Applications of He’s Amplitude-Frequency Formulation to the Free Vibration of Strongly Nonlinear Oscillators
In this paper, He's amplitude-frequency formulation is used to obtain a periodic solution of a nonlinear oscillator. We illustrate that He's amplitude-frequency formulation is very effective and convenient and does not require linearization or small perturbation. The obtained results are valid for the whole solution domain with high accuracy.
متن کاملVibration Control Design for Nonlinear Systems using Frequency Response Function
A nonlinear frequency response based adaptive vibration controller is proposed for a class of nonlinear mechanical systems. In order to obtain the nonlinear Frequency Response Function (FRF), the convergence properties of the system are studied by using the convergence (contraction) theory. If the system under consideration is: 1) convergent, it directly enables to derive a nonlinear FRF for a ...

This paper deals with large amplitude oscillation of a nonlinear pendulum attached to a rotating structure. The concept of amplitude-frequency formulation and He’s energy balance method is briefly introduced, and its application for the rotational pendulum system is studied Accuracy and validity of the proposed techniques are then verified by comparing the numerical results obtained based on th...
متن کاملFrequency analysis of strongly nonlinear generalized Duffing oscillators using He's frequency-amplitude formulation and He's energy balance method
In this paper, He's Frequency-Amplitude Formulation (HFAF) and He's Energy Balance Method (HEBM) are employed to solve the generalized Duffing equation in the form of over (x, ̈) + x + α3 x3 + α5 x5 + α7 x7 + ⋯ + αn xn = 0 . For any arbitrary power of n, a frequency analysis is carried out and the relationship between the natural frequency and the initial amplitude is obtained in analytical form...
متن کاملThe Time-frequency Spectral Estimation of Nonlinear Vibration Systems
I. INTRODUCTTON The traditional methods of nonstationary signal spectral estimation are based on the assumption that on a short-time basis the signal is stationary. This has the important drawback that the length of the assumed short-time stationarity determines the frequency resolution which can be obtained. To increase the frequency resolution one has to take a longer measurement interval (wi...
