosasamala kanthu za dongosolo lonse), (r) ikuyimira kusagwirizana kwa kulemera kosazolowereka, ndipo (Ω) ikuyimira mafupipafupi.
Tiyenera kudziwa kuti mphamvu yokha ya kugwedezeka kwa injini ndiyo imanyalanyaza mphamvu ya chinthu chomwe chikufunidwa. Mwachitsanzo, chinthu cholemera chimafuna mphamvu yayikulu kuti chipange liwiro lofanana ndi chinthu chaching'ono komanso chopepuka. Chifukwa chake ngati zinthu ziwiri zimagwiritsa ntchito injini yomweyo, chinthu cholemeracho chidzagwedezeka pang'ono kwambiri, ngakhale kuti injinizo zimapanga mphamvu yomweyo.
Mbali ina ya injini ndi kuchuluka kwa kugwedezeka:
$$ f = \frac{Motor \: Liwiro \:(RPM)}{60}$$
Kusuntha komwe kumachitika chifukwa cha kugwedezeka kumakhudzidwa mwachindunji ndi kuchuluka kwa kugwedezeka. Mu chipangizo chogwedezeka, mphamvu zimagwira ntchito mozungulira pa dongosolo. Pa mphamvu iliyonse yomwe imagwiritsidwa ntchito, pali mphamvu yofanana komanso yotsutsana yomwe pamapeto pake imailetsa. Pamene kuchuluka kwa kugwedezeka kuli kwakukulu, nthawi pakati pa kuchitika kwa mphamvu zotsutsana imachepa.
Chifukwa chake, dongosololi limakhala ndi nthawi yochepa yoti lisunthidwe lisanachotsedwe mphamvu zotsutsana. Kuphatikiza apo, chinthu cholemera chidzakhala ndi kusunthika kochepa kuposa chinthu chopepuka chikagwiritsidwa ntchito ndi mphamvu yomweyo. Izi zikufanana ndi momwe tafotokozera kale pankhani ya mphamvu. Chinthu cholemera chimafuna mphamvu zambiri kuti chisunthidwe mofanana ndi chinthu chopepuka.
Lumikizanani nafe
Gulu lathu likhoza kupereka chithandizo ndi chithandizo pamota yamagetsi yogwederazinthu. Tikumvetsa kuti kumvetsetsa, kufotokoza, kutsimikizira, ndi kuphatikiza zinthu zamagalimoto mu ntchito zomaliza kungakhale kovuta. Tili ndi chidziwitso ndi ukatswiri wothandiza kuchepetsa zoopsa zokhudzana ndi kapangidwe ka magalimoto, kupanga, ndi kupereka. Lumikizanani ndi gulu lathu lero kuti mukambirane zosowa zanu zokhudzana ndi magalimoto ndikupeza yankho lomwe likugwirizana ndi zosowa zanu. Tili pano kuti tikuthandizeni.
Funsani Akatswiri Anu Atsogoleri
Timakuthandizani kupewa mavuto kuti mupereke khalidwe labwino komanso kuyamikira zosowa zanu za injini yaing'ono yopanda maburashi, panthawi yake komanso pa bajeti.
