LMEC-7 Pohl's Pendulum
LMEC-7Pohl's Pendulum
Miedzo
1.Mahara oscillation - kuyerwa kwetsamba pakati peamplitude yevhiri rechiyero θ uye nguva yemahara oscillation T.
2.Kutsunga kwechinhu chinonyorova β.
3.Kutsunga kweamplitude-frequency characterism uye phase-frequency characteristic curves yekumanikidzirwa vibrations.
4.Kudzidza kwemhedzisiro yekudonha kwakasiyana pakudengenyeka kwekumanikidzwa uye kucherechedza resonance phenomena.
5.Dzidza kushandisa nzira ye stroboscopic kuti uone humwe huwandu hwezvinhu zvinofamba, zvakadai sekusiyana kwechikamu.

Details
Zvikamu zveSitimu: Pohl resonance yekuedza mudziyo, Pohl resonance yekuyedza controller, yakaparadzana flash assembly, 2 photoelectric sensors (imwe neimwe yerudzi A uye mhando B)
Pohl resonance experimental set-up.
1. Chitubu chakasindimara chinhu K: isingasviki 2% shanduko munguva yemahara vibration.
2. Kuyera nguva (10 cycles): kunyatsoita 0.001s, kutenderera kuyerwa kukanganisa 0.2%.
3. System damping mukusavapo kwe electromagnetic damping: isingasviki 2 ° per amplitude decay.
4. Mechanical pendulum: ine indexing slots, indexing 2 °, radius 100 mm.
5. Amplitude kuyerwa: kukanganisa ± 1 °; amplitude kuyerwa nzira: kuona photoelectric.
6. Photoelectric sensor A: kuonekwa kwekaviri photoelectric zviratidzo; photoelectric sensor B: kuonekwa kweimwe photoelectric zviratidzo.
7. Motokari kumhanya (kumanikidzira frequency) chiyero: 30 - 45 rpm uye inoramba ichigadziriswa.
8. Motokari inokurumidza kusagadzikana: isingasviki 0.05%, kuve nechokwadi chekugadzirisa kwakagadzikana kutenderera.
9. Phase kusiyana kutsunga.
Nzira mbiri dzekugadzirisa mutsauko wechikamu: stroboscopic uye metrological, nekutsauka kwepasi pe3 ° pakati penzira mbiri idzi.
Kuyera kweyero yemetroological method iri pakati pe50° ne160°.
Chiyero cheStroboscopic pakati pe0 ° ne180 °; kudzokororwa kuyerwa kutsauka <2 °.
10. Kupenya: low voltage drive, flash yakasiyana kubva pakuedza unit, 2ms inoenderera mberi flash time, ruvara rweziso-inobata tsvuku.
11. Mutsindo wakaderera, hapana kukanganisa kana kusagadzikana panguva yekuedza kweboka.
Pohl resonance experimental controller.
1. Mutongi anokosha wekuedza anoshandiswa kuunganidza uye kuratidza data; hombe dot-matrix LCD kuratidza inoshandiswa, ine mamenu ekutungamira kuyedza, inotsikisa manotsi (electronic instruction manual), uye kuratidza uye kutarisa kumashure ekuyedza data.
2. Dedicated control interface ye strobes.
