Txoj moo

Nyob rau hauv ib lub caij nyoog uas muaj kev lag luam, cov tsev lag luam lag luam, thiab cov khoom lag luam tseem ceeb tso rau ntawm cov khoom siv hluav taws xob hauv tshuab hluav taws xob, tswj hwm huv si tau dhau los ua qhov tseem ceeb tshaj plaws. Harmonics-distortions nyob rau hauv cov hluav taws xob tam sim no los ntawm cov khoom tsis yog-linear zoo li muaj peev xwm ntau zaus, thiab coj teeb pom kev ua tsis taus, siv hluav taws xob, thiab cov nqi ua haujlwm tau zoo ntxiv. Ua ib qho kev lim dej phem (AHFS) tau tshwm sim raws li kev txiav cov teeb meem kom txo cov teeb meem no, ua kom muaj kev ntseeg siab. Cov lus qhia no yog qhov tseem ceeb rau cov tshuab hluav taws xob niaj hnub, thiab cov ntsiab lus tseeb ntawm peb cov lus nug ua haujlwm kom muaj cov lus nug uas nquag ua rau lawv cov kev hloov pauv.

Tsev hnub ci tau dhau los ua kev xaiv nrov rau kev txhim kho tsev neeg lub zog hluav taws xob vim lawv lub zog hloov zuj zus thiab siv nyiaj ntev. Lawv tuaj yeem hloov kho lub teeb rau hauv hluav taws xob, uas tsis tsuas yog txo qis cov phiaj xwm thiab txo cov peev txheej hluav taws xob hauv tsev, tab sis kuj ua raws li kev tiv thaiv ntawm ib puag ncig. Nws cov kev txhim kho hauv kev teeb tsa yooj yim thiab cov laus txheej txheem ua kom tiav tso cai rau cov tsev neeg zoo tib yam kom txais lub zog kom huv. ​

Saib xyuas txhua lub zog engineers! Nrog rau cov sij hawm tsis ntev los no kub, ntau lub chaw ua haujlwm 'phab ntsa-mounted nquag siv (ahfs) yog lawv cov nyiaj them poob haujlwm tau raug txo, lossis lawv tsuas yog tso tseg ua haujlwm zoo rau nws. Qhov tseeb, muaj cov cim ib txwm ua ntej kev poob qis hauv cov cuab yeej ua haujlwm. Kawm ob txoj kev kuaj tus kheej tuaj yeem txuag koj tus nqi kho kom zoo!

Cov teeb meem tsis zoo no yog tam sim no tshaj tawm cov teeb meem hauv tractways thiab qib siab-ceev railways, ntau li "qua ntxi. Phab ntsa-mounted cov ntxaij lim dej uas nquag (AHF) ua raws li cov tshuaj ntse ntse, tshwj xeeb raug tsim los tshawb xyuas thiab tshem tawm cov kev puas tsuaj no.

Koj puas tau hnov txog "Harmonics" hauv hluav taws xob? Yog tias tsis yog, nws yog lub sijhawm los them sai sai - vim tias cov tsis pom kev tsis sib xws tuaj yeem ua tau twj ywm eroding kev txuag, ua kom cov khoom siv ua kom puas tsuaj, thiab ua kom lub zog siv hluav taws xob. Tab sis dab tsi muaj kev sib haum xeeb, raws nraim?

Harmonics yog ib qho tseem ceeb tseem tsis tau pom feem ntau ntawm qhov tshwm sim hauv cov tshuab hluav taws xob. Lawv sawv cev rau cov distortions ntawm qhov zoo tshaj plaws Sinusoidal WaveFormform ntawm cov zaus uas yog cov zauv feem ntau ntawm cov zaus (piv txwv li 50 Hz lossis 60 HZ). Thaum muaj kev sib haum xeeb yog qhov xam tau nyob rau hauv lub zog niaj hnub, lawv txoj kev tswj tsis tau tuaj yeem ua rau muaj kev rau nyiaj txiag hnyav thiab nyiaj txiag. Kab lus no yuav tshawb txog lawv cov laj thawj, teebmeem, thiab kev pheej hmoo.
