Abstract
As previously discussed nonlinear vibration and periodic motions of galloping cables, analytical solutions for period-m motions in a periodically forced, and quadratic nonlinear oscillator are presented first through the Fourier series solutions with finite harmonic terms, and the stability and bifurcation analyses of the corresponding period-m motions are carried out. The bifurcation trees of period-1 motions to chaos are presented for a better understanding of complex motions in such a quadratic nonlinear oscillator . Trajectories and amplitude spectrums are illustrated numerically.
