非线性惯性力通过密频内共振导致的响应饱和现象

Response Saturation Caused by a Nonlinear Inertia via IRCF (Internal Resonance due to Closely Spaced Natural Frequencies)

考察一种典型的非线性惯性力通过密频内共振导致的响应饱和现象，简明地揭示了响应饱和现象的一系列典型特点。

In this paper, we investigate the response saturation caused by a typical nonlinear inertia via IRCF, reveal some typical characteristics of response saturation in simple and explicit form, and especially demonstrate that the upper threshold of excitation level associates with the instability of saturate response through Hopy bifurcation.
