Hauv thaj chaw ntawm kev tsim cov cuab yeej siv tshuab siab, qhov twg txawm tias micron-level vibrations tuaj yeem ua rau tsis zoo ntawm kev tsim khoom, lub luag haujlwm ntawm granite damping kev ua tau zoo tau tshwm sim ua qhov kev hloov pauv. Tsis ntev los no kev sim vibration ua los ntawm cov tuam txhab tsim khoom hauv tsev thiab cov koom haum tshawb fawb kev lag luam tau lees paub tias kev ua kom zoo dua granite cov yam ntxwv damping tuaj yeem txo qhov kev co machining, yog li ua rau cov khoom muaj txiaj ntsig ntawm cov khoom muaj txiaj ntsig siab txog li 15% txog 20%. Qhov kev tawg no tau teeb tsa los ua kom nrawm dua ntawm Tuam Tshoj txoj kev lag luam precision machining thiab muab kev txhawb nqa kev siv tshuab zoo rau kev hloov pauv hauv tsev ntawm cov cuab yeej siv tshuab siab.
Cov cuab yeej siv tshuab ua haujlwm siab yog cov khoom siv tseem ceeb rau kev tsim cov khoom tseem ceeb hauv cov lag luam xws li semiconductors, lub zog tshiab, aerospace thiab automotive. Thaum lub sijhawm ua haujlwm, kev co uas tsim los ntawm cov cuab yeej siv tshuab nws tus kheej, cov cuab yeej txiav thiab kev sib cuam tshuam ntawm cov khoom ua haujlwm feem ntau ua rau qhov chaw tsis zoo, qhov sib txawv ntawm qhov ntev thiab txawm tias cov cuab yeej hnav, cuam tshuam ncaj qha rau qhov kev tsim nyog ntawm cov khoom tiav. "Rau cov xwm txheej ua haujlwm ua haujlwm siab heev uas xav tau qhov tseeb submicron, kev tswj kev co yog qhov tseem ceeb tshaj plaws," Li Ming, tus kws ua haujlwm laus ntawm Tuam Tshoj Precision Machinery Industry Research Institute hais. "Cov cuab yeej siv tshuab hlau cam khwb cia ib txwm muaj peev xwm damping tsawg, ua rau nws nyuaj rau ua kom tau raws li qhov xav tau ntawm kev tsim khoom niaj hnub no."
Nyob rau hauv qhov teeb meem no, granite tau maj mam hloov cov hlau cam khwb cia ua cov khoom siv zoo tshaj plaws rau cov cuab yeej siv tshuab siab thiab cov rooj ua haujlwm vim nws cov khoom zoo heev. Granite ntuj muaj qhov nyuaj siab, coefficient nthuav dav thermal qis thiab kev tiv thaiv kev hnav zoo, thiab nws cov qauv sab hauv tshwj xeeb muab nws cov kev ua haujlwm damping zoo dua - qhov zoo tseem ceeb uas cov hlau cam khwb cia tsis tuaj yeem sib piv. Txhawm rau tshawb nrhiav tag nrho cov peev xwm ntawm granite damping hauv kev ua kom zoo dua qub, ib pab pawg tshawb fawb ua ke uas muaj cov tuam txhab lag luam thiab cov tsev kawm ntawv tau ua ntau qhov kev sim vibration.
Qhov kev sim no tau ua rau ntawm lub chaw ua haujlwm machining 5-axis ultra-precision uas muaj lub hauv paus granite, nrog rau kev tsom mus rau kev ntsuas qhov kev co ntawm lub cuab yeej tshuab thaum lub sijhawm txiav cov titanium alloy thiab cov khoom siv aluminium alloy muaj zog heev. Pab neeg tau sim thawj zaug qhov kev co thiab zaus ntawm lub hauv paus hlau cam khwb cia nyob rau hauv tib cov txheej txheem ua haujlwm, tom qab ntawd hloov nws nrog lub hauv paus granite uas tau dhau los ntawm kev kho tshwj xeeb damping optimization thiab ua qhov kev sim sib piv. Cov txiaj ntsig ntawm kev sim qhia tau hais tias lub hauv paus granite txo qhov kev co ntawm lub cuab yeej tshuab los ntawm 40% txog 50% hauv 50 Hz txog 2000 Hz zaus, uas yog qhov tseem ceeb ntawm kev co zaus uas cuam tshuam rau kev ua haujlwm precision.
"Lub hauv paus ntawm kev ua kom zoo dua ntawm kev ua kom granite damping muaj ob yam: kev xaiv cov khoom siv thiab kev siv tshuab tom qab ua tiav," piav qhia Wang Tao, tus thawj coj kev tshaj lij ntawm Shandong Xinhua Granite Precision Components Co., Ltd., ib tus neeg koom nrog hauv kev sim. "Peb tau xaiv cov pob zeb granite uas muaj cov khoom sib xws thiab cov porosity sab hauv qis, thiab tom qab txiav precision thiab kev kho laus, peb tau ua kom zoo dua ntawm kev ua kom damping los ntawm kev hloov kho qhov chaw thiab cov qauv damping embedded. Cov ntaub ntawv xeem kev co tau lees paub tag nrho tias cov kev ntsuas no tuaj yeem nqus thiab tshem tawm cov kev co machining, zam kev cuam tshuam ntawm resonance rau qhov zoo ntawm kev ua tiav."
