摘要
本文推广文[1]中方法于求解广泛一类强非线性振动系统,导出了适于近似定性分析和定量计算的简便公式。作为例子研究了修正的Vander Pol振子,最后给出数字Poincaré映射结果,从近似定性分析和定量计算两方面证明了本文求得的方法的有效性。
The method in [1] is generalized and applied to the solutions of a wide class of strongly nonlinear vibration systems in this paper. The easier formulas are introduced for the approximate qualitative analysis and quantitative calculation. As an example, we have studied the behavior of the revised van der Pol vibrator. At last, through displaying the results of the numerical Poincare map, the efficiency of the method presented in this paper has been evidenced from the approximate qualitative analysis and quantitative calculation.
