四边简支载流薄板的稳定性分析

The Stability Analysis of Rectangular Thin Plate Simply Supported at Each Edge

在已知横向磁场与机械载荷共同作用下薄板的磁弹性动力稳定方程的基础上,利用Galerkin法将方程整理为马丢方程,讨论了当薄板只受到动载荷作用时系统的分岔行为,并绘出了分岔图.

Based on the magnetic dynamic stability equation of thin plate in the transverse magnetic field and mechanical load,the Mathieu equation is obtained by Galerkinb method. And the bifurcation behavior is discussed when the plate is under the action of dynamic load,and the bifurcation diagram is drawn.
