Munda Wofunsira
Makina oyesa kutopa a electro-hydraulic servo dynamic kutopa (otchedwa makina oyesera) amagwiritsidwa ntchito makamaka poyesa mawonekedwe amphamvu azitsulo, zopanda zitsulo komanso zophatikizika pa kutentha kwachipinda (kapena kutentha kwambiri ndi kutsika, malo owononga).Makina oyesera amatha kuchita mayeso otsatirawa:
Tensile ndi compression mayeso
Mayeso a kukula kwa Crack
Dongosolo lotsekeka la servo lopangidwa ndi chowongolera magetsi, valavu ya servo, sensor yonyamula katundu, sensa yosuntha, extensometer ndi kompyuta zimatha kuwongolera molondola ndikuyesa mayeso, ndikuyesa kuyesa mayeso monga mphamvu yoyesa, kusamuka, kusinthika, torque, ndi ngodya.
Makina oyesera amatha kuzindikira sine wave, mafunde a katatu, mafunde a square, mafunde a sawtooth, anti-sawtooth wave, pulse wave ndi ma waveform ena, ndipo amatha kuchita zolimbitsa thupi, kuponderezana, kupindika, kutsika pang'ono komanso kuyezetsa kutopa kwambiri.Itha kukhalanso ndi chipangizo choyesera zachilengedwe kuti amalize kuyesa koyerekeza zachilengedwe pazitentha zosiyanasiyana.
Makina oyesera ndi osinthika komanso osavuta kugwiritsa ntchito.Kukweza kwamitengo yosuntha, kutseka, ndi kuyika kwazithunzi zonse zimamalizidwa ndi mabatani.Imagwiritsa ntchito ukadaulo wapamwamba kwambiri wa hydraulic servo drive kuti ikweze, masensa apamwamba kwambiri osunthika komanso masensa apamwamba kwambiri a magnetostrictive displacement kuti ayeze mphamvu ya chitsanzocho.Mtengo ndi kusamuka.Njira yoyezera ndi kuwongolera ya digito yonse imazindikira kuwongolera kwa PID kwa mphamvu, kusinthika ndi kusamuka, ndipo kuwongolera kulikonse kumatha kusinthidwa bwino., Pulogalamu yoyesera imagwira ntchito mu WINDOWS XP/Win7 Chinese chilengedwe, ndi ntchito zamphamvu zogwiritsira ntchito deta, miyeso yoyesera ndi zotsatira zoyesa zimasungidwa, kuwonetsedwa ndi kusindikizidwa.Njira yoyeserera imaphatikizidwa kwathunthu muulamuliro wamakompyuta.Makina oyesera ndi njira yabwino yoyesera yotsika mtengo ya mabungwe ofufuza zasayansi, zomangamanga zazitsulo, chitetezo cha dziko ndi mafakitale ankhondo, mayunivesite, kupanga makina, zoyendera ndi mafakitale ena.
