复合材料欧拉一伯努利梁中波特性分析

研究了材料复合系数对复合材料欧拉一伯努利梁中弯扭耦合振动的影响。计算结果表明，低频时，梁中扭转波基本不受材料复合的影响，而弯曲波则在整个频率范围内都要受到材料复合的影响，并且弯曲波的波数是随着复合系数的增大而增大，而扭转波的波数则随着复合系数的增大而减小。

Analysis of Wave Characteristics for Composite Euler-Bernoulli Beam

The effect of coupling between bending and torsional deformations on vibrations oi composite Euler-Bernoulli beams is studied. The results show that the torsional modes are less subjected to the material coupling at low frequencies. The flexural modes are found affected over the entire frequency band. Further more, the wavenumbers of bending wave increase with the ratio of material coupling, while the wavenumbers of torsion decrease with the ratio of material coupling.
