CHAOTIC FIELD’S ANALYSIS OF SIMPLY AND CLAMP SUPPORTED MAGNETO-ELASTIC THIN CIRCULAR PLATE

摘要：

Based on the expression of electromagnetic forces and nonlinear electro-magneto-elastic equations of the thin circular plate, the vibration equations of a thin circular plate with simply supported and clamped edges under the action of uniform transverse magnetic field, together with a circulating electric current, and conventional uniform distributive force, are obtained first. In order to trace vibration behaviour the largest Lyapunov exponent is calculated. By changing the magnetic field and electric current the chaotic field under the diffent boundry conditions are obiained. The chaotic field explicit the transmit thin circular plate under the certain condition have some characters. The periodic field and the chaotic field is continue and the bifurcation field is noncontinue. The dynamic behavior of the thin circular elastic plate could be controlled.
