摘要
针对工程实际中存在的duffing非线性系统,采用了多尺度法进行研究。首先建立了考虑duffing振子的系统非线性动力学方程,应用多尺度法得到了系统在超谐共振情况下的的幅频方程,并研究了系统的幅频曲线。结果表明:阻尼增大会对超谐共振有抑制作用,并使产生亚谐共振的频率减小。
To analyse the duffing nonlinear systems that widely existing in actual engineering,the multi-scale method is used to study in this paper.First,a nonlinear dynamic equation with duffing oscillator is established.The amplitude-frequency equation of the system under super harmonic resonance is obtained by using the multi-scale method,and the amplitude frequency curve of the system is studied in this paper.
