摘要
研究了三维石墨烯泡沫增强微型武器壳体的动态响应。首先基于修正的偶应力理论(MCST)和Love薄壳理论推导出系统的控制方程;其次采用Galerkin法和模态叠加法对GFRNC(三维石墨烯泡沫增强聚合物)微壳进行了固有频率和动态响应分析;最后详细讨论了三维石墨烯泡沫重量分数、分布类型、尺度参数、泡沫系数和几何形状对微壳动态响应的影响。
This paper investigates the dynamic response of three-dimensional graphene foam(GF) reinforced micro weapon shells. Firstly, the governing equation of the system is deduced based on modified couple stress theory(MCST) and love thin shell theory. Then, the Galerkin’s technique and the modal superposition method are employed to obtain natural frequencies and dynamic response of graphene foam reinforced nanocomposite(GFRNC) microshells. Finally, the impacts of the weight fraction, the distribution type, scale parameters, the foam coefficient and the geometry of the three-dimensional GF on the dynamic response of the microshells are discussed in detail.
