摘要
本文首先推导出圆薄板的动力变分方程,用加辽金法得到一个三次非线性振动方程,用多尺度法对非共振硬激发进行了求解,继而对稳定性作了研究。
In this paper, the dynamic variational equation for circular thin plates is derived first. Then a third-order non-linear vibration equation is obtained by using Galerkin's method and the method of multiple scales is used to solve hard excitation problem without resonance, and the stability is studied.
