摘　　要：以双曲球壳复合材料夹芯结构为研究对象,利用有限元Block Lanczos分析法对双曲球壳结构的自由振动进行了研究,进而得到了基层厚度、芯层厚度以及环境温度等参数对固有频率的影响规律,为实际工程中复合材料夹芯结构的振动分析提供了一种有效的分析及建模方法。Taking the composite sandwich hyperbolic spherical shells as the research object, the free vibration of the hyperbolic spherical shell structure are analyzed by using the Block Lanczos analysis method, and the influence rules of base layer thickness, core layer thickness and environment temperature on the natural frequency are obtained, which provides an effective analysis and modeling method for the vibration analysis of the composite sandwich structure in actual project.
