I-LMEC-7 Pohl's Pendulum
I-LMEC-7I-Pendulum kaPohl
Iimvavanyo
1. Ukushukuma kwamahhala – ukulinganiswa kokuhambelana phakathi kobukhulu bevili lokulinganisela θ kunye nexesha lokushukuma kwamahhala T
2. Ukuchonga i-damping factor β.
3. Ukuchonga uphawu lwe-amplitude-frequency kunye nee-phase-frequency characteristic curves ze-forced vibrations.
4. Uphononongo lwempembelelo yokunciphisa amandla okushukuma okunyanzelekileyo kunye nokujongwa kweziganeko ze-resonance.
5. Funda ukusebenzisa indlela ye-stroboscopic ukufumanisa ubungakanani obuthile bezinto ezihambayo, njengomahluko wesigaba.

| Uluhlu lwesantya semoto (ukunyanzela amaza) | I-30 - 45 rpm kwaye ihlengahlengiswa rhoqo |
| Ukungazinzi kwesantya semoto | ngaphantsi kwe-0.05%, okuqinisekisa umjikelo wovavanyo ozinzileyo |
| Ukunciphisa inkqubo | ngaphantsi kwe-2° ngokubola kwe-amplitude nganye |
Iinkcukacha
Izinto zenkqubo: Isixhobo sovavanyo lwePohl resonance, isilawuli sovavanyo lwePohl resonance, indibano eyahlukileyo yeflash, iisensa ezimbini zephotoelectric (enye nganye yohlobo A kunye nohlobo B)
Useto lovavanyo lwePohl resonance.
1. I-spring stigness factor K: utshintsho olungaphantsi kwe-2% kwixesha lokungcangcazela kwamahhala.
2. Ukulinganisa ixesha (imijikelo eli-10): ukuchaneka kwe-0.001s, impazamo yokulinganisa umjikelo yi-0.2%.
3. Ukudambisa inkqubo xa kungekho damping ye-electromagnetic: ngaphantsi kwe-2° ngokubola kwe-amplitude nganye.
4. I-pendulum yoomatshini: eneendawo zokukhomba, ukukhomba i-2°, i-radius eyi-100 mm.
5. Ukulinganiswa kobukhulu: impazamo ±1°; indlela yokulinganisa ubukhulu: ukufunyanwa kwe-photoelectric.
6. I-Photoelectric sensor A: ukufumanisa imiqondiso ye-photoelectric ephindwe kabini; i-photoelectric sensor B: ukufumanisa imiqondiso ye-photoelectric enye.
7. Isantya semoto (ubuninzi obunyanzelisayo): 30 - 45 rpm kwaye iyalungiseka rhoqo.
8. Ukungazinzi kwesantya semoto: ngaphantsi kwe-0.05%, okuqinisekisa umjikelo wovavanyo oluzinzileyo.
9. Ukumisela umahluko wesigaba.
Iindlela ezimbini zokumisela umahluko wesigaba: i-stroboscopic kunye ne-metrological, kunye nokuphambuka okungaphantsi kwe-3° phakathi kwezi ndlela zimbini.
Uluhlu lokulinganisa lwendlela ye-metrological luphakathi kwe-50° kunye ne-160°.
Umlinganiselo we-Stroboscopic uphakathi kwe-0° kunye ne-180°; ukuphambuka okuphindaphindiweyo komlinganiselo <2°.
10. Ifleshi: idrayivu yevolthi ephantsi, ifleshi eyahlukileyo kwiyunithi yovavanyo, ixesha lefleshi eliqhubekayo le-2ms, umbala obomvu obamba amehlo.
11. Ingxolo ephantsi, akukho kuphazamiseka okanye ukungakhululeki ngexesha lovavanyo lwamaqela.
Isilawuli sovavanyo lwe-Pohl resonance.
1. Isilawuli esikhethekileyo sovavanyo sisetyenziselwa ukuqokelela nokubonisa idatha; kusetyenziswa isibonisi esikhulu se-LCD esine-dot-matrix, kunye neemenyu zokukhokela uvavanyo, amanqaku akhuthazayo (incwadi yemiyalelo ye-elektroniki), kunye nokubonisa nokujonga idatha yovavanyo.
2. Ujongano lolawulo oluzinikeleyo lwee-strobes.
