Pendulum ya LMEC-7 Pohl
LMEC-7Pendulum ya Pohl
Zoyesera
1. Kusinthasintha kwaulere - kuyeza kufanana pakati pa kutalika kwa gudumu lolinganiza θ ndi nthawi ya kusinthasintha kwaulere T
2. Kudziwa β yomwe imapangitsa kuti madzi asamaundane.
3. Kudziwa momwe ma amplitude-frequency amakhalira komanso momwe ma phase-frequency amakhalira ndi ma curve okakamiza.
4. Kuphunzira za momwe damping yosiyana imakhudzira kugwedezeka kokakamizidwa ndi kuwona zochitika za resonance.
5. Phunzirani kugwiritsa ntchito njira ya stroboscopic kuti mudziwe kuchuluka kwa zinthu zoyenda, monga kusiyana kwa magawo.
Mafotokozedwe Aakulu
| Chinthu cha kuuma kwa masika K | kusintha kosakwana 2% mu nthawi ya kugwedezeka kwaulere |
| Kuyeza nthawi | kulondola 0.001s, cholakwika cha muyeso wa kuzungulira 0.2% |
| Pendulum yamakina | yokhala ndi malo oikira chizindikiro, oikira chizindikiro 2°, utali wozungulira 100 mm |
| Muyeso wa kukula kwa matalikidwe | cholakwika ±1° |
| Sensa yamagetsi yojambula zithunzi A | kuzindikira zizindikiro ziwiri za photoelectric |
| sensa yamagetsi yojambula B | kuzindikira zizindikiro za photoelectric imodzi |
| Liwiro la injini (kukakamiza ma frequency) osiyanasiyana | 30 - 45 rpm ndipo nthawi zonse imasinthasintha |
| Kusakhazikika kwa liwiro la injini | zosakwana 0.05%, kuonetsetsa kuti mayeso akuyenda bwino |
| Kuchepetsa mphamvu ya dongosolo | kutentha kosakwana 2° pa kuwonongeka kwa amplitude |
Tsatanetsatane
Zigawo za dongosolo: Chipangizo choyesera cha Pohl resonance, chowongolera choyesera cha Pohl resonance, msonkhano wosiyana wa flash, masensa awiri a photoelectric (chimodzi mwa mitundu A ndi mtundu B)
Kukhazikitsa kwa Pohl resonance experimental.
1. Kuuma kwa masika K: kusintha kosakwana 2% mu nthawi ya kugwedezeka kwaulere.
2. Kuyeza nthawi (ma cycle 10): kulondola 0.001s, cholakwika cha muyeso wa cycle 0.2%.
3. Kuchepetsa mphamvu ya dongosolo popanda kuwononga mphamvu yamagetsi: osachepera 2° pa kuwonongeka kwa amplitude.
4. Pendulum yamakina: yokhala ndi mipata yolozera, yolozera 2°, utali wa radius 100 mm.
5. Kuyeza kwa kukula: cholakwika ±1°; njira yoyezera kukula: kuzindikira kwa kuwala kwa dzuwa.
6. Sensa yamagetsi A: kuzindikira zizindikiro ziwiri zamagetsi; sensa yamagetsi B: kuzindikira zizindikiro zamagetsi imodzi.
7. Liwiro la injini (mafupipafupi okakamiza): 30 - 45 rpm ndipo limasinthasintha mosalekeza.
8. Kusakhazikika kwa liwiro la injini: zosakwana 0.05%, kuonetsetsa kuti mayeso akuyenda bwino.
9. Kutsimikiza kusiyana kwa magawo.
Njira ziwiri zodziwira kusiyana kwa gawo: stroboscopic ndi metrological, ndi kupotoka kwa zosakwana 3° pakati pa njira ziwirizi.
Mulingo woyezera wa njira yoyezera ndi pakati pa 50° ndi 160°.
Muyeso wa stroboscopic uli pakati pa 0° ndi 180°; kupotoka kobwerezabwereza kwa muyeso <2°.
10. Flash: drive yamagetsi otsika, flash yosiyana ndi chipangizo choyesera, nthawi yowunikira yosalekeza ya 2ms, utoto wofiira wokopa maso.
11. Phokoso lochepa, palibe chisokonezo kapena kusasangalala panthawi yoyesera gulu.
Chowongolera choyesera cha Pohl resonance.
1. Chowongolera chapadera choyesera chimagwiritsidwa ntchito kusonkhanitsa ndikuwonetsa deta; chiwonetsero chachikulu cha LCD chokhala ndi madontho chimagwiritsidwa ntchito, chokhala ndi menyu yotsogolera kuyesera, zolemba zopempha (buku la malangizo amagetsi), ndikuwonetsa ndikuwunikanso deta yoyesera.
2. Mawonekedwe odziyimira pawokha a ma strobe.
