Fundamental Frequency of Transverse Vibration of Honeycomb Cylindrical Shells With Cutouts and Simply- Supported at Both Ends

建立了两端简支带开孔的蜂窝夹层结构圆柱壳和截锥壳横向振动基频的分析计算近似公式。经验证,分析与实验是相符的。

An approximate analytical formula is proposed for calculating the fundamental frequency of the transverse vibration of honeycomb cylindrical shells with cutouts and simply - supported at both ends in this paper . The formula can also be used for calculating the fundamental frequency of transverse vibration of honeycomb truncated conical shells with cutouts and simply - supported at both ends using the concept of equivalent cylinder . The experimental result supports the theoretical analysis .
