Unbalanced Response Analysis ntawm Ultra High Speed thiab High Power Fais Fab Ncej System
Lub DyRoBeS rotor dynamics analysis software yog siv los laij cov tseem ceeb ceev thiab qhov uas tsis muaj lus teb ntawm qhov kev lag luam ntev-ntev ntawm kev lag luam 20MW high-speed nce zaus zaus tawg pov tseg lub cev qhov project ncej, thiaj li kom tsis txhob muaj lub resonance ntawm tus ncej thaum lub sijhawm ua haujlwm, yog li ua tiav ultra-siab ceev. Lub cav fais fab muab lub hauv paus rau kev ruaj ntseg kev ruaj ntseg thiab kev tsim cov qauv zoo ntawm txoj kev tawm.

Thaum lub sij hawm ua haujlwm ntawm cov khoom siv cav, kev co yog tsim los ntawm ntau yam kev kub ntxhov, thiab kev ua pa yog ib qho teeb meem loj ntawm qhov tsis ua hauj lwm ntawm kev ua txhua yam rotor. Rau qhov rotor system nws tus kheej, ib sab ntawm lub vojvoog ntawm qhov chaw eccentricity feem ntau yog, tshwj xeeb tshaj yog nyob rau qee yam lossis qee qhov kev ceev, qhov siab yuav nce siab, thiab txawm tias cov ncej thiab kev coj tus kheej yuav raug rhuav tshem. Qhov tshwm sim yog feem ntau tshwm sim los ntawm resonance. Yuav kom tsis txhob resonance ntawm tus ncej ntawm lub sijhawm ua haujlwm, qhov tsim ntawm txoj kab sib txuas yuav tsum kom nws qhov ceev tshaj plaws yuav tsum tsis txhob muaj qee yam ntawm qhov kev hloov tawm thiab lwm qhov kev cia siab ntawm qhov kev khiav haujlwm ntawm cov neeg ua haujlwm pib.
Daim ntawv no tsuas yog cia siab rau 20MW high-speed uas muaj kev sib tsoo muaj zog thaum muaj hluav taws xob cov cav ntoo ntawm kev lag luam ntawm cov tub lag tub luam ntev, thiab siv DyRoBeS rotor dynamics tsom software mus nqa tawm cov kev ceev nrawm thiab kev sib npaug teb ntawm qhov kev sib txuas tag nrho (tus tswv tsev thiab exciter ) ntawm lub tshuab. Chav tsev no yog lub qauv peb-kabmob uas muaj kev sib hloov ntawm 3120 ~ 5040rpm. Yuav kom ntseeg tau tias lub lag luam ruaj khov ntawm lub tsev, qhov kawg ntawm tus exciter xav nqa 300kg ntawm qhov kawg. Thaum txhim kho, lub rooj zaum ntawm rooj qhib yuav tsum tau tsa los ntawm ib qho nqi, uas yuav tsum tau muab xam rau ntawm theoretically.
