“…In the early stage of human civilization, for the purpose of survival, human had to observe the habits of plants, which they lived on, and various natural phenomena around them. Many examples showed that people had taken careful observation and investigation on plant structures and had engaged in plant structural bionic design since ancient times [3]. There were plenty of records, which documented innovative imitation of the morphology and function of plant.…”

“…Bones and teeth can maintain a large compressive force without bending or cracking [ 36 , 37 , 38 ]. Some efforts have been made to apply these advantages to the design of aircraft structures, including aircraft-reinforcing frames and small wings [ 39 , 40 , 41 ]. As a typical microhexapod structure, foraging workers of ants often carry food loads many times their body weight.…”

Owing to their high design freedom and excellent performance, lattice structures have shown outstanding capabilities and great potential in aeronautics and astronautics fields. In this paper, we propose a method to construct lattice structures by parameterizing biological features. An ant-leg configuration is used as the bionic object to generate a bionic lightweight design with a gradient lattice structure. To achieve the above goal, an innovative optimization method combining topology optimization, size optimization, and a bionic lattice structure is proposed in this paper. Taking the support structure of the Fengyun-3 satellite payload as the research object, this optimization method is applied to optimize the design. Further, the reconstructed optimization model and the original model are simulated to evaluate and compare the structural performance. The simulation results show that when combined with bionic lattice structure and structural optimization, the method can achieve the lightweight design goal while ensuring the stiffness and strength of the structure. The results demonstrate that the application of a bionic lattice design in a lightweight design has feasibility and expectable potential.

“…This approach is applied to improve the final structure design and subsystem layout. In terms of the design of the structure for bionic layout, Cen H. [10] designed a bionic wing structure with better performance than its prototype by referring to the constructional characteristics of the leaf vein branches. Ngoc San Ha [11] combined the advantages of bionics and proposed a new bionic sandwich panel based on the microstructure of woodpecker beaks, which provides an idea for the design of a lightweight plate hollow sandwich structure with efficient energy absorption capacity like an aircraft wing provided ideas.…”

The layout of the wing's internal structure not only dramatically influences the wing's strength stiffness but also directly affects the aerodynamic characteristics of the aircraft. Based on the original wing structure, a more flexible spatial design layout to achieve improved overall structural load-bearing performance, and a reasonable structural lightweight design are the research priorities to be considered for the development of future aircraft. Therefore, this paper attempted to design and analyze a lightweight airfoil that meets the performance requirements. Combining the strategy of hierarchical optimization design with the advantages of engineering bionics, the diatom Arachnoidiscus bionic structure, topological optimization, partial least squares regression (PLSR), and multi-objective particle swarm algorithm (PSO) are applied to optimize the placement and size of wing’s internal components. The simulation results show that the weight of the optimized wing structure is reduced by 6% while satisfying the requirements of maximum stress and maximum deformation.
