Izixhobo ze-LMEC-8 zokuGungqa okuQinisekisiweyo kunye nokuHlaziya

Inkcazo emfutshane:

I-Forced vibration kunye ne-resonance phenomenon zihlala zisetyenziswa kubunjineli nakuphando lwesayensi, njengakwizakhiwo, oomatshini kunye nezinye iindlela zobunjineli, kudla ngokuba yimfuneko ukunqanda i-resonance phenomenon ukuqinisekisa umgangatho wobunjineli. Kwamanye amashishini e-petrochemical, umgca we-resonance phenomenon usetyenziselwa ukubona uxinano lolwelo kunye nokuphakama kolwelo, ngoko ke i-forced vibration kunye ne-resonance ziyimithetho ebalulekileyo yendalo, ethandwa ngakumbi kwi-physics kunye ne-engineering technology Ingqalelo. Esi sixhobo sisebenzisa inkqubo ye-tuning fork vibration njengento yophando, amandla e-electromagnetic e-electromagnetic exciting coil njengamandla avuselelayo, kunye ne-electromagnetic coil njenge-amplitude sensor ukulinganisa ubudlelwane phakathi kwe-vibration amplitude kunye ne-driving force frequency, kunye nokufunda i-forced vibration kunye ne-resonance phenomenon kunye nomthetho wayo.
