Abstract

In this project nonlinear oscillating systems are investigated. The nonlinearity is caused by the effect of large deformations (geometrical nonlinearity) or by physical effects, like friction. A designated target is after a nonlinear modal analysis (for example on the basis of NNMs) a model reduction on the isolated nonlinear mode. Limitations for this approach are given by the nonlinear modal analysis.
