Structure bionic design method oriented to integration of biological advantages

Structure bionic optimization design is one kind of important lightweight design method. There are many high-specific-stiffness load-bearing topology structures in nature, whose mechanical properties and load-bearing mechanisms are quite different. These efficient load-bearing structures in nature provide important inspirations for structural bionic design. However, space topology structure of biology corresponds to its specific environment, which is more suitable for the specific load-bearing case. How to realize the complementary integration of biological advantages is an important problem in bionics research, which has not been solved effectively. Based on mapping inversion relationship (RMI) method and the matter-element (ME) theory, the structure bionic design method oriented to the integration of biological advantages is proposed. The proposed method applies the extensibility matter-element in an interdisciplinary way to solve this problem innovatively and effectively. Instead of random or wild mental stimulation, the proposed method formalizes the problem-solution for the integration of biological advantages. An example is used to show the concrete implementation process based on this method, and the results show the effectiveness of this proposed method. The proposed method could be extended to other bionic studies about biological advantages integration in further research.
