Abstrak
Ushbu ilmiy maqola davomida yuzaga keladigan muammolarni ko'rib chiqadi
tekislik bosimi zarba to'lqinining elastik dumaloq silindrsimon paneli bilan o'zaro ta'siri.
Ideal suyuqlikda silindrsimon ekranga biriktirilgan silindrsimon panel mavjud.
Yupqa sayoz qobiqlar nazariyasiga ko'ra, panelning ko'ndalang tebranishlari
cheklangan burilishlarning taniqli tenglamalari bilan tavsiflanadi. Muammosi
kuchsiz zarba to'lqini ta'sirida elastik panelning chiziqli bo'lmagan harakati a
murakkab muammo. Muammoni soddalashtirish uchun aks ettirilgan va radiatsiya qilingan bosim
to'lqinlar diffraktsiyani hisobga olmagan holda taxminan aniqlanadi
chegara qirralari. Ushbu soddalashtirishlar asosida a uchun asosiy formulalar
silliq silindrsimon qobiq hosil bo'ladi. Maple-17 dasturidan foydalanib, chiziqli bo'lmagan
ideal suyuqlikda joylashgan silindrsimon panel harakatining differensial tenglamalari
raqamli hal qilinadi. Olingan natijalar shuni ko'rsatadiki, paneldagi tebranishlar
ideal suyuqlik aperiodikka yaqin. Bu uning yuqori damping bilan bog'liq.
