Abstrakt
A concept of the method of determining the parameters describing the damping and
the nonlinearity, which can be of physical or geometrical nature, is presented in the paper. The
main idea is explained regarding mechanical systems with one degree of freedom, however,
the method can be also employed to identification for systems with two DoF provided that the
couplings are weak and the resonances do not occur simultaneously. The analysis of stationary
resonance states can be reduced only then to the third-degree equation, which is a necessary
condition for the applicability of this method. Numerical simulations, which are carried out,
confirm the usefulness and accuracy of the method.
