摘要
本文应用强非线性系统频闪法,对公式进行适当变换,求出了方程x+ax+βx^3+γx^5=ε(-μx+δcosΩt)的共振解及亚谐解存在的条件及其解析表达式,并与数值计算结果作了比较.
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.
