Predictive design of impact absorbers for mitigating resonances of flexible structures using a semi-analytical approach
Timo Theurich, Alexander F. Vakakis, Malte Krack
Analytical conditions are available for the optimum design of impact absorbers for the case where the host structure is well described as rigid body. Accordingly, the analysis reli…
Development of a Fully-Coupled Harmonic Balance Method and a Refined Energy Method for the Computation of Flutter-Induced Limit Cycle Oscillations of Bladed Disks with Nonlinear Friction Contacts
Christian Berthold, Johann Gross, Christian Frey +1
Flutter stability is a dominant design constraint of modern gas and steam turbines. To further increase the feasible design space, flutter-tolerant designs are currently explored,…
On the computation of the slow dynamics of nonlinear modes of mechanical systems
Malte Krack, Lars Panning-von Scheidt, Jörg Wallaschek
A novel method for the numerical prediction of the slowly varying dynamics of nonlinear mechanical systems has been developed. The method is restricted to the regime of an isolated…
Reliability optimization of friction-damped systems using nonlinear modes
Malte Krack, Sebastian Tatzko, Lars Panning-von Scheidt +1
A novel probabilistic approach for the design of mechanical structures with friction interfaces is proposed. The objective function is defined as the probability that a specified p…
An efficient method for approximating resonance curves of weakly-damped nonlinear mechanical systems
Alwin Förster, Malte Krack
A method is presented for tracing the locus of a specific peak in the frequency response under variation of a parameter. It is applicable to periodic, steady-state vibrations of ha…
