| 摘 要： | 利用复合材料叠层结构剖面翘曲修正理论和瑞利原理，导出了叠层梁的固有振动方程，然后利用升阶谱有限元法作数值计算，给出了叠层梁的动态特性及相应的动应力分布。与一阶剪切理论相比，指出一阶剪切理论在高频计算时有较大的误差

| Abstract: | Natural vibration equations are derived by use of the sectional warping corrective theory for composite laminated beams and Rayleigh method at first, and then hierarchial finite element method is adopted during numerical analysis. The obtained results for both of dynamic characteristics and dynamic stress distribution are compared with the solution of the first order shear deformation theory. It is shown that the first order shear deformation theory is more erroneous in high frequency calculation. |
