ARRALI JINNING QIYA QOZIQLI TASHLAB BERUVCHI BARABANI VALI DIAMETRI VA ORALIQ DISKLAR SONINING MUSTAHKAMLIK HAMDA DINAMIK KOʻRSATKICHLARGA TAʼSIRINI HISOBLASH

Maqolada arrali jinning tashlab beruvchi barabani vali diametrining (34, 36 va 38 mm) hamda oraliq disklar sonining (4, 6 va 8 ta) mustahkamlik va dinamik koʻrsatkichlarga taʼsiri oʻrganilgan. Baraban val, qobiq va disklardan tashkil topgan chekli elementli model sifatida qaralgan. Disk va val orasidagi burilish bikrligi disk plastinkasi nazariyasi asosida aniqlangan. Toʻqqizta variant uchun egilish kuchlanishi, charchoq zaxirasi, egilish, kritik aylanish chastotasi va ikkinchi xususiy chastota hisoblangan. Val diametri 34 mm dan 38 mm gacha oshirilganda egilish kuchlanishi 51,0 MPa dan 37,6 MPa gacha kamaygan. Oraliq disklar sonini 4 tadan 8 taga oshirish global mustahkamlikni yaxshilamagan, biroq massani 2,6 kg ga oshirgan. Ikkinchi xususiy chastotaning qoziq qatorlari oʻtish chastotasiga (60 Hz) yaqin ekanligi koʻrsatilgan. Tadqiqot natijalariga koʻra, val diametri 36 mm va 4 ta oraliq diskdan foydalanish tavsiya etilgan.Keywords
