MAQOLA ANNOTATSIYASI

Ushbu maqolada Saralash tepaligi balandligini hisoblashda yomon sharoitni inobatga olgan holda eng yomon yugurak sifatida vagon turini tanlash tahlili olib borilgan. Saralash tepaligidan tushayotgan yarim ochiq vagonning harakati tahlil qilingan. Yarim ochiq vagonga ta’sir qiluvchi kuchlar tasnifi to‘liq yoritilgan. Qarshi esayotgan havo oqimi ta’sirida yarim ochiq vagonning old va ichki orqa devoriga ta’sir etayotgan aerodinamik bosim va siljish masofasi hisob ishlari amalga oshirilgan. Saralash tepaligida yopiq va yarim ochiq vagonlar harakat tezliklari solishtirilganda ko‘rish mumkinki saralash tepaligining tezlashtiruvchi uchastkasi o‘zgarishi natijasida, tezlashuvchi uchastka oxirida yarim ochiq vagon tezligini yopiq vagonga nisbatan 34,6 %ga kam ekanligi aniqlandi. Qarshi esgan shamol tezligini ta’sirini baholashda SOLIDWORKS Flow simulation paket dasturidan foydalanib natijalar olindi, bu natijalarning aniqliligini yanada oshirishni ta’minlab berdi. Vagonga ta’sir etayotgan havo oqimining maksimal aerodinamik bosimi 101,602 KPani tashkil etadi. Saralash tepaligini balandligini hisoblash jarayonlarida yarim ochiq vagonga ta’sir etadigan havo oqimini faqat old tomoniga ta’siri inobatga olib ketilgan biroq, bo‘sh yarim ochiq vagon ichida hosil bo‘ladigan turbulent havo oqimi va vagon oxirgi ko‘ndalang devoriga aerodinamik ta’sirlar vujudga kelishi modellashtirish jarayonlarida qayd etildi.
