针对疏排圆形胞元蜂窝面内结构，建立了圆形胞元蜂窝结构一种新的等效力学理论模型。通过结构力学等相关理论知识，提出了一种求解结构面内力学参数的新思路，得出该结构面内等效力学参数的理论近似解；并通过Ansys有限元软件对该结构进行建模，并施加适当载荷，计算结构在载荷作用下的形变，进而得到相应的数值模拟仿真结果。理论数值结果与有限元仿真结果表明，该近似等效力学模型具有一定的精度和合理性，可为疏排圆形蜂窝夹芯结构的面内力学特性分析研究提供新的理论分析方法。 A new equivalent mechanical model of circular cellular structure was established according to the structure of the thin circular cell. Through the structural mechanics and other related theories, this paper puts forward a new method for solving structural plane mechanical parameters; obtains the equivalent mechanical parameters of the structural plane theory of the approximate solution; through the finite element software Ansys to model the structure, applies the appropriate load; calculates deformation of structure under load, and then gets the corresponding numerical simulation results. The numerical results with the finite element simulation results show that the equivalent mechanical model has the certain accuracy and rationality; we can analyze and provide a new theoretical analysis method for the drainage of mechanical properties of circular honeycomb sandwich structure plane.
