| 摘 要： | 文章基于Love壳体理论,对复合材料层合圆柱壳的振动特性进行了研究。通过比较,文中计算方法所得的结果与文献比较吻合。运用该方法,讨论了简支、固支和自由等边界条件,轴向模态和铺层角度对圆柱壳振动特性的影响。分析表明,在低阶周向模态时,边界条件和轴向模态的影响更大。

| Abstract: | Based on the Love theory, the vibrational characteristics of laminated composite cylindrical shell are studied. The obtained results were evaluated with those in the literature and both are in agreement. With this method, the influences of boundary conditions, axial modes and fiber angles on the vibrational charac-teristics of cylindrical shell are investigated. It is concluded that the influences of boundary conditions and axial modes can be seen to be more significant at small circumferential modes than at large circumferential modes. |
