Magwero a Phokoso la Vibration mu maginito okhazikika a synchronous motors

Kugwedezeka kwamaginito okhazikika ma synchronous motorsmakamaka zimachokera kuzinthu zitatu: phokoso la aerodynamic, kugwedezeka kwamakina, ndi kugwedezeka kwamagetsi. Phokoso la Aerodynamic limayamba chifukwa cha kusintha kwachangu kwa kuthamanga kwa mpweya mkati mwa mota ndi kukangana pakati pa gasi ndi kapangidwe kagalimoto. Kugwedezeka kwamakina kumachitika chifukwa cha kusinthika kwanthawi ndi nthawi kwa ma bearings, zolakwika za geometric, komanso kusalinganiza kwa ma rotor shaft. Kugwedezeka kwamagetsi kumachitika chifukwa cha kutengeka kwa ma elekitiroma, ndipo gawo la mpweya la maginito limagwira ntchito pachimake cha stator, ndikupangitsa kuti ma radial deformation a stator, omwe amatumizidwa ku casing ya mota ndikutulutsa phokoso. Ngakhale kuti gawo la tangential la mpweya wa maginito ndi laling'ono, limatha kuyambitsa kugwedezeka kwa torque komanso kugwedezeka kwamagalimoto. Mu propulsion yamaginito okhazikika ma synchronous motors, kugwedezeka kwamagetsi ndiye gwero lalikulu la kugwedezeka.

Mu gawo loyamba la mapangidwe amaginito okhazikika ma synchronous motors, pokhazikitsa njira yoyankhira kugwedezeka, kusanthula momwe ma electromagnetic excitation ndi mawonekedwe osinthika amapangidwira, kulosera ndikuwunika kuchuluka kwa phokoso lakugwedezeka, ndikuwongolera kapangidwe kakugwedezeka, phokoso logwedezeka litha kuchepetsedwa, magwiridwe antchito amagalimoto amatha kuwongolera, ndipo mkombero wa chitukuko ukhoza kufupikitsidwa.

Kupita patsogolo kwa kafukufukuyu kungafotokozedwe mwachidule m'magawo atatu:

1.Research on electromagnetic excitation: Chisangalalo cha ma elekitiromagineti ndichomwe chimayambitsa kugwedezeka, ndipo kafukufuku wakhala akupitilira kwa zaka zambiri. Kafukufuku woyambirira adaphatikiza kuwerengera kugawidwa kwa mphamvu zamagetsi zamagetsi mkati mwa ma mota ndikupeza njira zowunikira za mphamvu za radial. M'zaka zaposachedwa, njira zoyeserera zofananira ndi kusanthula manambala zakhala zikugwiritsidwa ntchito kwambiri, ndipo akatswiri apakhomo ndi akunja aphunzira momwe zimakhudzira masinthidwe osiyanasiyana a pologalamu pamakokedwe a maginito okhazikika a ma synchronous motors.

2. Kafukufuku wokhudzana ndi machitidwe opangidwa ndi machitidwe: Makhalidwe a modal a mapangidwe amagwirizana kwambiri ndi kugwedezeka kwake, makamaka pamene maulendo okondweretsa ali pafupi ndi mafupipafupi a chilengedwe, resonance idzachitika. Akatswiri apakhomo ndi akunja aphunzira za kapangidwe ka ma motor stator system kudzera pakuyesa ndi kuyerekezera, kuphatikiza zinthu zomwe zimakhudza ma frequency a modal monga zida, elastic modulus, ndi ma parameter apangidwe.

3. Kafukufuku pa Kuyankha kwa Vibration pansi pa Chisangalalo cha Electromagnetic: Mayankhidwe a kugwedezeka kwa mota amayamba chifukwa champhamvu yamagetsi yomwe imagwira pamano a stator. Ofufuzawo adasanthula kagawidwe ka spatiotemporal kagawidwe ka mphamvu yamagetsi yamagetsi, kudzaza ma elekitiromaginetiki pamapangidwe a motor stator, ndikupeza mawerengedwe a manambala ndi zotsatira zoyeserera pakuyankha kwa kugwedezeka. Ofufuzawo adafufuzanso momwe chigobacho chimakhudzidwira pakuyankhira kwa vibration.
