Kev vibration ntawmruaj khov hlau nplaum synchronous motorsFeem ntau yog los ntawm peb yam: aerodynamic suab nrov, mechanical vibration, thiab electromagnetic vibration. Aerodynamic suab nrov yog tshwm sim los ntawm kev hloov pauv ceev hauv huab cua hauv lub cev muaj zog thiab kev sib txhuam ntawm cov roj thiab cov qauv ntawm lub cev muaj zog. Mechanical vibration yog tshwm sim los ntawm lub sij hawm elastic deformation ntawm bearings, geometric defects, thiab rotor ncej tsis txaus. Electromagnetic vibration yog tshwm sim los ntawm electromagnetic excitation, thiab cov huab cua sib nqus magnetic teb ua rau lub stator core, ua rau radial deformation ntawm stator, uas yog kis mus rau lub cev muaj zog casing thiab radiates suab nrov. Txawm hais tias lub tangential tivthaiv ntawm cov pa sib nqus magnetic teb yog me me, nws tuaj yeem ua rau cogging torque ripple thiab lub cev muaj zog vibration. Nyob rau hauv lub propulsion ntawmruaj khov hlau nplaum synchronous motors, electromagnetic excitation yog lub hauv paus ntawm kev co.
Nyob rau hauv thawj theem tsim ntawmruaj khov hlau nplaum synchronous motors, los ntawm kev tsim cov qauv kev vibration, tshuaj xyuas cov khoom ntawm electromagnetic excitation thiab dynamic yam ntxwv ntawm cov qauv, kwv yees thiab ntsuam xyuas cov theem ntawm kev co suab nrov, thiab optimizing tus tsim rau kev co, vibration suab nrov yuav txo tau, lub cev muaj zog kev ua tau zoo tuaj yeem txhim kho, thiab lub voj voog kev loj hlob tuaj yeem raug luv.
Cov kev tshawb fawb tam sim no tuaj yeem muab sau ua 3 yam:
1.Kev tshawb fawb ntawm electromagnetic excitation: Electromagnetic excitation yog lub hauv paus ua rau kev co, thiab kev tshawb fawb tau ua tsis tu ncua rau ntau xyoo. Kev tshawb fawb thaum ntxov suav nrog suav qhov kev faib tawm ntawm cov hluav taws xob hluav taws xob hauv lub cev muaj zog thiab muab cov qauv tshuaj ntsuam xyuas rau lub zog radial. Nyob rau hauv xyoo tas los no, finite element simulation txoj kev thiab cov zauv tsom xam tau siv dav, thiab cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau kawm txog kev cuam tshuam ntawm cov ncej sib txawv ntawm qhov sib txawv ntawm cov cog torque ntawm cov hlau nplaum ruaj khov synchronous motors.
2. Kev tshawb fawb txog cov yam ntxwv ntawm cov qauv qauv: Cov yam ntxwv ntawm cov qauv ntawm cov qauv zoo sib xws rau nws cov lus teb vibration, tshwj xeeb tshaj yog thaum lub excitation zaus nyob ze rau lub ntuj zaus ntawm cov qauv, resonance yuav tshwm sim. Cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau kawm txog cov yam ntxwv ntawm lub cev muaj zog stator los ntawm kev sim thiab simulations, nrog rau cov yam ntxwv uas cuam tshuam rau cov khoom siv zaus xws li cov khoom siv, elastic modulus, thiab cov qauv tsis sib xws.
3. Kev tshawb fawb txog kev vibration teb nyob rau hauv Electromagnetic Excitation: Lub vibration teb ntawm lub cev muaj zog yog tshwm sim los ntawm electromagnetic excitation ua rau cov hniav stator. Cov kws tshawb fawb tau txheeb xyuas qhov kev faib tawm ntawm cov hluav taws xob hluav taws xob, thauj khoom electromagnetic excitation mus rau lub cev muaj zog stator qauv, thiab tau txais cov lej suav thiab cov txiaj ntsig kev sim ntawm cov lus teb vibration. Cov kws tshawb fawb kuj tau tshawb xyuas qhov cuam tshuam ntawm damping coefficient ntawm lub plhaub khoom ntawm cov lus teb vibration.
