Nonlinear normal modes and spectral submanifolds: existence, uniqueness and use in model reduction
George Haller,Sten Ponsioen +1 more
TL;DR: In this paper, a unified approach to nonlinear modal analysis in dissipative oscillatory systems is proposed, which covers both autonomous and time-dependent systems and provides exact mathematical existence, uniqueness and robustness results.
Journal ArticleDOI
Exact model reduction by a slow–fast decomposition of nonlinear mechanical systems
George Haller,Sten Ponsioen +1 more
TL;DR: In this article, the authors derive conditions under which a general nonlinear mechanical system can be exactly reduced to a lower-dimensional model that involves only the softer degrees of freedom, called slow-fast decomposition (SFD).
Journal ArticleDOI
Model reduction to spectral submanifolds and forced-response calculation in high-dimensional mechanical systems.
TL;DR: In this paper, spectral submanifold (SSM) theory is used to extract forced response curves without any numerical simulation in high-degree-of-freedom, periodically forced mechanical systems.
Journal ArticleDOI
Automated Computation of Autonomous Spectral Submanifolds for Nonlinear Modal Analysis
TL;DR: In this paper, the smoothest nonlinear continuations of modal subspaces of the linearized system are constructed up to arbitrary orders of accuracy, using the parameterization method.
