| 摘 要： | 根据均布载荷作用下夹层圆板非线性振动的基本方程,得出具有初挠度夹层圆板的非线性振动方程,利用李雅普诺夫稳定性定理分析奇点的稳定性,并对两种情况下奇点的稳定性进行比较,最后通过绘制相轨迹图线进一步验证奇点的性质。

| Abstract: | In this paper,on the base of the quiet balance question of circular sandwithplate with uniform load,we obtain the nonlinear vibration of circular sandwithplate with initial deflectionand,use the Lyapunov's stability theorem,analyze stability of singularity,and compare the stability of two instance,lastly the characteristic singularity is more validated by use of the phasic track curve. |
