ʻO G kahi ʻāpana maʻamau e wehewehe i ka amplitude o ka haʻalulu manā motika haʻalulua me nā mea hana hoʻokani pila. Hōʻike ia i ka wikiwiki ma muli o ka ʻumekaumaha, ʻo ia ka 9.8 mau mika no kekona squared (m/s²).
Ke ʻōlelo nei mākou i kahi pae haʻalulu o 1G, ʻo ia hoʻi, ua like ka vibration amplitude me ka wikiwiki i ʻike ʻia e kekahi mea ma muli o ka gravity. ʻO kēia hoʻohālikelike e hiki ai iā mākou ke hoʻomaopopo i ka ikaika o ka haʻalulu a me kona hopena i ka ʻōnaehana a i ʻole ka noi.
He mea nui e hoʻomaopopo he ala wale nō ʻo G e hōʻike ai i ka amplitude o ka haʻalulu, hiki ke ana ʻia ma nā ʻāpana ʻē aʻe e like me nā mika no ke kekona squared (m/s²) a i ʻole millimeters per second squared (mm/s²). nā koi kiko'ī a kūlana paha. Eia nō naʻe, ʻo ka hoʻohana ʻana iā G ma ke ʻano he ʻāpana e hāʻawi i kahi kuhikuhi kuhikuhi a kōkua i nā mea kūʻai aku e hoʻomaopopo i nā pae haʻalulu ma ke ʻano kūpono.
He aha ke kumu o ka hoʻohana ʻole ʻana i ka neʻe (mm) a i ʻole ka ikaika (N) ma ke ʻano he ana o ka amplitude vibration?
Nā motika haʻaluluʻaʻole hoʻohana wale ʻia. Hoʻokomo pinepine ʻia lākou i loko o nā ʻōnaehana ʻoi aku ka nui me ka nui o ka pahuhopu. No ke ana ʻana i ka amplitude vibration, kau mākou i ke kaʻa ma luna o ka nui i ʻike ʻia a hoʻohana i ka accelerometer e hōʻiliʻili i ka ʻikepili. Hāʻawi kēia iā mākou i kahi kiʻi maʻalahi o nā hiʻohiʻona haʻalulu holoʻokoʻa o ka ʻōnaehana, a laila mākou e hōʻike ai i kahi kiʻi ʻano hana maʻamau.
Hoʻoholo ʻia ka ikaika i hana ʻia e ka motika vibration e ka hoohalike penei:
$$F = m \manawa r \manawa \omega ^{2}$$
(F) hōʻike i ka ikaika, (m) hōʻike i ka nuipaʻa o ka eccentric nuipaʻa ma luna o ke kaʻa (me ka nānā 'ole o ka'ōnaehana holoʻokoʻa), (r) hoike i ka eccentricity o ka eccentric nuipa, a (Ω) hoike i ke alapine.
Pono e hoʻomaopopo ʻia ʻo ka ikaika vibration wale nō o ke kaʻa kaʻa e nānā ʻole i ka mana o ka nuipaʻa. No ka laʻana, koi ka mea kaumaha i ka ikaika e hana i ka pae like o ka wikiwiki e like me ka mea liʻiliʻi a māmā. No laila inā hoʻohana nā mea ʻelua i ka mīkini hoʻokahi, e haʻalulu ka mea kaumaha i kahi amplitude ʻoi aku ka liʻiliʻi, ʻoiai ke hoʻopuka nei nā motika i ka ikaika like.
ʻO kekahi hiʻohiʻona o ke kaʻa ʻo ia ka vibration frequency:
$$ f = \frac{Motor \: Wikiwiki \:(RPM)}{60}$$
Hoʻopili pololei ʻia ka neʻe ʻana e ka haʻalulu e ka pinepine o ka haʻalulu. I loko o kahi hāmeʻa haʻalulu, hana ʻino nā ikaika i ka ʻōnaehana. No kēlā me kēia ikaika i hana ʻia, aia ka ikaika like a kū'ē i ka hopena. Ke piʻi aʻe ka alapine o ka haʻalulu, e emi ana ka manawa ma waena o ka hiki ʻana mai o nā mana kū'ē.
No laila, liʻiliʻi ka manawa e hoʻoneʻe ʻia ai ka ʻōnaehana ma mua o ka hoʻopau ʻana o nā pūʻali kūʻē. Eia kekahi, ʻoi aku ka liʻiliʻi o kahi mea kaumaha ma mua o kahi mea māmā ke kau ʻia i ka ikaika like. Ua like kēia me ka hopena i ʻōlelo ʻia ma mua e pili ana i ka ikaika. Pono ka mea kaumaha i ka ikaika e hiki ai ke hoʻoneʻe like me ka mea māmā.
Kāhea iā mā˚ou
Hiki i kā mākou hui ke hāʻawi i ke kākoʻo a me ke kōkua meuila uilahuahana. Hoʻomaopopo mākou he paʻakikī ka hoʻomaopopo ʻana, ka wehewehe ʻana, ka hōʻoia ʻana a me ka hoʻohui ʻana i nā huahana kaʻa i nā noi hopena. Loaʻa iā mākou ka ʻike a me ka ʻike e kōkua i ka hōʻemi ʻana i nā pilikia e pili ana i ka hoʻolālā kaʻa, hana a me ka lako. E hoʻokaʻaʻike i kā mākou hui i kēia lā e kūkākūkā i kāu mau pono pili kaʻa a loaʻa kahi hopena e kūpono i kāu mau koi kikoʻī. Aia mākou e kōkua.
E kūkākūkā i kāu mau alakaʻi loea
Kōkua mākou iā ʻoe e pale i nā pōʻino e hāʻawi i ka maikaʻi a me ka waiwai o kāu pono micro brushless ponoʻī, i ka manawa a me ka uku kālā.
