LMEC-7Pohl's Pendulum
Kev sim
1.Free oscillation - kev ntsuas ntawm kev sib txuas lus ntawm lub amplitude ntawm lub tshuav log θ thiab lub sij hawm ntawm dawb oscillation T
2.Kev txiav txim siab ntawm qhov damping factor β.
3.Kev txiav txim siab ntawm qhov amplitude-frequency yam ntxwv thiab theem-zaus cov yam ntxwv nkhaus ntawm yuam kev vibrations.
4.Study cov nyhuv ntawm txawv damping ntawm yuam kev vibrations thiab kev soj ntsuam ntawm resonance phenomena.
5. Kawm siv txoj kev stroboscopic los txiav txim seb qhov ntau npaum li cas ntawm cov khoom txav, xws li theem sib txawv.

Paub meej
Cov Cheebtsam: Pohl resonance sim ntaus ntawv, Pohl resonance sim maub los, cais flash los ua ke, 2 photoelectric sensors (ib qho ntawm txhua hom A thiab hom B)
Pohl resonance kev sim teeb tsa.
1. Caij nplooj ntoos hlav stubbornness factor K: tsawg dua 2% hloov nyob rau hauv lub sij hawm dawb vibration.
2. Lub sij hawm ntsuas (10 lub voj voog): qhov tseeb 0.001s, lub voj voog ntsuas qhov yuam kev 0.2%.
3. Qhov system damping thaum tsis muaj electromagnetic damping: tsawg dua 2 ° ib amplitude lwj.
4. Mechanical pendulum: nrog indexing slots, indexing 2 °, vojvoog 100 mm.
5. Amplitude ntsuas: yuam kev ± 1°; amplitude ntsuas txoj kev: photoelectric nrhiav.
6. Photoelectric sensor A: nrhiav pom ntawm ob chav photoelectric teeb liab; photoelectric sensor B: nrhiav pom ntawm ib qho photoelectric signals.
7. Lub cev muaj zog ceev (yuam zaus) ntau yam: 30 - 45 rpm thiab kho tsis tu ncua.
8. Lub cev muaj zog ceev tsis ruaj khov: tsawg dua 0.05%, ua kom lub voj voog ntsuas ruaj khov.
9. Kev txiav txim siab qhov sib txawv.
Ob txoj hauv kev ntawm kev txiav txim siab theem sib txawv: stroboscopic thiab metrological, nrog qhov sib txawv ntawm tsawg dua 3 ° ntawm ob txoj kev.
Kev ntsuas ntau ntawm txoj kev ntsuas ntsuas yog nyob nruab nrab ntawm 50 ° thiab 160 °.
Stroboscopic ntsuas ntau ntawm 0 ° thiab 180 °; rov ntsuas qhov sib txawv <2°.
10. Flash: tsis tshua muaj hluav taws xob tsav, flash cais los ntawm chav sim, 2ms txuas ntxiv lub sijhawm flash, xim qhov muag pom liab.
11. Tsis tshua muaj suab nrov, tsis muaj kev cuam tshuam los yog tsis xis nyob thaum kev sim pab pawg.
Pohl resonance sim maub los.
1. Ib qho kev sim tshwj xeeb yog siv los sau thiab tso saib cov ntaub ntawv; ib tug loj dot-matrix LCD zaub yog siv, nrog rau cov ntawv qhia zaub mov los qhia qhov kev sim, ua kom cov ntawv ceeb toom (electronic instruction manual), thiab tso saib thiab xyuas cov ntaub ntawv sim rov qab.
2. Dedicated tswj interface rau strobes.
