# Optimization Design of Space Camera Enclosure Based on Bionics
###### Abstract  
To optimize the design of the space camera enclosure, this paper employs biomincity methods. The study compares the structural characteristics of the tendons and veins of the _Victoria lindl_, analyzes the similarities between the reinforced tendons and the _Victoria lindl_ structure, and explores the feasibility of biomincity design. An evaluation factor set and judgment matrix are established for both, and a similarity evaluation is conducted. Utilizing the Solidworks-Ansys interface, parametric modeling is performed, completing the biomimetic initial structural design of the space camera enclosure. Incorporating response surface optimization design principles, the study examines the relationship between the dimensions of stiffener and substrates, the maximum deformation of the enclosure, and the first-order natural frequency. Genetic algorithms are employed for optimization, leading to a secondary optimization design for the space camera enclosure. Through Ansys simulation analysis, a comparison is made between the first-order natural frequency, maximum deformation, and enclosure weight of the space camera enclosure before and after optimization. The results indicate that the biomincity-inspired space camera enclosure structure, modeled after the tendons of _Victoria lindl_, can reduce weight by 36.9% compared to traditional designs, while maintaining high stiffness and fundamental frequency. This offers a novel approach for research in this field. space camera enclosure; biomimetic structure; stiffener; _[PERSON] lindl_'s tendons and veins; finite element analysis; response surface optimization 2020 IEEE/RSJ International Conference on Robotics and Automation (ICRA), Vol., pp. 2020-2020, 20 ribs for thin-walled plate structures has garnered increasing attention from scholars [3]. [PERSON] et al. employed the variable thickness method in topology optimization to optimize the thickness of the original structural substrate, identifying areas that required strengthening. Then, within process constraints, they optimized the height, width, and spacing of the reinforcement ribs [4]. [PERSON] et al. added numerous discrete shell elements to the original thin-walled structure to simulate the reinforcement bars, subsequently performing topology optimization on these reinforcement bar structures to achieve a clearer layout of reinforcement positions [5]. Thirdly, bionics has seen rapid development this year. Countless species of organisms, which rely on Earth for survival, have evolved over the years to form many unique structures capable of adapting to various environments [6]. This provides researchers with numerous new ideas for their design work [7]. In the field of mechanics, [PERSON] et al. proposed a method for manufacturing shell structures by optimizing shell thickness parameters. This approach enhances the strength of the shell structure without increasing the overall weight of the structure [8]. [PERSON] et al. proposed a design method for reinforced thin shell structures, drawing inspiration from the mechanism of plant root morphology formation [9]. [PERSON] and others utilized bionics principles to develop a new type of grid structure system. This system not only improves structural stability but also achieves lightweight design and reduces production costs [10]. In addition, the honeycomb sandwich structure, as a classic application in the aerospace field, is a brilliant crystallization of bionic wisdom. [PERSON] and others developed an identification/validation strategy based on experimental tests, which is remarkable for its accuracy and wide applicability. This strategy deeply analyzed the mechanical properties of sandwich panels with Nomex honeycomb cores under compression conditions, providing a solid scientific basis for the design of aircraft fuselages and cabin doors, and greatly enhancing the strength and safety of the structure [11]. [PERSON] and others drew inspiration from leaves and conducted in-depth research on the unfolding mechanism of leaves.
