ʻO nā kumu o ka leo Vibration i nā kaʻa kaʻa synchronous magnet mau loa

ʻO ka haʻalulu onā kaʻa kaʻa hoʻokahi magnet paʻamai ʻekolu mau ʻano: ka leo aerodynamic, ka haʻalulu mechanical, a me ka haʻalulu electromagnetic. Hoʻokumu ʻia ka walaʻau Aerodynamic e nā loli wikiwiki i ke kaomi ea i loko o ka kaʻa a me ka friction ma waena o ke kinoea a me ke ʻano kaʻa. Hoʻokumu ʻia ka haʻalulu mīkini e ka deformation elastic i kēlā me kēia manawa o nā bearings, nā hemahema geometric, a me ke ʻano ʻole o ka rotor shaft. Hoʻokumu ʻia ka haʻalulu electromagnetic e ka electromagnetic excitation, a ke hana nei ka lewa magnetic field ma ka stator core, e hoʻoneʻe ana i ka radial deformation o ka stator, i lawe ʻia i ka pahu kaʻa a hoʻomālamalama i ka walaʻau. ʻOiai ka liʻiliʻi o ka ʻāpana tangential o ke kahua magnetic gap, hiki ke hoʻoulu i ka cogging torque ripple a me ka haʻalulu kaʻa. I ka hooikaika ana onā kaʻa kaʻa hoʻokahi magnet paʻa, ʻo ka electromagnetic excitation ke kumu nui o ka vibration.

I ka pae hoʻolālā mua onā kaʻa kaʻa hoʻokahi magnet paʻa, ma ka hoʻokumu ʻana i kahi hiʻohiʻona pane vibration, ka nānā ʻana i nā waiwai o ka electromagnetic excitation a me nā hiʻohiʻona ikaika o ka hale, wānana a loiloi i ke kiʻekiʻe o ka leo haʻalulu, a me ka hoʻolālā ʻana i ka hoʻolālā no ka haʻalulu, hiki ke hoʻemi ʻia ka walaʻau haʻalulu, hiki ke hoʻomaikaʻi ʻia ka hana kaʻa. a hiki ke hoʻopōkole ʻia ka pōʻaiapili hoʻomohala.

Hiki ke hōʻuluʻulu ʻia ka holomua noiʻi o kēia manawa i ʻekolu mau ʻano:

1. Ka noiʻi e pili ana i ka hoʻoulu ʻana electromagnetic: ʻO ka electromagnetic excitation ke kumu kumu o ka haʻalulu, a ke hoʻomau nei ka noiʻi no nā makahiki he nui. ʻO ka noiʻi mua ʻana me ka helu ʻana i ka hāʻawi ʻana i nā mana electromagnetic i loko o nā kaʻa a me ka loaʻa ʻana o nā kumu hoʻohālikelike no nā ikaika radial. I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia nā ʻano simulation element hope a me ka nānā ʻana i nā helu, a ua aʻo nā loea kūloko a me nā ʻāina ʻē i ka mana o nā hoʻonohonoho pole slot ʻokoʻa ma ka cogging torque o nā motor synchronous magnet mau loa.

2. No ka noiʻi ʻana i nā hiʻohiʻona ʻano hana: ʻO nā hiʻohiʻona ʻano o kahi hale e pili kokoke ana i kāna pane haʻalulu, ʻoi aku ka nui o ka manawa kokoke i ke alapine maoli o ka hale, e hiki mai ka resonance. Ua aʻo nā ʻepekema kūloko a me nā ʻāina ʻē i nā hiʻohiʻona o nā ʻōnaehana stator kaʻa ma o nā hoʻokolohua a me nā hoʻohālikelike, me nā mea e pili ana i nā alapine modal e like me nā mea waiwai, modulus elastic, a me nā ʻāpana hana.

3. Noiʻi e pili ana i ka Vibration Response ma lalo o ka Electromagnetic Excitation: ʻO ka pane haʻalulu o kahi kaʻa ka mea i hana ʻia e ka electromagnetic excitation e hana ana ma nā niho stator. Nānā nā kānaka noiʻi i ka puʻunaue spatiotemporal o ka ikaika electromagnetic, hoʻouka i ka electromagnetic excitation ma luna o ke ʻano stator motor, a loaʻa nā helu helu a me nā hopena hoʻokolohua o ka pane haʻalulu. Ua noiʻi pū nā mea noiʻi i ka hopena o ka coefficient damping o ka mea pūpū i ka pane haʻalulu.
