摘要
采用考虑了横向剪切变形和转动惯量的厚板条的各阶振型作为有限条的条向连续函数,而质量矩阵计入转动惯量.用此有限厚条法分析多层复合板的横向振动,推导出刚度矩阵.并通过算例与有限元解进行比较,说明本文方法具有收敛性好、自由度少的特点,从而使计算更加简便.
The vibration of multisandwich composite plates is analyzed by use of finite thick strip method and the stiffness is derived,as compared with conventional finite strip method,and the advantage of the method is that the vibration modes of thick stripis used as continuous functions and mass matrix is consided in moment of inertia,in which the shear deformation effect and rotatory inertia is considered.
