| Abstract | ||||
| Combinations solution of additive type to a two coupled weakly nonlinear second order differential equations which governed the motion of a two coupled nonlinear oscillator subjected to linear parametric excitation and external excitation. We determined the modulation equations in the amplitude and the phase, steady state solutions, the frequency-response equation and stability analysis of the steady state solutions by MSMS. Numerical study of the frequency-response equations and stability equations are given for different values of the parameters. Results are plotted in group of Figures. Finally discussion and conclusion are given. | ||||
