本文对复合材料夹层板的动态问题提出了一种新的位移修正模式，该位移模式包括了面板的横向剪切变形及夹芯的剪切变形，以此位移模式进行了有限元分析，给出了形成阻尼矩阵的方法。文中还分析了夹层板的阻尼比ψ与夹芯厚度ｈｃ，夹芯材料的阻尼损耗因子β以及夹芯剪切模量Ｇ之间的关系；算例与实验结果的对比表明：本文提出的计算方法可以给出满意的数值结果。
In this paper, a new displacement correction mode is proposed for the dynamic problem of composite sandwich panels. The displacement model includes the transverse shear deformation of the panel and the shear deformation of the sandwich. The finite element analysis The method of forming a damping matrix. The relationship between the damping ratio ψ of the sandwich plate and the thickness of the core hc, the damping loss factor β of the core material and the shear modulus G of the sandwich was also analyzed. The comparison between the calculated results and the experimental results shows that the proposed calculation The method can give satisfactory numerical results.
