Abstract
This paper describes the interactions between different modes of a nonlinearly coupled cyclic system with three masses per segment, subject to a multi-harmonic excitation. The nonlinear coupling is based on the Coulomb friction law to enable the energy transfer between different modes. The calculation of the friction force further operates without any additional state and can be determined solely by the modal deflections. The aim is to demonstrate the phenomenon of multi-resonances and study the consequences on the energy content of the different modes. Special attention is paid to the relationship of the underlying eigenfrequencies. By varying the physical mass and stiffness parameters, different scenarios are created and investigated. In the examples shown, the case of two interacting modes is referred to understand the basic physical principles.
