摘要

双稳态柱壳复合结构广泛应用于航空航天可展开系统，其中卷曲是存储和展开的主要方法。为了简化弯折过程的有限元建模，研究弯折过程的强度特性，本文提出了一种基于反建模方法的双稳复合柱-壳结构的简化有限元方法。首先，基于双稳柱-壳结构的聚束区域理论，提出了一种能够得到一端固定边界条件下双稳柱-壳结构几何构型的反建模方法；采用实验方法和有限元方法验证了反建模结果的准确性。然后，基于反建模方法，建立了一种简化有限元方法，实验和仿真结果验证了其与传统有限元方法的精度相当。最后，利用该简化有限元法分析了卷边过程中铺层角和单层厚度对结构强度的影响，为优化设计参数的选择提供了指导。

Simplified FE modeling of bistable column-shell structures and strength analysis during the curling process

Bistable composite column-shell structures are extensively employed in aerospace deployable systems, with curling being the primary method for storage and deployment. To streamline the FE (FE) modeling of the curling process and investigate the strength characteristics, this paper proposed a simplified finite element method (FEM) for bistable composite column-shell structures based on a reverse modeling approach. Firstly, based on the theory of the ploy region of the bistable column-shell structures, a reverse modeling method is proposed, which is capable of obtaining the geometrical configurations of the bistable column-shells under the fixed boundary conditions at one end. The accuracy of the reverse modeling result is verified by using the experimental method and the FEM. Then, based on the reverse modeling approach, a simplified FEM is developed, with both experimental and simulation results confirming its comparable accuracy to the traditional FEM. Finally, using this simplified FEM, the effects of ply angle and single-layer thickness on the structural strength during the curling process are analyzed, and guidelines for selecting optimal design parameters are provided.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
