| 摘 要： | 本文基于小应变、小位移的假设,用有限元法分析了单层波纹管在轴对称振动时的自振频率。文中采用三节点曲边壳元,位移、转角作为独立变量在总体坐标系下进行插值。

| Abstract: | In this paper the symmetrical free vibration of single—ply bellows are studied by using the finite element method on assumption that strains and displacements are infinite small. Elements with three nodes are used. Displacements and rotations of the elements are interpolated independently in the general coordinate. Some typical examples are calculated. The comparision of computational results with EJMA shows that the program has good accuracy and is available. |
