Higher Approximation of Steady Oscillations in Nonlinear Systems with Single Degree of Freedom : Suggested Multi-Harmonic Balance Method
スポンサーリンク
概要
- 論文の詳細を見る
In order to obtain the higher order approximate solutions for steady oscillations of a nonlinear system, a so-called multi-harmonic balance method is suggested, for computing a number of harmonic components simultaneously. The formalization of the computation in the successive approximation is devised by applying the complex Fourier series and the general and detailed procedure is indicated clearly. Using as an example the homogeneous Duffing equation, for which an exact solution is known, the accuracy and the mechanism by which the computational errors occur are discussed. The method is fully examined generally and with regard to the technique of machine computation.
