Abstract
The stability of the harmonic solution of the forced Duffing equation governing the relative motion of a load on an inclined plate rotating at a constant angular speed about an arbitrary axis is studied. The load is supported by two identical simple shear springs made of a quadratic rubber-like material. It is found that the stability of motion about the center points is governed by the solutions of Hill's equation with three parameter. For certain values of the design parameters, Hill's equation reduces to the Mathieu equation and stability of the motion is studied following the standard procedure. In the general case, an intermediate bifurcation of the response amplitude occurs for motions about the negative center points. It is shown that the position of the center of mass of the load with respect to the plate center in the undisturbed state affects the nature of the response to a great extent. Without extensive analysis, the stability of motion in the general case is predicted for a specific range of the values of the angular speed of the plate.
