本文用有限元法分析了如图1所示的纤维复合材料结构的旋转壳体。计算后给出各节点的位移、内力、封头处各节点内外两个单层的应力值和强度破坏裕度、筒壳处两个层组各自内外单层处各节点的应力值和强度破坏裕度。1.单元的选取 单元选取双曲拟协调单元,每个节点有三个未知数,单 This article uses the finite element method to analyze the rotating shell of the fiber composite material structure shown in FIG. After calculation, the stress values ​​and strength damage margins of the two single layers inside and outside the nodes at the displacements, internal forces, heads at the end of the head, and the stress values ​​and strength failures of the nodes at the inner and outer monolayers of the two layer groups at the shell are given. Margin. 1. Selection of cells The unit selects hyperbolic pseudo-coordinated cells, each node has three unknowns, single
