| 摘 要： | 笔者以具有代表性的各向异性复合材料反对称角铺设层合板为例,对其在简谐激振力作用下的非线性弯曲强迫振动问题做了包括算例在内的全解析过程分析.得到各向异性反对称角铺设层合板在各种级别荷载作用下的幅-频关系,以及层合板结构铺设层数的变化对非线性弯曲强迫振动幅-频关系的影响,所求得的解析形式的结果保证了结果的可靠性以及由此所推得的结论的代表性.本文工作无疑是复合材料层合板非线性动力问题的一个有意义的尝试,它们对于以后探讨各向异性层合板其它方面的非线性动力问题具有一定的意义.

| Abstract: | By taking unsymmetrically angleply laminated plates of anisotropic composites as an example to make an analysis of tha complete solution analysis process (including calculating examples) of non-linear flexural forced vibration of plates under the harmonic force,the writers obtain amplitude-frequency relationship of anisotropic unsymmetrically angle-ply laminated plates under the load of different-magnitude,and the effect of the change in plying layers of laminated plats upon the amplitude-frepuency relationship of non-linear flexural forced vibration.The solution analysis result thus obtained is reliable and the conclusion drawn from the result is representative.What has been done so far is undoubtedly a meaningful attempt in the matter of non-linear dynamics of anisotropic laminated plates and will be a great help in the further research of some other note-linear dynamics of anisotropic laminated plates. |
