【Abstract】 In this paper, by applying the stroboscopic method for strongly nonlinear systems and by suitably changing its formulas, the solution of primary resonance and subharmonic resonance of the strongly nonlinear system x+αx+βx~3+γx~5=ε(-μx+δcosΩt) were studied, and the comparisons betwee(?) the results obtained by our method and those by numerical integral were given.更多还原
