Internal resonance of a flexible beam in a spatial tethered system

As one of important characteristics of the nonlinear system containing the quadratic or cubic nonlinearity, the internal resonance between the system's modes may occur and affect the nonlinear properties of the system. In this paper, the internal resonance conditions of the spatial flexible beam suspended by two springs in a spatial on-orbit tethered system are obtained based on the method of multiple scales firstly. And then, the effects of the...
