LMEC-8 Zvishandiso zveVakamanikidzwa Vibration uye Resonance
Kumanikidzwa kudedera uye resonance chiitiko chinowanzo shandiswa muinjiniya uye kutsvagisa kwesainzi, senge mukuvaka, michina uye imwe mainjiniya, zvinowanzo fanirwa kudzivirira resonance chiitiko kuona mhando yeinjiniya. Mune mamwe mabhizimusi epetrochemical, resonance phenomenon mutsara unoshandiswa kuona kuwanda kwemvura uye kukwirira kwemvura, saka kumanikidzwa kudedera uye resonance yakakosha mitemo yepanyama, iyo inonyanya kufarirwa mufizikisi neinjiniya tekinoroji Kutarisisa. Chishandiso chinoshandisa kugadzirisa forogo vibration system sechinhu chekutsvagisa, simba remagetsi remagetsi emagetsi inonakidza coil sesimba rinonakidza, uye magetsi emagetsi senge amplitude sensor kuyera hukama pakati pe vibration amplitude uye kutyaira simba frequency, uye kudzidza kumanikidza vibration uye resonance phenomenon nemutemo wayo .
Kuedza
1. Dzidza hukama huripo pakati peakakura uye nekumanikidza kuwanda kwegadziriro yeforogo vibration system inotungamirwa nesimba rekunze rekunze. Pima uye ronga hukama hwavo hwehukama, uye tora iyo resonance frequency uye kupinza kweiyo vibration system (iyi kukosha kwakaenzana neiyo Q kukosha).
2. Kuyera hukama pakati pekudengenyeka uye kuwanda kwemaoko akaenzana eforoko yekugadzirisa. Tora hukama hwehukama pakati peiyo vibration frequency f (kureva resonance frequency) uye block block m yakasungirirwa kune yekugadzirisa forogo maoko pane imwe nzvimbo.
3. Sarudza huremu hwema bhuroko ehuremu hwakabatanidzwa nemaoko ekugadzira forogo nekuyera resonance frequency.
4. Enzanisa iyo resonance frequency uye kupinza kweiyo tuning fork kana uchichinja iyo vibration mamiriro uye nekuwedzera iyo damping simba yeiyo tuning forogo uye ita enzaniso.
Iri bhuku rekuraira rine kumisikidza kwekuyedza, misimboti, nhanho-nhanho mirairo, uye mienzaniso yemhedzisiro yekuedza. Ndokumbirawo ubaye Kuongorora Dzidziso uye Zviri Mukati kuti uwane rumwe ruzivo nezve ichi chishandiso.
