【摘要】 本文继[1]和[2],进一步研究了各向异性复合材料反对称正交铺设层合板在简谐激振力作用下的非线性弯曲强迫振动问题,做了包括算例的全解析过程分析,得到了层合板在各种条件下的幅—频关系,并详细讨论了反对称正交铺设层合板的几何尺寸对非线性弯曲强迫振动幅—频关系的影响。更多还原

【Abstract】 This paper is a follow—up of Ref.[1]and Ref.[2].In the paper,the author discusses the geometric nonlinear flexural forced vibration of anisotropic composite un- syummetric cross—ply laminated plates under the harmonic force,studies the complete solution analysis process including computing examples,obtains the illustrative ampli- tude—frequency relationships of the rectangular laminated plates with different aspect rations and especially analyzes the effect of the geometric sizes of anisotropic composite unsymmetric cross—ply laminated plates on their amplitude—frequency relationships of nonlinear flexural forced vibration.更多还原
