最小余能原理在弹性圆板动力分析中的应用

The Minimum Excess Principle Used in Dynamic Analysis of Elasticity Round-Plate

本文应用最小余能原理的理论和方法,对弹性圆板进行动力分析,计算了固支边和简支边圆板的固有频率,以及干扰力作用下的动力响应,分别讨论了剪力和周边径向压力对动力参数的影响.

In this paper, the minimum excess principle are used in dynamic analysis of elasticity round-plate. The natural frequencies and the dynamic responses to forced vibrations of elasticity round-plate with fixed edge and simply edge are calculated in detail, and effects of radius pressure and shearing are gave.
