| 摘 要： | 本文用三维弹性动力学理论研究圆柱体在两端简支约束下的轴对称自由振动问题。给出位移振型和应力振型的解析表达式，求得固有频率的精确解。研究结果表明：在圆柱体的径向还存在着不同的半波数的位移振型，这种性质在初等理论中是无法反映的

| Abstract: | In this paper,the axisymmetric free vibration of a simper supported cylinde is studed by the three-dimessional elastodynamics。 The analytical expressions for the displacement and stress models and the exact values of the natural frequencies are obtained。 It is found that there are model shapes of displacements with different wave numbers along the diameter of cylinder. That is impossiblg shown from the essential theory. |
