2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Cov ntawv qhia no yuav qhia koj yuav ua li cas tsim Temcor-style dome siv tsuas yog me ntsis ntawm kev ua lej.

Feem ntau ntawm cov ntaub ntawv hauv qhov kev qhia no tau khaws los ntawm TaffGoch qhov kev thim rov qab-kev tsim kho ntawm txoj kev faib ua haujlwm qub Amundsen-Scott South Pole Station, yog li ua tsaug ntau rau nws!

Qhov txiaj ntsig tseem ceeb ntawm Temcor domes yog lawv cov lej tsis sib xws tshwj xeeb - nws nce cov lej suav nrog ntau zaus, tsis zoo li Duncan Stuart qhov niaj zaus triacontahedral geodesic daim phiaj (Txoj Kev 3*), tab sis qhov tshwm sim zoo li ntau dua.

Txhawm rau kom yooj yim, zaus ntawm lub dome peb tab tom ua yog 14, yog li cov chord yam tuaj yeem hla kev txheeb xyuas TaffGoch's Temcor qauv.

Tus Inventor 2016.ipt suav nrog qhov kawg ntawm kev qhia.

*Hloov tshiab*

Kuv tau piav qhia Txoj Kev 4 raws li Duncan Stuart qhov tsis tu ncua triacontahedral geodesic daim phiaj, tab sis nws tsis yog. Txoj hauv kev tau tsim los ntawm Christopher Kitrick, leej twg, hauv nws phau ntawv xyoo 1985, "Geodesic Domes", piav qhia nws kev tsim kho. Ib qho ntxiv, hauv nws daim ntawv 1990, "Kev Sib Koom Ua Ke rau Chav I, II & III Geodesic Domes", nws qhia txog 8 lwm txoj hauv kev, ib ntawm lawv yog Duncan Stuart Txoj Kev 3, lwm qhov nws tus kheej "Txoj Kev 4", thiab, ua rau xav tsis thoob. txaus, ib txoj hauv kev sib piv rau Temcor's, uas nws hu ua "Method aa" (Kauj Ruam 7 qhia tau tias Temcor hloov kho li cas "Method aa"). Hauv kev qhia yav tom ntej, Kuv yuav piav qhia kev tsim cov txheej txheem uas tau hais tseg hauv daim ntawv tom kawg.

Kauj Ruam 1: Tus Neeg Siv Khoom

Ua ntej peb pib tsim lub dome, nkag mus rau qhov ntsuas pom:

Phi - Golden Qhov Piv Txwv. Txhais raws li ((1+√5/) 2

Circumsphere - Qhov no yog qhov ncig ntawm dodecahedron, txhais tias yog ((Phi*√3)/2)

PatternAngle - Qhov no yog lub hauv paus ntawm lub dodecahedron. Txij li qhov zaus ntawm peb lub dome yog 14, peb faib lub kaum sab hauv nruab nrab los ntawm ib nrab zaus, hauv qhov no, 7.

Kauj Ruam 2: Sketching Golden Rectangle

Pib kos duab ntawm lub dav hlau YZ, tom qab ntawd tsim peb lub kaum plaub lub kaum plaub raws li qhia, xa mus rau daim duab sau tseg rau cov ntaub ntawv ntxiv piav qhia txog kev tsim Golden Rectangle.

Kauj Ruam 3: Tsim kom muaj Golden² Rectangle

Tsim lub dav hlau ua haujlwm siv X axis thiab kab hais qhia hauv thawj daim duab, tom qab ntawd pib lwm daim duab ntawm lub dav hlau ua haujlwm no. Ua lub hauv paus duab plaub lub kaum sab xis pib los ntawm keeb kwm, tom qab ntawd muab cov duab plaub raws li pom hauv daim duab thib peb.

Kauj Ruam 4: Tsim 2v Triacon Triangle

Tam sim no peb muaj txhua qhov duab peb xav tau, tsim thaj tsam thaj tsam hauv daim duab thib ob siv yam twg los xij uas koj nyiam. Kuv xaiv ua daim duab 3D, tab sis kos rau lwm lub dav hlau ua haujlwm yuav ua haujlwm ib yam nkaus.

