摘要
研究了用于传感器弹性元件波纹扁球壳的非线性动态屈曲问题。建立了波纹扁球壳的非线性振动微分方程,根据突变理论建立了该壳体动态屈曲的突变模型,得到了动态屈曲的临界方程。
In this paper, the problem of nonlinear dynamic buckling of corrugated shallow spherical shell used sensor component is studied. The differential equations of nonlinear vibration of the shell are obtained. The cusp catastrophe model of nonlinear dynamic buckling is developed using catastrophe theory. The happening conditions of dynamic buckling is discussed. The critical equation of dynamic buckling of the shell is obtained.
