本文研究了复合材料夹层板壳的一种等效分析方法，首先由壳体理论导出了夹层板壳的内力和位移表达式，通过与各向异性单层板壳理论的比较，提出了二者等效的条件，从而把夹层板壳问题简化为一个等效各向异性单层板壳问题，这用有限元法很容易求解，并对一个工程实例进行了计算，证实了该方法的有效性。 In this paper, an equivalent analysis method of composite sandwich plates is studied. Firstly, the internal forces and displacement expressions of sandwich plates are deduced from shell theory. By comparing with anisotropic single layer shell theory, Equivalent conditions reduce the sandwich shell problem to an equivalent anisotropic one-shell shell problem, which is easily solved by the finite element method. An engineering example is calculated to confirm the effectiveness of the method .
