摘要: 为了获取复合材料层合板结构的振动特性,以复合材料层合板为研究对象,利用有限元方法分析了该结构的动力学特性,并得到了该结构的主弹性模量比、长宽比和铺层方式对结构固有频率的影响规律。结果表明:结构的前四阶固有频率随着主弹性模量比值和长宽比的增加而增加;随着结构长度和宽度比值的增加,结构的前四阶固有频率的增加幅度增大;一阶固有频率和二阶固有频率随着主弹性模量比值的增加近似呈线性变化;对称层合板结构、反对称层合板结构和非对称层合板结构的前四阶固有频率随着层厚的增加而增加,与其他两种铺层方式相比,反对称层合板结构的前四阶固有频率较大。

Abstract: In order to obtain the vibration characteristics of composite laminate structure, the composite laminate is taken as the research object. The kinetic properties of the structure were analyzed by finite element method. The influence of the main elastic modulus ratio, length to width ratio and layup mode on the natural frequency of the structure is obtained. The results show that the initial fourth natural frequencies of the structure increase with the increase of the main elastic modulus ratio and the length to width ratio. As the length to width ratio of the structure increases, the initial fourth natural frequencies of the structure increase with increasing amplitude. The first-order natural frequency and the second-order natural frequency change approximately linearly with an increase in the ratio of the principal elastic modulus. The initial fourth natural frequencies of the symmetric laminate structure, the antisymmetric laminate structure and the asymmetric laminate structure increase with the increase of the layer thickness, compared with the other two laminate methods, the initial fourth natural frequencies of the antisymmetric laminate structure is larger.

Key words: composite material, finite element, antisymmetric laminated plates, natural frequency
