摘　　要：针对点阵的功能结构一体化设计问题,提出一种依据梁模型仿真结果增强点阵结构节点的设计方法。以齿轮为载体对辐板填充点阵结构,通过搭建的振动检测平台对点阵结构的功能性能进行验证。实验结果表明,相比质量相同的点阵结构,功能点阵结构的振幅降低20.90%,且承载能力提高30.00%。Aiming at lattice design of the integration of function and structure,a design method for strengthening lattice structure nodes was proposed based on the analysis results of beam model.Taking the gear as the carrier whose web was filled with lattice structure,a vibration detection platform was built to verify the functional performance of the lattice structures.Experimental results show that compared with the lattice structure with the same mass,the amplitude of the functional lattice structure decreases by 20.90%and the loading capacity increases by 30.00%.
