LMEC-7Te Pendulum a Pohl
Ngā whakamātautau
1. Te wiri noa – te ine i te ōritetanga i waenga i te kaha o te wira taurite θ me te wā o te wiri noa T
2. Te whakatau i te tauwehenga whakamākū β.
3. Te whakatau i te āhuatanga o te whānui-auau me ngā ānau āhuatanga o te auau-wāhanga o ngā wiri ā-kaha.
4. Te ako i te pānga o ngā momo whakaitiiti ki ngā wiri ā-kaha me te mātakitaki i ngā āhuatanga orooro.
5. Akohia te whakamahi i te tikanga stroboscopic hei whakatau i ētahi rahinga o ngā mea e neke ana, pērā i ngā rerekētanga ā-wāhanga.
Ngā Whakatakotoranga Matua
| Tauwehenga pakari o te puna K | iti iho i te 2% te huringa o te wā wiri kore utu |
| Te ine i te wā | tika 0.001s, hapa ine huringa 0.2% |
| Pendulum mīhini | me ngā mokowā taupū, taupū 2°, radius 100 mm |
| Te ine i te whānui | hapa ±1° |
| Pūoko hikohiko A | te kimi i ngā tohu hiko-rua |
| pūoko whakaahua-hiko B | te kimi i ngā tohu hiko-whakaahua takitahi |
| Te tere o te motuka (auau akiaki) te whānuitanga | 30 – 45 rpm me te whakarerekētanga tonu |
| Te kore pumau o te tere o te motuka | iti iho i te 0.05%, e whakarite ana i tētahi huringa whakamātautau pumau |
| Te whakamātao pūnaha | iti iho i te 2° mō ia pirau kaha |
Ngā Taipitopito
Ngā wāhanga pūnaha: Pūrere whakamātautau orooro Pohl, pūmana whakamātautau orooro Pohl, huihuinga uira motuhake, 2 pūoko whakaahua-hiko (tētahi o ia momo A me te momo B)
Te whakatūnga whakamātautau orooro Pohl.
1. Tauwehe pakari o te puna K: iti iho i te 2% te huringa o te wā wiri kore utu.
2. Ine wā (10 huringa): tika 0.001s, hapa ine huringa 0.2%.
3. Te whakaiti i te pūnaha i te korenga o te whakaiti hikohiko: iti iho i te 2° mō ia pirau kaha.
4. Pendulum mīhini: me ngā mokowā taupū, taupū 2°, radius 100 mm.
5. Ine i te whānui: hapa ±1°; tikanga ine i te whānui: kimi whakaahua-hiko.
6. Pūoko whakaahua-hiko A: te kimi i ngā tohu whakaahua-hiko takirua; pūoko whakaahua-hiko B: te kimi i ngā tohu whakaahua-hiko takitahi.
7. Te tere o te motuka (auau akiaki): 30 – 45 rpm me te whakarerekē tonu.
8. Te kore pumau o te tere o te motuka: iti iho i te 0.05%, e whakarite ana i te huringa whakamātautau pumau.
9. Te whakatau i te rerekētanga ā-wāhanga.
E rua ngā tikanga mō te whakatau i te rerekētanga ā-wāhanga: te stroboscopic me te ine-ira, me te rerekētanga iti iho i te 3° i waenga i ngā tikanga e rua.
Ko te awhe ine o te tikanga ine ine kei waenga i te 50° me te 160°.
Ko te awhe ine stroboscopic i waenga i te 0° me te 180°; ko te pehanga ine auau <2°.
10. Uira: puku ngaohiko iti, he motuhake te uira mai i te waeine whakamātautau, 2ms te roa o te uira tonu, he tae whero e ātaahua ana te titiro.
11. He iti te haruru, kāore he raruraru, he kore whakamarie rānei i te wā o ngā whakamātautau rōpū.
Pūmana whakamātautau haruru Pohl.
1. Ka whakamahia he pūmana whakamātautau motuhake hei kohikohi me te whakaatu raraunga; ka whakamahia he whakaaturanga LCD ira-ira nui, me ngā tahua hei ārahi i te whakamātautau, hei akiaki i ngā tuhipoka (puka tohutohu hiko), me te whakaatu me te tirotiro i ngā raraunga whakamātautau.
2. Atanga whakahaere motuhake mō ngā hihi.
