Применение нового математического аппарата «Одномерные спектральные портреты матриц» к решению проблемы аэроупругих колебаний решеток лопастей

Abstract

Анализ возможностей существующих стандартных программ для определения спектров несимметричных матриц, сопутствующих задачам динамической устойчивости в аэроупругости. Особенность изгибно-крутильного флаттера крыла с кратными частотами вблизи границы флаттера. Решение с помощью дихотомии задач о флаттере и перегрузке лопаток турбины с огромным спектром частот.
