| 摘 要： | 本文对厚圆柱壳的非轴对称振动进行了分析，其中除包含通常的薄膜和弯曲效应外，还反映了转动惯性，横向剪切变形和横向挤压的影响，数值结果表明：对于厚圆柱壳来说存在着频率密集区，频率位置发生移动，横向挤压的影响必须要考虑。

| Abstract: | In this paper, the nonaxially symmetric vibration of thick cylindrical shells is analysed. The present work takes consideration, in addition to the usual membrane and bending effects in the vibration, also the influence of rotatory inertia, the transverse shear deformation and the transverse normal extrusion. The numerical results demonstrate that for thick cylindrical shells there exists a dense region of frequencies and the position of frequencies on the frequency table may be shifted, that the influence of the transverse normal extrusion must be considered. |
