摘    要:
首先利用多尺度法分析了Duffing-van der Pol系统在多频激励下的主共振响应,得到了该系统的一次近似解。然后利用数值方法研究了系统参数对近似解幅频曲线的影响。最后,运用奇异性理论得到了系统的全部分岔响应曲线,为这一类系统的动态分析与设计提供了理论依据。

关 键 词:多频激励  Duffing系统  vanderPol系统  分岔  奇异性理论

Abstract:
In this paper,the main resonance of nonlinear Duffing-van der Pol system to multi-frequency excitations is investigated,and the MultiScale Method is used to obtain the first-order approximate solution.Then the effects of system parameters on the frequency-amplitude curve are studied by means of numerical technology.Finally,all the bifurcation curves are obtained using the singularity theory,which provides theoretical basis for dynamic analysis and design of this kind of systems.
Keywords:multi-frequency excitation  Duffing system  van der Pol system  bifurcation  singularity theory
