根据柱形壳的一般理论,可以建立承受轴对称载荷的圆柱形壳变形方程:(d~4y/dx~4)+4β~4y=q/D式中:β~4=K/4D=Eδ/4r~2D D=Eδ~3/12(1-μ~2)——壳的柱状刚度; y——壳的径向位移分量; δ——壳的厚度;
According to the general theory of cylindrical shell, the cylindrical shell deformation equation can be established under axial symmetric load: (d ~ 4y / dx ~ 4) + 4β ~ 4y = q / D where β ~ 4 = K / 4D = Eδ / 4r ~ 2D D = Eδ ~ 3/12 (1-μ ~ 2) - the cylindrical stiffness of the shell; y - the radial displacement of the shell; δ - the thickness of the shell;
