摘　　要：为大幅度地提高嵌入式共固化复合材料阻尼结构固有频率,优化其刚度,以嵌入式共固化阻尼复合材料薄板为研究对象,利用有限元的方法对比分析了该结构薄板及十字加筋薄板固有振动特性,并得到了筋材薄壁宽度和高度对结构固有频率的影响规律。结果表明:加强筋大大提高了薄板结构的固有频率和刚度,加筋薄板结构的各阶固有频率随着加强筋高度增大而增加,其中一阶固有频率增加幅度最大。增加加强筋宽度可以提高薄板结构的各阶固有频率,随着加强筋宽度的增加,固有频率的增加幅度减小。The purpose of the paper is to greatly improve the natural frequency of the embedded co-cured compos-ite damping structure and optimize its stiffness.The embedded co-curing damping composite structure was taken as the research object.The natural vibration characteristics of the structure and the cruciform stiffener structure were compared and analyzed by the finite element method.The influence of the reinforcement width and height on the natural frequency of the structure was obtained.The results show that the reinforced rib could greatly improve the natural frequency and stiffness of the thin plate structure.The natural frequencies of the reinforced thin plate structure get increased with the increase of the rib height,and the first order natural frequency increases the most.Increase of the width of the ribs could increase the natural frequencies of the thin plates.When the width of the rib is large,the increase of the natural frequency could be reduced.
