Pendulum yeLMEC-7 Pohl
LMEC-7Pendulum yaPohl
Kuedza
1. Kutenderera kwakasununguka - kuyerwa kwekuenderana pakati pehukuru hwevhiri rekuenzanisa θ nenguva yekutenderera kwakasununguka T
2. Kuziva kwechinhu chinoderedza mvura β.
3. Kuziva hunhu hweamplitude-frequency uye ma curves ehunhu hwephase-frequency ekumanikidzwa kwekuzunguzika.
4. Kudzidza nezvemhedzisiro yekudzikisa kwakasiyana-siyana kwesimba pakumanikidzwa kwesimba uye kutarisa zviitiko zve resonance.
5. Dzidza kushandisa nzira ye stroboscopic kuti uone huwandu hwezvinhu zvinofamba, zvakaita semusiyano wezvikamu.
Magadzirirwo Makuru
| Kuoma kwechirimo chinhu K | shanduko iri pasi pe2% munguva yekudedera kwemahara |
| Kuyera nguva | kurongeka 0.001s, kukanganisa kwekuyera kutenderera 0.2% |
| pendulum yemakanika | ine nzvimbo dzekuisa indekisi, inoisa indekisi 2°, radius 100 mm |
| Kuyera amplitude | kukanganisa ±1° |
| Sensor yemagetsi A | kuonekwa kwezviratidzo zve photoelectric zviviri |
| sensor yemagetsi B | kuonekwa kwezviratidzo zve photoelectric imwe chete |
| Kumhanya kwemota (kumanikidza mafrequency) | 30 - 45 rpm uye inogadziriswa nguva dzose |
| Kusagadzikana kwekumhanya kwemota | pasi pe0.05%, zvichiita kuti bvunzo dzirambe dzakagadzikana |
| Kuderedza simba rehurongwa | pasi pe2° pakuora kwe amplitude |
Zvidimbu
Zvikamu zvesystem: Pohl resonance experimental device, Pohl resonance experimental controller, separate flash assembly, 2 photoelectric sensors (imwe neimwe yerudzi rweA nerudzi rweB)
Kugadzirira kwePohl resonance.
1. Chitubu chekuoma kwesimba K: shanduko iri pasi pe2% munguva yekuzununguka kwemahara.
2. Kuyera nguva (madenderedzwa gumi): kurongeka 0.001s, kukanganisa kwekuyera kutenderera 0.2%.
3. Kudzikisa simba remagetsi kana pasina kudzima simba remagetsi: pasi pe2° pakuora kweamplitude.
4. Pendulum yemakanika: ine nzvimbo dzekuisa indekisi, inoisa indekisi 2°, radius 100 mm.
5. Kuyera amplitude: kukanganisa ±1°; nzira yekuyera amplitude: kuona photoelectric.
6. Sensor yemagetsi A: kuona zviratidzo zvemagetsi zviviri; sensor yemagetsi B: kuona zviratidzo zvemagetsi chimwe chete.
7. Kumhanya kwemota (kunomanikidza mafrequency): 30 - 45 rpm uye inogadziriswa nguva dzose.
8. Kusagadzikana kwemota: pasi pe0.05%, zvichiita kuti bvunzo dzirambe dzakagadzikana.
9. Kusarudza musiyano wechikamu.
Nzira mbiri dzekusarudza musiyano wechikamu: stroboscopic nemetrological, nekutsauka kuri pasi pe3° pakati penzira mbiri idzi.
Nhamba yekuyera yenzira yemetrological iri pakati pe50° ne160°.
Kuyera kweStroboscopic kuri pakati pe0° ne180°; kutsauka kwakadzokororwa <2°.
10. Flash: dhiraivha yemagetsi mashoma, flash yakasiyana neyuniti yekuyedza, nguva yeflash inoenderera mberi ye2ms, ruvara rutsvuku runokwezva maziso.
11. Ruzha rwakaderera, hapana nyonganyonga kana kusagadzikana panguva yekuedza kweboka.
Pohl resonance experimental controller.
1. Chinotonga chekuedza chakakosha chinoshandiswa kuunganidza nekuratidza data; chiratidziro chikuru cheLCD chine dot-matrix chinoshandiswa, chine menyu yekutungamira kuyedza, manotsi ekukurudzira (bhuku remirairo remagetsi), uye kuratidza nekutarisa data rekuyedza.
2. Nzvimbo yekudzora yakatsaurirwa yema strobes.
