摘要
文章用Flügge经典壳体理论讨论了正交各向异性圆柱壳的轴对称和梁式振动,分析了壳体参数和材料参数对壳体频率和振型的影响,还讨论了这两种振动与杆的纵向振动、环的平面内振动以及轴对称轴向运动和轴对称径向运动的关系。
An analysis is presented for axisymmetric and beam-like vibration of an orthotropic cylindrical shell using Flügge classical shell theory.The effects of shell and material parameters on vibration frequen-cies and mode shapes are discussed in this paper.Some comparisons with axisymmetric longitudinal motion,axisymmetric breathing motion,ring motion,etc are obtained.