Kauj Ruam 5: Tsim Txoj Kev Sib Hloov Dav Hlau

Pib lwm qhov kos duab ntawm thawj lub dav hlau ua haujlwm ("Dav Hlau Ua Haujlwm 1") koj tsim, npaj cov ces kaum ntawm Golden² Rectangle, tom qab ntawv txuas cov ntsiab lus no thiab keeb kwm los tsim lub hauv paus nruab nrab ntawm 2v triacontahedron. Faib nws los ntawm ib nrab zaus ntawm lub dome, zoo li yog tias koj tab tom pib Txoj Kev 2 tawg. Muab cov ntsiab lus tso rau ntawm qhov nruab nrab ntawm cov chords.

Tawm ntawm daim duab, tom qab ntawd tsim lub dav hlau siv ib qho ntawm cov chords thiab nws qhov nruab nrab, raws li qhia hauv daim duab thib ob. Tom qab ntawd, tsim lwm lub dav hlau ua haujlwm siv "Lub kaum rau dav hlau ncig ntug". Xaiv Lub Dav Hlau Ua Haujlwm 1 thiab ib qho ntawm cov kab kev tsim kho tau qhia hauv nruab nrab sab xis thiab sab laug daim duab. Txais lub kaum sab xis ntawm 90 degrees, txwv tsis pub seem ntawm kev faib tawm yuav tsis zoo. Rov ua cov txheej txheem siv cov seem ntawm cov chords thiab cov kab tsim kho kom tau txais txiaj ntsig hauv daim duab qis dua.

Kauj Ruam 6: Tsim Kev Nkag Nkag Nkag Nkag thiab Tsim Kev Sib cais

Pib kos duab 3D, tom qab ntawd tsim txoj kab nkhaus sib tshuam siv lub dav hlau ua haujlwm uas koj nyuam qhuav tsim thiab thaj ua rau thaj, tsim cov kab uas pom hauv daim duab saum toj kawg nkaus.

Kos kab ua ke kom txog rau qhov kawg ntawm txoj kab nkhaus sib tshuam raws li qhia hauv Duab 2. Ua kom lawv txhua tus sib npaug rau lub vojvoog ntawm lub dome. Kos cov chords koom nrog cov kab uas nyob ntawm txoj kab nkhaus sib tshuam. Txuas ib qho geometry uas zoo li ze txaus los tsim ib daim duab peb sab ntawm kev faib tawm. Xa mus rau tom ntej 10 cov duab uas chords tsom iav hla txoj kev sib tshuam dav hlau - lawv tuaj yeem piav qhia nws zoo dua li cov lus yooj yim.

Kauj Ruam 7: Ua kom tiav lub Dome

Tsim kom Thicken/Offset ntawm kab hauv qab, tshem tawm ob kab kawg ntawm peb tog. Txawv qhov OffsetSrf tshiab 6 zaug, lossis ((Zaus = 14)/2) -1. Nkaum qhov OffsetSrf, plooj qhov chaw ua qauv, tom qab ntawd tsom iav qhov stitched nrog YZ Plane. Tsim cov dav hlau ua haujlwm so ntawm lub kaum sab xis ntawm daim duab peb sab saum toj, raws li qhia hauv Duab 6. Txiav qhov chaw sib dhos thiab tsom iav siv cov dav hlau ua haujlwm tshiab no, tom qab ntawd txuas cov seem uas seem ua ke. Txawv qhov kawg saum toj no hla Z axis, tom qab ntawv ua cov txheej txheem kawg no ua ke, thiab koj ua tiav!

Kauj Ruam 8: Txheeb Chords

Yog li, peb lub dome tiav, tab sis cia saib seb cov lej sib phim nrog TaffGoch tus qauv:

Mus los ntawm qhov tsis siv, nws zoo li lawv yog qhov sib tw zoo tshaj plaws!

Dividing chord lengths los ntawm 1000, peb tuaj yeem pom meej meej qhov kev sib tham zoo nrog chord yam ntawm TaffGoch tus qauv, ntxiv rau hneev taw hneev taw thiab lwm yam yam.
