G yiyunithi edla ngokusetyenziswa ukuchaza iamplitude yokungcangcazela ngaphakathiiinjini zokungcangcazelakunye ne-linear resonant actuator. Imele isantya ngenxa yomxhuzulane, omalunga ne-9.8 yeemitha ngesekondi yesikweri (m/s²).
Xa sisithi inqanaba lokungcangcazela kwe-1G, oko kuthetha ukuba i-amplitude ye-vibration ilingana nokukhawuleziswa kwento eyenzeka ngenxa yomxhuzulane. Olu thelekiso lusivumela ukuba siqonde ubunzulu bentshukumo kunye nefuthe elinokubakho kwinkqubo yangoku okanye isicelo.
Kubalulekile ukuqaphela ukuba i-G yindlela nje yokubonakalisa i-amplitude ye-vibration, inokulinganiswa kwezinye iiyunithi ezinjengeemitha ngesekondi enye ephindwe kabini (m/s²) okanye iimilimitha ngesekondi enye (mm/s²), ngokuxhomekeke iimfuno ezithile okanye umgangatho. Nangona kunjalo, ukusebenzisa i-G njengeyunithi inika indawo ecacileyo yereferensi kwaye inceda abathengi baqonde amanqanaba okungcangcazela ngendlela efanelekileyo.
Sisiphi isizathu sokungasebenzisi i-displacement (mm) okanye amandla (N) njengomlinganiselo we-vibration amplitude?
Iinjini zokungcangcazelaazisetyenziswa zodwa. Zihlala zidityaniswa kwiinkqubo ezinkulu kunye nobuninzi ekujoliswe kubo. Ukulinganisa i-vibration amplitude, sifaka i-motor kubunzima obujoliswe kuyo kwaye sisebenzise i-accelerometer ukuqokelela idatha. Oku kusinika umfanekiso ocacileyo weempawu zokungcangcazela zizonke zenkqubo, esithi ke siyibonise kumzobo weempawu zokusebenza eziqhelekileyo.
Amandla asetyenziswa yinjini yokungcangcazela amiselwa le nxaki ilandelayo:
$$F = m \ amaxesha r \ amaxesha \ omega ^ {2} $$
(F) imele amandla, (m) imele ubunzima bobunzima be-eccentric kwi-motor (kungakhathaliseki ukuba yinkqubo yonke), (r) imele i-eccentricity ye-eccentric mass, kwaye (Ω) imele ukuphindaphinda.
Kufuneka kuqatshelwe ukuba kuphela amandla okungcangcazela kwemoto ayihoyi impembelelo yobunzima obujoliswe kuyo. Umzekelo, into enzima ifuna amandla amakhulu ukuvelisa inqanaba elifanayo lokukhawuleza njengento encinci kunye nekhaphukhaphu. Ngoko ukuba izinto ezimbini zisebenzisa i-motor enye, into enzima kakhulu iya kungcangcazela ukuya kwi-amplitude encinci kakhulu, nangona iimotor zivelisa amandla afanayo.
Omnye umba wemoto kukushukuma rhoqo:
$$ f = \ frac{Motor \: Isantya \:(RPM)}{60}$$
Ukufuduswa okubangelwa yi-vibration kuchaphazeleka ngokuthe ngqo ngokuphindaphindiweyo kwe-vibration. Kwisixhobo sokungcangcazela, amandla asebenza ngokujikelezayo kwisistim. Kuwo onke amandla asetyenziswayo, kukho amandla alinganayo nachasayo athi ekugqibeleni acime. Xa i-frequency vibration iphezulu, ixesha phakathi kokwenzeka kwemikhosi echasayo liyancipha.
Ke ngoko, inkqubo inexesha elincinci lokufuduswa phambi kokuba imikhosi echasayo iyirhoxise. Ukongeza, into enzima kakhulu iya kuba nokufuduswa okuncinci kunento elula xa iphantsi kwamandla afanayo. Oku kuyafana nomphumo okhankanywe ngaphambilana ngokuphathelele amandla. Into enzima ifuna amandla amaninzi ukufezekisa ukufuduka okufanayo njengento elula.
