| Abstract: | An analogue simulation study for the stability investigations of nonlinear parametrically excited structural systems, exhibiting hard and soft spring characteristics is undertaken as a feasible alternative to current asymptotic and other analytic methods. It is shown that this technique locates the position of an unstable limit cycle, identifying the point of change of equilibrium states, which is ordinarily obscured in using the other existing schemes. |
