phononic crystal isolator .

enkola z’okukozesa .

1. railway track vibration isolation – akendeeza ku kutambuza okukankana okuva mu kukola eggaali y’omukka .

2. urban rail transit – ayongera ku buweerero bw’okuvuga abasaabaze .

3. layini z’eggaali y’omukka ez’amaanyi – ekendeeza ku kwonooneka kw’obukoowu ku bizimbe by’olutindo .

4. okufuga okukankana kw’ebibanda by’oku luguudo n’emikutu – enkuuma ebizimbe ebiriraanyewo n’ebintu ebikozesebwa .

ennyonnyola y’ebintu .

isolator eno ekozesa enkola ya **local resonance mechanism ya phononic crystals** okufuga obulungi okusaasaana kw’amayengo aga elastic munda mu nsengekera z’eggaali y’omukka. kituuka ku **>18db okufiirwa okuyingiza** okuyita mu 20–200hz frequency band, okutuusa okukankana kwa broadband okulungi ennyo. bw’ogeraageranya n’enkola z’embaawo ez’ekinnansi ezitengejja, egaba okulongoosa okutuuka ku **50% mu kukendeeza ku kukankana** ate nga kimalawo ddala obulabe bw’okumenya kw’enkuba —okuwa eky’okugonjoola eky’omulembe oguddako nga kigatta omulimu ogw’oku ntikko n’okweraliikirira okw’obukuumi okwa zero ku pulojekiti z’okukendeeza ku kukankana kw’eggaali y’omukka.

omulimu gw’ebintu ebikolebwa .

okufuga amayengo ga broadband:

local resonance units zigaziya elastic wave bandgap range, naddala nga zinyigiriza 20-200hz main vibration frequency band of tracks.

ensengeka y’omubiri (metamaterial structure) esobozesa obulungi bw’okukankana (vibration isolation efficiency) okusukka ) 18db, nga 40% okulongoosa mu nkola y’okukendeeza amaloboozi mu frequency enkulu.

dizayini y’obukuumi obw’omunda:

all-solid-state non-metallic resonators zimalawo obulabe bw’okumenya obukoowu bw’ensulo z’ebyuma, ekikendeeza ku nsaasaanya y’okuddaabiriza ebitundu 90%.

modular pre-installed units ziwagira okukyusa amangu, ekikendeeza ku budde bw’okuyimirira ebitundu 80%.

enkulaakulana ey’okukyukakyuka mu butonde bw’ensi:

bandgap stability ) 95% mu bbugumu eriri wakati wa -20°c~80°c, okuziyiza ebikolwa by’okugaziya ebifuuyira-okutonnya/ebbugumu.

ekipimo ky’okuziyiza okufuuyira omunnyo ) 1000h (iso 9227), esaanira embeera z’obunnyogovu ku lubalama lw’ennyanja/tunnel.

eweebwa amaanyi olw’okukola n’okuddaabiriza mu ngeri ey’amagezi:

okulondoola okutaliiko waya ku mbeera ya resonance unit kusobozesa digital twin management of vibration suppression efficiency.

omuwendo gw’emirimu .

tekinologiya omukulu: ensengeka ya phononic crystal local resonance .

okukankana okwawula omulimu: okufiirwa okuyingiza ’18db (en 15461 test standard)

effective frequency bandwidth: 20-200hz okufuga kwa bandgap elastic wave

obulamu bw’ebyuma: ) emyaka 30 (emigugu obukadde 100 egy’omugugu ogw’amaanyi)

ebbugumu eriri wakati w’ebbugumu: -20°c~80°c (okukyama kwa gadgap emirundi ≤3%) .

obusobozi bw’okutikka: ≥300kn/m2 obusobozi bw’okusitula mu nneekulungirivu

ekifo eky’okusaba .

urban metro: ebitundu ebikwata ku kukankana mu bitundu by’omukutu (under hospitals, laboratories)

oluguudo lw’eggaali y’omukka olw’amaanyi: okuziyiza n’okulwanyisa akabi mu kuwuuma mu bitundu by’omutala .

okukola obulungi: okukuuma obutonde bw’ensi mu ngeri ya ultra-quiet eri amakolero ga chip/optical laboratories eziriraanye tracks .

ebifo eby’obujjanjabi: okukuuma ebyuma nga mri obutayingirira micro-vibration .

pulojekiti z’okuddaabiriza: okulongoosa n’okukyusa enkola y’ebyuma ebitengejja eby’ekyuma ebitengejja.
