摘要
本文基于考虑横向剪切变形的中厚壳的几何方程、物理方程及中面平衡方程 ,建立关于五个中面位移为五个独立变量的中厚壳的位移型动力方程 .该方程退化为中厚球壳及薄壳的位移型动力方程的正确性说明所推导方程的有效性 .
The paper established the displacemental dynamical equations of the middle-thick shells by transverse shearing deformation,based on the geometric equations,physical equations,and middle surface equilibrium equations,concerning five independent variables,i.e. five middle surface displacements.The equations degenerate to displacemental dynamical equations of the middle-thick spherical shells and the thin shells,which demonstrate the validity of the equations derived.
