摘要: Subharmonic oscillations of order one-half for a single-degree-of-freedom system with quadratic, cubic, and quartic nonlinearities under parametric excitation are investigated. Two approximate methods (multiple scales generalized synchronization) used comparison. The modulation equations (reduced equations) the amplitudes phases obtained. Steady-state solutions (periodic solutions) their stability determined. Numerical carried out, graphical representations results presented discussed. obtained by two in excellent agreement.
