摘要: Abstract We study the vibrations of a string subject to planar harmonic excitation, both experimentally and theoretically. observe multiple periodic motions, non-planar (whirling), as well quasi-periodic whirling irregularly precessing oscillations when forcing frequency is near that transverse normal mode. A two-degree-of-freedom model derived, it shown these motions can be partially understood in terms completely integrable Hamiltonian system obtained damping tend zero model.
