Los ntawm NASA rau Chang'e: Kev Txhais Lus Hardcore Tech
Kev loj hlob ntawm lunarpob zebsimulants yog rooted nyob rau hauv cov cuab yeej cuab tam technology ntawm aerospace giants. Lub tsev ntawm NASA's classic JSC-1A lunar regolith simulant formula, Suav cov kev tshawb fawb pab pawg tau tsim cov phiaj xwm kev txhim kho: nce basalt gravel cov ntsiab lus mus rau 92%, thiab nplua -tuning ntxhia muaj pes tsawg leeg thiab particle morphology kom meej dua cov av thaj chaw ntawm lunar highlands. Qhov kev hloov kho simulant no tau siv ncaj qha rau qhov kev sim tsaws ntawm Chang'e-7. Hauv av-raws li simulations ntawm lub hli ntog, nws ua tiav kev sib cuam tshuam ntawm tus neeg tsav nkoj lub tshuab tsis siv neeg thiab txheej txheej lunar gravel, muab cov ntaub ntawv tseem ceeb rau kev sojntsuam qhov chaw ruaj khov ntawm lub hli.
Performance Metrics: Decoding Lunar "Mechanical Codes"
Lub zog tseem ceeb ntawm cov simulants no yog nyob rau hauv lawv qhov tseeb replication ntawm lub hli qhov chaw zoo li qub. Qhov ntau thiab tsawg yog tswj hwm nruj me ntsis hauv 0.1-1 hli gradation ntau yam, sib piv rau kev faib tawm ntawm lunar regolith (Lub hli saum npoo weathered txheej). Qhov tseem ceeb tshaj plaws, los ntawm kev ua kom zoo dua qhov kev ua kom zoo dua, cov khoom siv lub kaum sab xis sib txhuam ruaj khov ntawm 35℃- zoo kawg nkaus simulating lub zog shear thiab bearing yam ntxwv ntawm gravel txheej nyob rau hauv lub hli qis-gravity tej yam kev mob. Qhov no txhais tau hais tias cov kev ntsuam xyuas tseem ceeb xws li lunar rover obstacle traversal thiab tsaws ceg cuam tshuam kev sim tuaj yeem tawm tswv yim tawm tswv yim zoo ib yam rau lub hnub qub nyob hauv lub ntiaj teb lub chaw soj ntsuam, txo qhov kev pheej hmoo thiab nqi ntawm qhov chaw ua haujlwm.
Kev nthuav dav kev lag luam: Los ntawm Kev Xeem Aerospace mus rau Nrov Science
Tshaj li aerospace, lunar regolith simulants tau nkag mus rau pej xeem saib. Hauv cov ntawv thov kev lag luam, qhov chaw -themed chaw ua si thiab cov tsev cia puav pheej tshawb fawb tau tshwm sim raws li qhov xwm txheej tseem ceeb-Shanghai Astronomy Tsev khaws puav pheej, piv txwv li, tau yuav 200 tons ntawm cov khoom siv los ua nws thaj chaw "lunar surface" exhibition. Thaum cov neeg tuaj xyuas nkag mus rau qhov simulant- npog hauv av, qhov kev ntxhib los mos ntawm cov khoom hauv qab taw thiab taug kev tsis kam ua kom pom qhov tseeb ntawm lub hnub qub. Qhov kev paub dhau los no ua rau kev tshawb nrhiav nyob deb ntawm lub hnub tuaj yeem pom tau, txuas ntxiv tus nqi ntawm kev txiav- thev naus laus zis rau hauv kev kawm txuj ci.
