G iyuniti inowanzoshandiswa kutsanangura amplitude yevibration mumota dzekudederauye ma "linear resonant actuators". Inomiririra kukurumidza kunokonzerwa negiravhiti, iyo inosvika mamita 9.8 pasekondi imwe neimwe yakaenzana ne "square metres" (m/s²).
Kana tichiti huwandu hwe vibration hwe1G, zvinoreva kuti vibration amplitude yakaenzana nekumhanya kunoitika chinhu nekuda kwegravity. Kuenzanisa uku kunotibvumira kunzwisisa simba re vibration uye kukanganisa kwayo pahurongwa huripo kana mashandisirwo ahwo.
Zvakakosha kuziva kuti G ingori nzira yekuratidza amplitude yevibration, inogonawo kuyerwa mune mamwe mayuniti akadai semamita pasekondi imwe chete (m/s²) kana mamilimita pasekondi imwe chete (mm/s²), zvichienderana nezvinodiwa kana mwero chaiwo. Kunyange zvakadaro, kushandisa G seyuniti kunopa nzvimbo yakajeka yekutarisa uye kunobatsira vatengi kunzwisisa mazinga evibration nenzira yakakodzera.
Chii chiri chikonzero chekusashandisa displacement (mm) kana force (N) senzira yekuyera vibration amplitude?
Mota dzekudengenyekaKazhinji hadzishandiswi dzoga. Dzinowanzo batanidzwa mumasisitimu makuru pamwe chete nematargets masses. Kuti tiyere vibration amplitude, tinoisa mota patarget mass inozivikanwa uye tinoshandisa accelerometer kuunganidza data. Izvi zvinotipa mufananidzo wakajeka wehunhu hwevibration hwesystem, hwatinoratidza mudhayagiramu yehunhu hwekushanda.
Simba rinoitwa nemota inodedera rinotsanangurwa ne equation inotevera:
$$F = m \times r \times \omega ^{2}$$
(F) inomiririra simba, (m) inomiririra huremu hwehuremu husina kusimba pamota (pasinei nehurongwa hwese), (r) inomiririra huremu husina kusimba hwehuremu husina kusimba, uye (Ω) inomiririra frequency.
Zvinofanira kucherechedzwa kuti simba rekudzungudza remota chete ndiro rinoregeredza simba rehuremu hwaro. Semuenzaniso, chinhu chinorema chinoda simba guru kuti chibudise mwero wakafanana wekukurumidzira sechinhu chidiki uye chakareruka. Saka kana zvinhu zviviri zvikashandisa mota imwe chete, chinhu chinorema chichadengenyeka kusvika padanho diki, kunyangwe mota dzichiburitsa simba rimwe chete.
Chimwe chikamu chemota iyi vibration frequency:
$$ f = \frac{Motor \: Kumhanya \:(RPM)}{60}$$
Kufamba kunokonzerwa nekudedera kunokanganiswa zvakananga nekuwanda kwekudedera. Mumudziyo unodedera, masimba anoshanda achitenderera pane sisitimu. Pasimba rega rega rinoshandiswa, pane simba rakaenzana uye rakapesana rinozopedzisira radzima. Kana kuwanda kwekudedera kwakakwira, nguva iri pakati pekuitika kwemasimba anopikisana inoderera.
Saka, hurongwa hwacho hune nguva shoma yekubviswa simba risati rabviswa simba. Pamusoro pezvo, chinhu chinorema chichava nekuchinja kudiki pane chinhu chakareruka kana chikashandiswa nesimba rimwe chete. Izvi zvakafanana nemhedzisiro yambotaurwa pamusoro pesimba. Chinhu chinorema chinoda simba rakawanda kuti chiwane kuchinja kwakafanana nechinhu chakareruka.

Chikwata chedu chinogona kupa rutsigiro nerubatsiromota yekudedera yemagetsizvigadzirwa. Tinonzwisisa kuti kunzwisisa, kutsanangura, kusimbisa uye kubatanidza zvigadzirwa zvemota mumashandisirwo ekupedzisira kunogona kuoma. Tine ruzivo nehunyanzvi hwekubatsira kuderedza njodzi dzine chekuita nekugadzirwa kwemota, kugadzirwa kwayo uye kuwanikwa kwayo. Bata timu yedu nhasi kuti mukurukure zvaunoda zvine chekuita nemota uye uwane mhinduro inokodzera zvaunoda. Tiri pano kuti tikubatsire.
