摘要
首先推导出圆薄板的动力变分方程 ,用Galerkin法得到一个三次非线性振动方程 。
The dynamic variational equation of thin circular plate is derived first. Then, using Galerkin method a third order nonlinear vibration equation is obtained. Finally, using Flouquet exponential and Melnikov method, the bifurcation problem with the circular plate and its potential chaos vibration are studied, respectively.
