I-G yiyunithi esetyenziswa rhoqo ukuchaza ubukhulu bokungcangcazelaiimoto zokungcangcazelakunye nee-actuators ezihambelanayo. Imele ukukhawulezisa okubangelwa ngumxhuzulane, okumalunga neemitha ezili-9.8 ngomzuzwana osikwe (m/s²).
Xa sithi inqanaba lokungcangcazela le-1G, oko kuthetha ukuba ubukhulu bokungcangcazela bulingana nokukhawuleziswa kwento ngenxa yomxhuzulane. Olu thelekiso lusenza siqonde amandla okungcangcazela kunye nempembelelo enokubakho kwinkqubo yangoku okanye kwisicelo.
Kubalulekile ukuqaphela ukuba i-G yindlela nje yokubonisa ubukhulu bokungcangcazela, ingalinganiswa nakwezinye iiyunithi ezifana neemitha ngomzuzwana onesikwere (m/s²) okanye iimilimitha ngomzuzwana onesikwere (mm/s²), kuxhomekeke kwiimfuno ezithile okanye umgangatho. Nangona kunjalo, ukusebenzisa i-G njengeyunithi kubonelela ngendawo ecacileyo yokubhekisa kwaye kunceda abathengi baqonde amanqanaba okungcangcazela ngendlela efanelekileyo.
Yintoni isizathu sokungasebenzisi i-displacement (mm) okanye i-force (N) njengendlela yokulinganisa i-vibration amplitude?
Iimoto zokungcangcazelaazisetyenziswa zodwa. Zihlala zifakwa kwiinkqubo ezinkulu kunye nobunzima obujoliswe kuzo. Ukulinganisa ubukhulu bokungcangcazela, sifaka i-motor kwi-target mass eyaziwayo kwaye sisebenzisa i-accelerometer ukuqokelela idatha. Oku kusinika umfanekiso ocacileyo weempawu zokungcangcazela zizonke zenkqubo, esiza kuzibonisa kumzobo weempawu zokusebenza eziqhelekileyo.
Amandla asetyenziswa yimoto yokudlidliza amiselwa yile equation ilandelayo:
$$F = m \ixesha r \ixesha \omega ^{2}$$
(F) imele amandla, (m) imele ubunzima bobunzima obungaqhelekanga kwi-motor (kungakhathaliseki ukuba yinkqubo yonke), (r) imele ubungqazi bobunzima obungaqhelekanga, kwaye (Ω) imele i-frequency.
Kufuneka kuqatshelwe ukuba ngamandla okungcangcazela emoto kuphela angayinaki impembelelo yobunzima ekujoliswe kubo. Umzekelo, into enzima ifuna amandla amakhulu ukuvelisa inqanaba elifanayo lokukhawulezisa njengento encinci nekhaphukhaphu. Ngoko ke ukuba izinto ezimbini zisebenzisa imotor efanayo, into enzima iya kungcangcazela ibe yi-amplitude encinci kakhulu, nangona iimotor zivelisa amandla afanayo.
Enye into echaphazela injini kukungcangcazela rhoqo:
$$ f = \frac{Imoto \: Isantya \:(RPM)}{60}$$
Ukufuduka okubangelwa kukungcangcazela kuchatshazelwa ngokuthe ngqo kukungcangcazela rhoqo. Kwisixhobo esingcangcazelayo, amandla asebenza ngendlela ejikelezayo kwinkqubo. Kuwo onke amandla asetyenziswayo, kukho amandla alinganayo nachaseneyo ekugqibeleni arhoxisayo. Xa ukungcangcazela kuphezulu, ixesha eliphakathi kokwenzeka kwamandla achaseneyo liyancipha.
Ngoko ke, inkqubo ayinaxesha lininzi lokufuduka ngaphambi kokuba imikhosi echaseneyo iyirhoxise. Ukongeza, into enzima iya kuba nohambo oluncinci kunento elula xa iphantsi kwamandla afanayo. Oku kufana nesiphumo esikhankanyiweyo ngaphambili malunga namandla. Into enzima ifuna amandla angakumbi ukuze ifikelele ekufudukeni okufanayo nento elula.
