LMEC-8 Apparatus of Forced Vibration uye Resonance

Tsanangudzo Pfupi:

Kumanikidzwa vibration uye resonance phenomenon inowanzo shandiswa muinjiniya nekutsvaga kwesainzi, senge mukuvaka, muchina uye humwe huinjiniya, zvinowanzodikanwa kudzivirira resonance chiitiko kuti ive nechokwadi chemhando yeinjiniya.Mune mamwe mabhizinesi epetrochemical, resonance phenomenon mutsara unoshandiswa kuona huwandu hwemvura uye kureba kwemvura, saka kumanikidzwa vibration uye resonance ndiyo yakakosha mitemo yemuviri, iyo iri kuwedzera uye yakakurumbira mufizikisi uye engineering tekinoroji.Icho chiridzwa chinoshandisa tuning fork vibration system sechinhu chekutsvagisa, electromagnetic simba remagetsi inonakidza coil sesimba rinonakidza, uye electromagnetic coil se amplitude sensor kuyera hukama pakati pe vibration amplitude uye kutyaira simba frequency, uye kudzidza kumanikidza vibration uye resonance chiitiko uye mutemo wayo. .
