LMEC-7 Pohl kaThixo Pendulum

I-LMEC-7Pohl's Pendulum

Iimvavanyo

1.I-oscillation yasimahla - umlinganiso wembalelwano phakathi kobukhulu bevili lokulinganisa θ kunye nexesha lokuhamba simahla T

2.Ukumiselwa kwemeko yokudambisa β.

3.Ukumiselwa kweempawu ze-amplitude-frequency kunye ne-phase-frequency characteristic curves of vibrations inforcement.

4. Uphononongo lwefuthe lokuthomalalisa okwahlukeneyo kwiintshukumo ezinyanzelisiweyo kunye nokuqwalaselwa kweziganeko zeresonance.

5.Funda ukusebenzisa indlela ye-stroboscopic ukumisela imiyinge ethile yezinto ezihambayo, ezinjengomahluko wesigaba.

Iinkcukacha eziphambili

Iinkcukacha

Amacandelo eSistim: Isixhobo sovavanyo se-Pohl resonance, isilawuli sokulinga se-Pohl, i-flash assembly eyahlukileyo, izinzwa ze-photoelectric ezi-2 (enye yohlobo A kunye nohlobo B)

Pohl resonance experimental set-up.

1. Inkani yasentwasahlobo into K: ngaphantsi kwe-2% utshintsho kwixesha lokungcangcazela kwamahhala.

2. Umlinganiselo wexesha (imijikelo eli-10): ukuchaneka 0.001s, impazamo yokulinganisa umjikelo 0.2%.

3. I-system damping ngokungabikho kwe-electromagnetic damping: ngaphantsi kwe-2 ° ngokubola kwe-amplitude.

4. I-pendulum yomatshini: kunye ne-slots indexing, i-indexing 2 °, i-radius 100 mm.

5. Umlinganiselo we-amplitude: impazamo ±1°; indlela yokulinganisa i-amplitude: ukufunyanwa kwe-photoelectric.

6. Inzwa ye-Photoelectric A: ukufunyanwa kwezibonakaliso ze-photoelectric ezimbini; I-sensor ye-photoelectric B: ukufunyanwa kwezibonakaliso ze-photoelectric enye.

7. Isantya seMoto (ukunyanzeliswa kwe-frequency) uluhlu: 30 - 45 rpm kunye nokulungelelaniswa ngokuqhubekayo.

8. Ukungazinzi kwesantya seMoto: ngaphantsi kwe-0.05%, ukuqinisekisa umjikelezo wovavanyo oluzinzile.

9. Ukuzimisela umahluko wesigaba.

Iindlela ezimbini zokumisela umahluko wesigaba: i-stroboscopic kunye ne-metrological, kunye nokutenxa ngaphantsi kwe-3 ° phakathi kweendlela ezimbini.

Uluhlu lomlinganiselo wendlela ye-metrological phakathi kwe-50 ° kunye ne-160 °.

Uluhlu lomlinganiselo weStroboscopic phakathi kwe-0 ° kunye ne-180 °; ukutenxa komlinganiselo ophindaphindiweyo <2 °.

10. I-Flash: i-low voltage drive, i-flash eyahlukileyo kwiyunithi yovavanyo, i-2ms yexesha eliqhubekayo lokukhanya, umbala obomvu obomvu.

11. Ingxolo ephantsi, akukho kuphazamiseka okanye ukuphazamiseka ngexesha lovavanyo lweqela.

Pohl resonance isilawuli sokulinga.

1. Umlawuli okhethekileyo wokulinga usetyenziselwa ukuqokelela nokubonisa idatha; i-dot-matrix ye-LCD ibonisa i-dot-matrix enkulu isetyenziswa, kunye neemenyu zokukhokela umfuniselo, amanqaku akhuthazayo (incwadana yemiyalelo ye-electronic), kunye nokubonisa kunye nokujonga idatha yovavanyo.

2. Ujongano olunikezelweyo lolawulo lweestrobes.
