A sub-structuring approach for model reduction of frictionally clamped thin-walled structures
Patrick Hippold, Johann Gross, Malte Krack
Thin-walled structures clamped by friction joints, such as aircraft skin panels are exposed to bending-stretching coupling and frictional contact. We propose an original sub-struct…
A coupled FE-BE multi-scale method for the dynamics of jointed structures
Hendrik D. Linder, Johann Gross, Malte Krack
The damping of built-up structures stems largely from the microscopic dry frictional interactions in the contact interfaces. The accurate prediction of friction damping has been an…
An iteration-free approach to excitation harmonization
Patrick Hippold, Gleb Kleyman, Lukas Woiwode +6
Sinusoidal excitation is particularly popular for testing structures in the nonlinear regime. Due to the nonlinear behavior and the inevitable feedback of the structure on the exci…
Challenging an experimental nonlinear modal analysis method with a new strongly friction-damped structure
Maren Scheel, Tobias Weigele, Malte Krack
In this work, we show that a recently proposed method for experimental nonlinear modal analysis based on the extended periodic motion concept is well suited to extract modal proper…
Experimental assessment of polynomial nonlinear state-space and nonlinear-mode models for near-resonant vibrations
Maren Scheel, Gleb Kleyman, Ali Tatar +5
In the present paper, two existing nonlinear system identification methodologies are used to identify data-driven models. The first methodology focuses on identifying the system us…
A Phase Resonance Approach for Modal Testing of Structures with Nonlinear Dissipation
Maren Scheel, Simon Peter, Remco I. Leine +1
The concept of nonlinear modes is useful for the dynamical characterization of nonlinear mechanical systems. While efficient and broadly applicable methods are now available for th…
