MAQOLA ANNOTATSIYASI

Mazkur ilmiy ishda avtomobilning aerodinamik qarshilik kuchiga yuza sifatining ta’siri kichik o‘lchamdagi modellar asosida tajribaviy yo‘l bilan o‘rganilgan. Tadqiqot jarayonida 3D bosma texnologiyasi yordamida tayyorlangan avtomobil modellarining yuza sifati real avtomobil kuzovining sirt holatiga yaqinlashtirildi. Yuza sifati miqdoriy baholash uchun Ra (o‘rtacha arifmetik notekislik) va Rz (o‘rtacha maksimal notekislik balandligi) parametrlari tanlandi. O‘lchov natijalariga ko‘ra, sinov modeli va haqiqiy avtomobil yuzasi o‘rtasidagi farq Ra bo‘yicha +0,474 mkm, Rz bo‘yicha esa +2,20 mkm ni tashkil etdi. Ushbu natijalar model yuzasining real sharoitga yetarlicha yaqin ekanligini ko‘rsatadi va aerodinamik sinovlar natijalarining ishonchliligini oshiradi. Tadqiqot natijalari shuni ko‘rsatdiki, yuza silliqligining yaxshilanishi chegaraviy qatlam xususiyatlariga sezilarli ta’sir ko‘rsatib, aerodinamik qarshilik kuchining kamayishiga olib keladi.