Qhov kev siv tau zoo ntawm cov thev naus laus zis granite damping zoo tshaj plaws yog qhov zoo tshaj plaws. Ib lub tuam txhab tsim khoom siv hauv Shanghai tau siv cov thev naus laus zis no rau nws cov kab tsim khoom siv cav. Tom qab ib hlis ntawm kev sim ua haujlwm, cov txiaj ntsig ntawm crankshafts thiab camshafts tau nce ntxiv los ntawm 82% mus rau 98%, thiab qhov roughness ntawm qhov chaw tau txo qis los ntawm Ra 0.8 μm mus rau Ra 0.4 μm, ua tau raws li cov qauv zoo ntawm cov cav tsheb siab. "Kev txo qis ntawm cov khoom tsis zoo tsis yog tsuas yog txiav cov nqi tsim khoom xwb tab sis kuj ua rau lub voj voog tsim khoom luv dua, coj cov txiaj ntsig kev lag luam tseem ceeb rau lub tuam txhab," Zhang Wei, tus thawj coj tsim khoom ntawm lub tuam txhab tsim khoom hais.
Cov neeg ua haujlwm hauv kev lag luam tau taw qhia tias kev siv cov thev naus laus zis granite damping performance optimization technology zoo yog ib qho piv txwv ntawm kev sib koom ua ke ntawm cov khoom siv thiab kev ua haujlwm precision. Nrog rau kev nce qib ntawm cov thev naus laus zis xws li AI thiab digital twins, kev kuaj kev co thiab kev ua kom zoo dua ntawm cov khoom granite kuj tseem yuav txav mus rau kev txawj ntse. Yav tom ntej, cov tuam txhab lag luam tuaj yeem kho cov kev ntsuas damping ntawm cov hauv paus granite hauv lub sijhawm tiag tiag raws li cov ntaub ntawv machining sib txawv, cov txheej txheem thiab cov kev xav tau precision los ntawm cov txheej txheem saib xyuas ntse, ua tiav kev tswj hwm kev co tus kheej thiab meej.
Lub Koom Haum Kev Lag Luam Tshuab Tuam Tshoj tau tshaj tawm cov ntaub ntawv qhia tias kev thov ua lag luam rau cov cuab yeej siv tshuab siab nrog cov khoom granite loj hlob ntawm tus nqi ntawm 25% ib xyoos. Kev ua kom zoo dua ntawm kev ua haujlwm damping granite yuav nthuav dav ntxiv cov xwm txheej ntawm daim ntawv thov ntawm granite hauv kev lag luam cuab yeej siv tshuab, tsis yog tsuas yog hauv cov chaw machining ultra-precision tab sis kuj tseem nyob rau hauv cov tshuab ntsuas sib koom tes, cov khoom siv ua laser thiab lwm yam khoom siv siab. Qhov no yuav pab Tuam Tshoj txoj kev lag luam cuab yeej siv tshuab tawg los ntawm kev txwv kev tswj hwm qhov tseeb thiab txhim kho nws qhov kev sib tw thoob ntiaj teb.
"Kev kuaj kev co yog lub hauv paus rau kev ua kom zoo dua ntawm kev ua haujlwm ntawm granite, thiab kev txhim kho ntawm kev ua haujlwm yog lub hom phiaj kawg ntawm kev tsim kho tshiab," Chen Hong, tus xibfwb ntawm Tsev Kawm Ntawv Mechanical Engineering ntawm Tsinghua University hais. "Yav tom ntej, peb yuav txuas ntxiv mus tshawb nrhiav ntxiv txog cov txheej txheem damping ntawm granite, tsim cov txheej txheem ua kom zoo dua thiab cov txheej txheem sim, thiab pab txhawb ntxiv rau kev txhim kho zoo ntawm Tuam Tshoj txoj kev lag luam tsim khoom raug."
Ua ib yam khoom tseem ceeb rau cov khoom siv high-end, granite ua lub luag haujlwm tseem ceeb hauv kev lag luam precision machining. Kev tshawb pom tshiab hauv kev siv tshuab damping performance optimization, uas tau txheeb xyuas los ntawm kev sim kev co, yuav ua rau muaj zog tshiab rau hauv kev txhim kho ntawm Tuam Tshoj txoj kev lag luam tshuab thiab pab cov tuam txhab tsim khoom hauv tsev siab dua kom ua tiav txoj hauv kev zoo tshaj plaws rau kev lag luam thoob ntiaj teb high-end.
