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 als

โฆ Synopsis
Free oscillations of a non-linear system having two weakly coupled degrees of freedom in which an internal resonance may occur are treated with a modified version of the K-B-M averaging method. The method presented permits one to obtain a first approximation of the solution very easily in comparison with the perturbation techniques and with the method of multiple scales that have been used to date to solve the same problem. As an example the free oscillations of a system having quadratic non-linearities are treated. This system represents a large number of physical phenomena as mentioned in the paper and the references .

The problem of decoupling a class of non-linear two degrees of freedom systems is studied. The coupled non-linear differential equations of motion of the system are shown to be equivalent to a pair of uncoupled equations. This equivalence is established through transformation techniques involving th
