Abstract

The Hamiltonian-based frequency formulation has been hailed as an unprecedented success for it gives a straightforward insight into a complex nonlinear vibration system with simple calculation. This paper gives a systematical analysis of the formulation, and two simplified formulations are suggested. The cubic-quintic Duffing oscillator is used as an example to show extremely simple calculation and remarkable accuracy. It can be used as a paradigm for many other applications, and the one-step solving process has cleaned up the road of the nonlinear vibration theory.

非线性振动系统的简化哈密顿频幅公式

基于哈密顿的频率公式被誉为前所未有的成功，因为它以简单的计算直观地洞察了复杂的非线性振动系统。本文对该配方进行了系统分析，并提出了两种简化配方。以三次五次Duffing振荡器为例，计算简单，精度高。它可以作为许多其他应用的范例，一步求解过程清理了非线性振动理论的道路。
