โœฆ Synopsis

It is well known that a number of solutions may coexist in non-linear systems. Therefore, a complete solution diagram is very important in solving non-linear vibration problems in order to ensure that all possible solutions have been sought. This paper is aimed at seeking solution diagrams by means of performing parametric studies. In particular, the Incremental Harmonic Balance (IHB) method is used in the study. By introducing a parameter, this method can give solution diagrams of different non-linear dynamic systems, even with strong non-linearity. Examples of van der Pol oscillators and coupled oscillators are used to illustrate the effectiveness of the method and the importance of obtaining solution diagrams. Hopf bifurcations will also be discussed with these solution diagrams.

Non-linear phenomena in the vibration of a square plate subject to lateral forcing are studied. Starting from the dynamic analogue of the von Kaยดrmaยดn partial differential equations that govern the motion of the plate, a system of second order non-linear ordinary differential equations are derived.

The multiple scales method, developed for the systems with small non-linearities, is extended to the case of strongly non-linear self-excited systems. Two types of nonlinearities are considered: quadratic and cubic. The solutions are expressed in terms of Jacobian elliptic functions. Higher order ap

The elliptic perturbation method is applied to the study of the periodic solutions of strongly quadratic non-linear oscillators of the form xยจ+ c1 x + c2 x 2 = ef(x, xห™), in which the Jacobian elliptic functions are employed. The generalized Van der Pol equation with f(x, xห™) = m0 + m1 x -m2 x 2 is
