| 摘 要： | 本文用样条有限元法，分析了反对称角铺设层合板的自由振动问题．在用三次B样条函数构成的样条基对诸独立位移分量进行插值后，根据瑞利-李兹法导出了特征方程，分别计算了反对称角铺设层合板在不同长宽比、不同铺层数、不同铺设角情况下的固有频率，并将有关结果与已有的成果进行了比较．

| Abstract: | The essay analyses free vibration problem of laying bed build-up board of antisymmetry angle with spline finite element method. After inserting value to its independent displacement weight with spline base formed by three-time B-spline function and according to Jili-Lizi Method which infers the characteristic equation, it calculates respectively inherent frequency of antisymmetry laying bed build-up board under the condition of different Length-width ratios, different laying numbers and different laying angle, and it compares the related consequence with the original achievement. |
