Cov khoom lag luam

Yuam kev co thiab cov resonance tshwm sim feem ntau siv hauv kev tshawb fawb engineering thiab kev tshawb fawb, xws li hauv kev tsim kho, tshuab thiab lwm yam kev tsim vaj tsev, nws yog ib qho tsim nyog yuav tsum zam kom tsis txhob muaj cov resonance tshwm sim los xyuas kom zoo ntawm engineering. Hauv qee qhov kev lag luam petrochemical, resonance phenomenon kab yog siv los ntsuas qhov ceev cov kua thiab qhov siab ua kua, yog li yuam kev vibration thiab resonance yog qhov tseem ceeb ntawm kev cai lub cev, uas muaj ntau dua thiab nrov hauv physics thiab engineering thev naus laus zis. Qhov ntsuas tau siv tuning fork vibration system raws li kev tshawb nrhiav khoom, kev siv lub zog ntawm lub tshuab hluav taws xob ntawm lub zog hluav taws xob zoo li lub zog txaus siab, thiab electromagnetic coil raws li amplitude sensor los ntsuas qhov kev sib raug zoo ntawm kev co lub zog thiab tsav quab yuam zaus, thiab kawm yuam kev tshee thiab resonance tshwm sim thiab nws txoj cai Cov.

Kev sim

1. Kawm qhov sib txheeb ntawm qhov nrawm thiab quab yuam lub zog ntawm lub tuning fork vibration system tsav los ntawm ib puag ncig sab nraud quab yuam. Kev ntsuas thiab cov phiaj xwm lawv txoj kev sib txheeb nkhaus, thiab tau txais cov zaus thiab qhov ua kom pom ntawm qhov kev co (qhov nqi no yog sib npaug ntawm tus nqi Q).

2. Ntsuas qhov kev sib txuas ntawm lub vibration thiab qhov loj ntawm lub caj npab symmetrical ntawm lub tuning diav rawg. Txais kev sib txheeb mis sib piv ntawm cov vibration zaus f (piv txwv li zaus zaus) thiab block mass m txuas rau tuning fork caj npab ntawm qhov chaw.

3. Txheeb xyuas qhov sib txawv ntawm cov khub loj ntawm cov txuas uas txuas rau lub rab nrig tuning caj npab los ntawm kev ntsuas ntsuas zaus.

4. Ntsuas cov qhov ua kom rov zoo li qub thiab lub suab sib txawv thaum lub suab sib pauv thaum hloov lub vibration qauv thiab nce damping quab yuam ntawm lub tuning diav rawg thiab ua qhov sib piv.

Phau ntawv qhia muaj cov qauv sim, cov qauv, cov lus qhia ib qib-ib-qib, thiab cov piv txwv ntawm cov txiaj ntsig sim. Thov nias Xyaum kev ua si thiab Txheej txheem kom pom cov ntaub ntawv ntxiv txog cov tshuab no.
