Electromagnetic phom: hauj lwm, hom

Electromagnetic phom yog ib lub npe rau kev sib tsim los ua kom cov khoom siv zog (khoom) nrog kev pab los ntawm electromagnetic rog. Xws li cov cuab yeej hu ua electromagnetic mass accelerators.

Electromagnetic phom raug faib ua cov hom nram qab no:

1. Railgun - ntaus ntawv no yog ib qho kev siv hluav taws xob ntawm electrode pulse. Lub chaw ua hauj lwm ntawm cov cuab yeej no yog qhov txav ntawm qhov projectile ntawm ob lub electrodes - lub tsheb nqaj hlau - los ntawm qhov uas tam sim no ntws. Ua tsaug rau qhov no, electromagnetic phom ntawm hom no tau txais lawv lub npe - railgun. Nyob rau hauv xws li qhov tam sim no qhov chaw muaj kev cob cog rau hauv qab kev tsheb nqaj hlau, raws li ib tug tshwm sim tam sim no ntws "catch up" rau cov tsiv kwv. Lub magnetic teb yog generated nyob ib ncig ntawm tus neeg xyuas pib los ntawm kev uas tam sim no tsev, nws yog feeb meej tom qab lub mus projectile. Yog li ntawd, qhov khoom, qhov tseeb, yog tus neeg xyuas pib, uas yog muab tso rau hauv ib lub hauv paus uas sib txawv ntawm qhov tsim los ntawm cov ntsia hlau. Raws li cov kev cai ntawm physics, nyob rau hauv projectile impacts lub Lorentz quab yuam, uas yog qhia nyob rau hauv kev coj rov qab los ntawm cov kev twb kev txuas taw tes rail thiab accelerates ib tug kwv.

2. Thompson's cov phom tua kabmob electromagnetic yog huab cua loj inductive. Lub hauv paus ntawm lub induction phom raws li nyob rau hauv lub hauv paus ntsiab lus ntawm electromagnetic induction. Nyob rau hauv lub kauj ntawm lub cuab yeej tam sim no ua tam sim no, nws ua rau qhov chaw magnetic teb ntawm ib qho txawv txav. Cov cua daj cua dub yog qhov chaw nyob ib ncig ntawm cov tub ntxhais ferrite, thaum kawg uas muaj lub nplhaib. Vim hais tias ntawm cov nyhuv ntawm lub magnetic flux uas permeates lub nplhaib, muaj ib tug alternating tam sim no. Nws tsim ib lub teb chaw magnetic muaj ib qho kev coj rov qab mus rau qhov kev taw qhia winding. Lub nplhaib sib txuas nrog nws qhov kev ua si los ntawm cov lus teb rov qab ntawm kev sib tw thiab, accelerating, yoov tawm ferrite pas nrig. Qhov ceev thiab qhov tso zis hluav taws xob ntawm lub nplhaib yog ncaj qha rau ntawm lub zog ntawm tam sim no pulse.

3. Electromagnetic Gauss rab phom - sib nqus loj accelerator. Named tom qab tus neeg kawm txog zauv-tus kws tshawb fawb Karl Gauss, leej twg ua tau zoo heev rau txoj kev kawm txog cov khoom ntawm electromagnetism. Cov ntsiab keeb Gauss phom yog ib tug solenoid. Nws yog lub qhov txhab rau ntawm ib lub dielectric tube (pob tw). Ib qho khoom ferromagnetic muab tso rau hauv qhov kawg ntawm lub raj. Thaum lub sij hawm tam sim no thaum muaj hluav taws xob tam sim no tshwm sim, lub magnetic teb tshwm sim hauv lub solenoid, nyob hauv qhov kev txiav txim uas qhov projectile accelerates (nyob rau hauv cov kev taw qhia ntawm qhov chaw ntawm lub solenoid). Ntawm qhov kawg ntawm tus ncej them yog tsim, uas yog cov kev taw qhia ntawm cov ncej ntawm lub kauj, vim tias, tom qab dhau lub qhov projectile los ntawm qhov chaw nruab nrab ntawm lub solenoid, nws pib nyiam nyob rau hauv cov lus qhia rov qab (nws yog braked). Daim duab ntawm rab phom electromagnetic qhia nyob hauv daim duab.

Niaj hnub nimno kev tshawb fawb tau ua rau kev kawm tau ntawm kev siv acceleration thiab tsub zuj zuj zog ntawm lub zog, thiab kev tsim tawm ntawm impulses. Peb muaj peev xwm xav tias yav tom ntej, tib neeg yuav ntsib ib yam tshiab ntawm kev ua tsov rog - electromagnetic cannons. Yuav tsim txoj kev siv tshuab no, cov hauj lwm tseem ceeb yuav tsum muaj nyob rau txhua qhov ntawm cov leeb huab cua, nrog rau cov plhaub thiab lub hwj chim. Lub luag haujlwm tseem ceeb tshaj plaws yuav raug ntaus los ntawm cov ntaub ntawv tshiab. Yuav ua kom muaj kev zoo li no, yuav tsum tau muaj zog thiab muaj qhov sib npaug ntawm cov hluav taws xob hluav taws xob. Thiab cov high-temperature superconductors. Vim tias tsis ntev los no cov hauj lwm ntawm N. Tesla yog nrov heev, nws yuav tsum assumed tias cov yees yuav ua ke. Hauv qhov no, peb yuav pom cov phom tua kabmob uas tsis muaj zog, vim nws yuav tuaj ncaj qha ntawm cov pa.
