✦ Synopsis


This paper deals with an approximate method of analysis of strongly non-linear autonomous vibrating systems with many degrees of freedom. The approximate equations for amplitude and phase are obtained by a generalized averaging method using the generalized harmonic functions. These functions are also periodic and are exact solutions of strongly non-linear differential equations. The case in which internal resonance may occur can be treated without difficulty. Results of the application of the method to coupled generalized van der Pol oscillators with a strong static non-linearity are shown and compared with other numerical results to demonstrate the validity of the approach.

A power-series method is presented for the analysis of a conservative strongly non-linear two-degree-of-freedom (d.o.f.) system with cubic non-linearity. The method is based on transforming the time variable into an harmonically oscillating time whereby the governing di!erential equations become wel

The hierarchical "nite-element (HFEM) and the harmonic balance methods (HBM) are used to investigate the geometrically non-linear free and steady-state forced vibrations of uniform, slender beams. The beam analogue of von KaH rmaH n's non-linear strain}displacement relationships are employed and the
