Mokhoa oa mechine

Phekolo ea botsitso ea mechine e atisa ho etsoa ha sehlahisoa se thehoa ka mor'a matšeliso le ho lokisoa ha potoloho ea sele ea mojaro le tiiso e sireletsang. Mekhoa ea mantlha ke mokhoa oa pulse fatigue, overload static pressure mokhoa le vibration ea botsofali.

(1) Mokhoa oa ho letsa mokhathala

Sele ea mojaro e kenngoa mochine oa tlhahlobo ea mokhathala o fokolang, 'me moeli o ka holimo o lekantsoe mojaro kapa 120% e lekantsoeng mojaro,' me potoloho ke makhetlo a 5,000-10,000 ka makhetlo a 3-5 ka motsotsoana. E ka lokolla ka nepo khatello e setseng ea element elastic, resistance strain gage le strain adhesive layer, mme phello ea ho ntlafatsa lintlha tsa zero le botsitso ba kutlo e hlakile haholo.

(2) Mokhoa o feteletseng oa khatello ea static

Ka khopolo, e loketse mefuta eohle ea mefuta ea ho lekanya, empa ka tlhahiso e sebetsang, aluminium alloy small-range force sensor e sebelisoa haholo.

Ts'ebetso e tjena: ka sesebelisoa se ikhethileng sa ho jara boima ba 'mele kapa sesebelisoa se bonolo sa ho roala sekoti, sebelisa 125% moroalo o lekantsoeng seleng ea mojaro bakeng sa lihora tse 4-8, kapa sebelisa 110% e lekantsoeng lihora tse 24. Mekhoa ena ka bobeli e ka finyella sepheo sa ho lokolla khatello ea maikutlo e setseng le ho ntlafatsa ntlha ea zero le botsitso ba kutloisiso. Ka lebaka la lisebelisoa tse bonolo, theko e tlaase le phello e ntle, ts'ebetso ea khatello ea static e feteletseng e sebelisoa haholo ke baetsi ba lisele tsa aluminium alloy load.

(3) mokhoa oa ho tsofala oa vibrate

Sele ea mojaro e kentsoe sethaleng sa vibrate e nang le "sinusoidal thrust" e lekantsoeng e finyellang litlhoko tsa botsofali ba vibrate, 'me maqhubu a hakanngoa ho ea ka mefuta e lekantsoeng ea sele e boima ho fumana hore na moroalo o sebelisitsoeng oa thothomelo, nako ea ho sebetsa le nako ea ho thothomela. Botsofali ba resonance bo molemo ho feta botsofali ba vibrate ka ho lokolla khatello ea maikutlo e setseng, empa maqhubu a tlhaho a sele ea mojaro a tlameha ho lekanngoa. Botsofali ba vibration le botsofali ba resonance bo khetholloa ke tšebeliso e tlase ea matla, nako e khuts'oane, phello e ntle, ha ho na tšenyo holim'a likarolo tsa elastic le ts'ebetso e bonolo. Mokhoa oa ho tsofala ha vibrate o ntse o sa tsejoe hantle. Likhopolo le maikutlo a hlahisoang ke litsebi tsa kantle ho naha li kenyelletsa: theory deformation ea polasetiki, theory ea mokhathala, theory of lattice dislocation slip theory, energy viewpoint le material mechanics views.
