Анализ вынужденных колебаний системы с двумя степенями свободы, содержащей существенно нелинейный виброгаситель

Abstract

Concept of nonlinear normal modes is used to study vibrations of some elastic structures attached with single-DOF nonlinear elastic absorbers. The localized vibration modes favorable for the absorption are allocated. Sta­bility of nonlocalized modes is investigated. The forced vibrations in such systems are considered also, the principal resonances are analyzed. Forced resonances of the systems under consideration are considered too
