“…Jihong Zhu demonstrated a shape preserving topology optimization design approach for suppressing the warping deformation of local structural domains [9]. Dimcic Milos applied a relaxed method based on the force density method to a non-uniform Voronoi structure and obtained a foam-like structure through the genetic algorithm [10]. Danil Nagyand and this APworks group combined a bottom-up growth strategy based on slime mould's behavior in nature using a top-down genetic algorithm strategy and by minimizing weight and structural weakness to obtain the final design [11,12].…”

A cellular-based evolutionary topology optimization scheme over a small curvature big contour wing surface is proposed for the design of an ultralight surface structure. Using this method, a ground-structure technique is first applied to obtain homogeneous mesh generation with a predefined weight value over the design domain. Secondly, the stiffener path’s description is guided by a modified map L system topology method that simulates the growth of the bionic branch, and the structural components are obtained by the specified searching method according to weights of the previous mesh vertexes. Thirdly, an optimal curved stiffener layout is achieved using an agent-based algorithm to create individual instances of designs based on a small number of input parameters. These parameters can then be controlled by a genetic algorithm to optimize the final design according to goals like minimizing weight and structural weakness. A comparison is implemented for long-span panel stiffener layout generation between an initial straight case and a bionic optimal case via our method, thereby indicating the significant improvement of the buckling loads by steering the stiffener’s path. Finally, this bionic method is applied to the wing box structure design and achieves remarkable weight loss at last.

“…Some methods of structural bionics rely on redesigning the structure or space using the rules derived from interesting behaviour observed in nature. Nagy et al developed a computational geometry system which searches for novel design using generative design [9]. As slime mould grows, it first spreads out a dense network of connections.…”

“…Simulations comparing shark skin with other geometries revealed that the former substantially reduced wind velocity for all directions. The slime mold, Physarum polycephalum, can connect different sources of food in an efficient manner [8]; this inspired scientists at Airbus to invent a de novo structure for the aircraft cabin partition [9]. The growth process mimicked the network system generated by the slime mold, ultimately obtaining a 50% lighter structure, not compromising on the state-of-art performance.…”

“…With this characteristic, a small amount of -lines‖ is established to connect a set of -key-points‖. We hypothesized that a similar logic may be beneficial for connecting points which in the design domain to resist structural loads [7,8]. The structural members of each design iteration are then sampled from the edges of the graph based on the following algorithm:…”

This article describe a three-step structure layout grow method for a wing structure design. In the first step a ground structure is applied to get the initial structure d method data. In the second step, a bionic method simplified by the slime mould is present to guide the layout grow. In the last step, an optimization method of genetic algorithm is used to guide the tendency to the optimize result. Together, these three strategies create a hybrid approach which ensures high performance.
