U-G iyunithi evame ukusetshenziswa ukuchaza amplitude yokudlidliza ngaphakathivibration motorskanye nama-actuator anomugqa. Imele ukusheshisa ngenxa yamandla adonsela phansi, cishe amamitha angu-9.8 ngesekhondi yesikwele (m/s²).
Uma sithi izinga lokudlidliza le-1G, kusho ukuthi i-amplitude yokudlidliza ilingana nokusheshisa into etholwayo ngenxa yamandla adonsela phansi. Lokhu kuqhathanisa kusivumela ukuthi siqonde ukushuba kokudlidliza kanye nomthelela wako ongaba khona ohlelweni lwamanje noma uhlelo lokusebenza.
Kubalulekile ukuqaphela ukuthi u-G uyindlela nje yokuveza i-amplitude yokudlidliza, ingalinganiswa namanye amayunithi njengamamitha ngesekhondi eliyisikwele (m/s²) noma amamilimitha ngesekhondi yesikwele (mm/s²), kuye ngokuthi izidingo ezithile noma izinga. Noma kunjalo, ukusebenzisa i-G njengeyunithi kunikeza indawo eyireferensi ecacile futhi kusiza amakhasimende aqonde amazinga okudlidliza ngendlela efanele.
Siyini isizathu sokungasebenzisi i-displacement (mm) noma amandla (N) njengesilinganiso sobukhulu bokudlidliza?
Izinjini zokudlidlizangokuvamile azisetshenziswa zodwa. Avame ukufakwa ezinhlelweni ezinkulu kanye nezixuku eziqondiwe. Ukuze silinganise i-amplitude yokudlidliza, sikhweza injini kusisindo esiqondiwe esaziwayo futhi sisebenzisa i-accelerometer ukuze siqoqe idatha. Lokhu kusinika isithombe esicacile sazo zonke izici zokudlidliza zesistimu, esizosifanekisa kumdwebo wezimpawu zokusebenza ezijwayelekile.
Amandla asetshenziswa injini yokudlidliza anqunywa isibalo esilandelayo:
$$F = m \izikhathi r \izikhathi \omega ^{2}$$
(F) imele amandla, (m) imele inqwaba ye-eccentric mass motor (kungakhathalekile isistimu yonke), (r) imele ukugqama kwe-eccentric mass, futhi (Ω) imele imvamisa.
Kumele kuqashelwe ukuthi kuphela amandla okudlidliza we-motor awanaki ithonya lesisindo esiqondisiwe. Isibonelo, into enzima kakhulu idinga amandla amakhulu ukukhiqiza izinga elifanayo lokusheshisa njengento encane nelula. Ngakho uma izinto ezimbili zisebenzisa injini efanayo, into esindayo izodlidliza ibe yi-amplitude encane kakhulu, nakuba izinjini zikhiqiza amandla afanayo.
Esinye isici semoto imvamisa yokudlidliza:
$$ f = \frac{Motor \: Speed \:(RPM)}{60}$$
Ukususwa okubangelwa ukudlidliza kuthintwa ngokuqondile imvamisa yokudlidliza. Kudivayisi edlidlizayo, amandla asebenza ngokujikeleza kusistimu. Kuwo wonke amandla asetshenziswayo, kukhona amandla alinganayo naphambene agcina ewahoxisa. Uma imvamisa yokudlidliza iphakeme, isikhathi phakathi kokuvela kwamandla aphikisayo siyancipha.
Ngakho-ke, isistimu inesikhathi esincane sokususwa ngaphambi kokuba amabutho aphikisayo ayikhansele. Ukwengeza, into esindayo izoba nokugudluka okuncane kunento elula uma ingaphansi kwamandla afanayo. Lokhu kufana nomphumela okukhulunywe ngawo ekuqaleni mayelana namandla. Into esindayo idinga amandla engeziwe ukuze kuzuzwe ukugudluka okufanayo nento elula.
Xhumana nathi
Ithimba lethu linganikeza ukwesekwa nosizo ngemotor vibration kagesiimikhiqizo. Siyaqonda ukuthi ukuqonda, ukucacisa, ukuqinisekisa kanye nokuhlanganisa imikhiqizo yezimoto ezinhlelweni zokusebenza kungaba yinkimbinkimbi. Sinolwazi nobungcweti bokusiza ukwehlisa ubungozi obuhambisana nokwakhiwa kwezimoto, ukukhiqiza kanye nokuhlinzeka. Xhumana nethimba lethu namuhla ukuze uxoxe ngezidingo zakho ezihlobene nemoto futhi uthole isixazululo esifanelana nezidingo zakho ezithile. Silapha ukuzosiza.
