对简支边界条件下以正交铺设层板为面板的复合材料夹层板的横向振动进行了求解,在求解中包括了面板的耦合刚度和面板与夹芯间的粘结刚度.计算结果表明,当粘结刚度超过某一值时,可以认为面板与夹芯粘结完好,但当小于这个值时,粘结刚度对自振频率会产生很大的影响,影响程度与面板铺层、夹芯性质、板的长宽比及振动模态有关.作为一个特例,对正交铺设层板中间一个层间界面存在滑移时其振动频率的变化进行了讨论.
The transverse vibration of composite sandwich panels with orthogonal panels is calculated under the condition of simply supported boundary conditions. The solution includes the coupling stiffness of panel and the bonding stiffness between panel and sandwich panel. The results show that when the bonding stiffness exceeds a certain value, it can be considered that the bonding between the panel and the core is intact, but when it is less than this value, the bonding stiffness has a great influence on the natural frequency. The influence degree and panel shop Layer, the nature of the sandwich, the aspect ratio of the plate and the mode of vibration. As a special case, the variation of the vibration frequency of an interlayer interface in the middle of an orthogonal laying plate when it slips is discussed.
