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…
Experimental analysis of the TRC benchmark system
Arati Bhattu, Svenja Hermann, Nidhal Jamia +5
The Tribomechadynamics Research Challenge (TRC) was a blind prediction of the vibration behavior of a thin plate clamped on two sides using bolted joints. The first bending mode's…
Robust and fast backbone tracking via phase-locked loops
Patrick Hippold, Maren Scheel, Ludovic Renson +1
Phase-locked loops are commonly used for shaker-based backbone tracking of nonlinear structures. The state of the art is to tune the control parameters by trial and error. In the p…
Nonlinear damping quantification from phase-resonant tests under base excitation
Florien Müller, Lukas Woiwode, Johann Gross +2
The present work addresses the experimental identification of amplitude-dependent modal parameters (modal frequency, damping ratio, Fourier coefficients of periodic modal oscillati…
Nonlinear modal testing of damped structures: Velocity feedback vs. phase resonance
Maren Scheel
In recent years, a new method for experimental nonlinear modal analysis has been developed, which is based on the extended periodic motion concept. The method is well suited to exp…
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…
