| 摘 要： | 由于复合材料层合板的横向剪切模量较低,因此基于克希霍夫理论而计算的层合板特征值及其灵敏度与实际情况相差较大。本文采用层合板的一阶剪切变形理论,将纤维铺设角、材料参数和从层合板的中面到第K层板上表面的距离ZK视为设计变量,研究了对称层合板特征值的灵敏度计算问题。

| Abstract: | As laminated composite plates have relatively low transverse shear modulus, Kirchhoff theory has been proved to be inadequate for calculating the eigenvalues and their sensitivity in laminated plates. A first order shear deformation theory is used for symmetrically laminated plates in the paper. The orientation angle of fibres, the material parameter and the vertical distance from the middle plane of the laminated plates to the upper surface of each ply are treated as design variables, and the sensitivity of eigenvalues for the symmetrically laminated plates is studied. |

| Keywords: | first order shear deformation theory symmetrically laminated plates natural vibration sensitivity |
