A study on Equivalent Linearization Method with a Weighted Averaging for Solving Undamped Non-linear Oscillators | Chapter 01 | Theory and Applications of Mathematical Science Vol. 3
In this paper, the Equivalent Linearization Method (ELM) with a weighted
averaging is applied to analyse five undamped oscillator systems with
nonlinearities. The results obtained via this method are compared with the ones
achieved by Parameterized Perturbation Method (PPM), Min-Max Approach (MMA),
Variational Iteration Method (VIM), Homotopy Perturbation Method (HPM), Energy
Balance Method (EBM), Hanormic Balance Method (HBM), 4th order Runge-Kutta
Method and the exact ones. The obtained results demonstrate that this method is
very convenient for solving nonlinear equations and also can be successfully
exerted to a lot of practical engineering and physical problems.
