VIBRATSION KONVEYER DINAMIK PARAMETRLARINI KO‘P MEZONLI OPTIMALLASHTIRISH ALGORITMINI ISHLAB CHIQISH
Abstract
Ushbu maqolada vibratsion konveyerlarning dinamik parametrlarini ko‘p mezonli optimallashtirish algoritmini ishlab chiqish masalasi ko‘rib chiqilgan. Vibratsion konveyer ish samaradorligi tebranish amplitudasi, chastotasi, tebranish trayektoriyasining yo‘nalishi, ishchi organning massasi, elastik tayanchlarning bikrligi, so‘ndirish koeffitsiyenti va tashilayotgan materialning fizik-mexanik xususiyatlariga bog‘liq. Mazkur parametrlarni alohida-alohida tanlash ko‘pincha unumdorlikning ortishi bilan energiya sarfi, dinamik yuklanishlar va konstruktiv elementlarning charchashga chidamliligi o‘rtasida ziddiyatlarni keltirib chiqaradi. Shu sababli tadqiqotda konveyerning unumdorligini oshirish, energiya sarfini kamaytirish, tebranish amplitudasini belgilangan chegaralarda saqlash va mexanik tizimdagi dinamik yuklanishlarni pasaytirishga yo‘naltirilgan ko‘p mezonli optimallashtirish yondashuvi taklif etiladi. Tadqiqot metodologiyasi vibratsion tizimning matematik modelini shakllantirish, boshqariladigan parametrlarni belgilash, maqsad funksiyalarini normallashtirish, cheklovlarni hisobga olish va Pareto-optimal yechimlar to‘plamini aniqlash bosqichlarini qamrab oladi. Taklif etilayotgan algoritmda dastlabki parametrlar diapazoni aniqlanadi, ruxsat etilgan yechimlar fazosi shakllantiriladi, nomzod yechimlar baholanadi va o‘zaro ustun bo‘lmagan yechimlar asosida maqbul parametrlar majmuasi tanlanadi. Algoritmning amaliy ahamiyati shundan iboratki, u vibratsion konveyerlarni loyihalash va sozlashda faqat bitta ko‘rsatkichni emas, balki unumdorlik, energiya samaradorligi, dinamik barqarorlik va konstruktiv ishonchlilikni birgalikda hisobga olish imkonini beradi.
