Ngokweengxelo, uNissan ulungiselele isisombululo esilula se-acoustic kwimodeli yayo ye-2022.

Iinjineli ze-Acoustic zinezixhobo ezahlukeneyo zokukhetha kuzo ukunciphisa ingxolo, ukungcangcazela, kunye nobungqwabalala (NVH) ezimotweni. Nangona kunjalo, ukhetho lwabo luhlala luzisa ubunzima obunokulinganiswa-onyukayo. Ngethuba lenkqubo yophuhliso, imoto entsha inokongeza ngokulula iikhilogram ezili-100 okanye ngaphezulu ngenxa yokusetyenziswa kwezinto ezithintela ukuthuthumela, izithintelo ezibonisa ukukhanya kunye nezandi, ezifana nokugqithisa, i-foam efakwe, kunye neglasi engenakuvakala.

Ngexesha lokugxininisa kwi-lightweight, abaphandi bezinto eziphathekayo bajonge phambili kwintuthuko entsha ukuze baphumelele i-NVH-weight battle. Izinto ezibizwa ngokuba yi-metamatadium zibonelela ngamathemba amahle ngenxa yeendleko zabo eziphantsi xa kuthelekiswa nezisombululo ze-NVH zemveli.

I-metamaterial medium yimathiriyeli eyenziweyo ehlanganisiweyo ye-macroscopic kunye nesakhiwo se-honeycomb ene-dimensional ezintathu. Ngenxa yentsebenziswano yendawo phakathi kwamacandelo eyunithi, inokubonelela ngokusebenza okugqwesileyo ekucinezeleni okanye ekuhambiseni amaza omsindo angafunekiyo.

Ukusukela ngo-2008, abakwaNissan bebephanda kakhulu ngeemetamatadium. Kwi-2020 Consumer Electronics Show, uNissan ubonise le metamaterial okokuqala kwaye wathi uya kusebenzisa le nto ukunciphisa i-NVH kwi-2022 entsha ye-Ariya yemoto yombane.

USusumu Miura, injineli yezixhobo eziphezulu zakwaNissan, uthe isiphumo sokugquma kwesandi sale metamatiya sinokufikelela ngokuphindwe kane kunezisombululo zemveli. Njengesakhiwo esilula se-mesh esongelwe kwifilimu yeplastiki, le nto inokunciphisa ingxolo ye-broadband ye-500-1200Hz, edla ngokuphuma kwindlela okanye kwinkqubo yokuhambisa. Ividiyo ibonisa ukuba le metamaterial inokunciphisa ingxolo yangasemva kwi-cockpit ukusuka kwi-70dB ukuya ngaphantsi kwe-60dB. Inkampani ithi xa kuthelekiswa neenkqubo zokunciphisa i-NVH ezikhoyo, iindleko zale nto ziphantsi, okanye ubuncinane zilingana. AbakwaNissan abakamxeli umboneleli wabo weemetamatadium.
