###### Abstract
This enables more flexible and diverse designs for aerospace components, allowing for efficient integration of functions such as load-bearing, heat dissipation, and wave absorption within a single optimized part. [PERSON] et al. [19] presented a minimum weight formulation with stress constraints that allow for the avoidance of most of the drawbacks associated with maximum stiffness approaches. [PERSON] et al. [20] developed a methodology that combines the Sequential Optimization and Reliability Assessment (SORA) with external optimization software to perform Reliability-Based Topology Optimization (RBTO) of aeronautical structures. Based on the finite element method (FEM)and additive manufacturing (AM) technologies, [PERSON] et al. [21] used the topological optimization methodology to redesign the connector support of the VEGA space launcher, a typical lever component from civil aircraft and housing part from fan cowl structures. [PERSON] [22] described the background of the method and showed some applications, ranging from the design of materials with 'exotic' properties over microscopic robots to the design of large-scale satellite structures. Many scholars have carried out topology optimization with the goal of maximizing structural stiffness. [PERSON] and [PERSON] [23] reviewed various formulas for structural and mechanical system optimization, with particular emphasis on the traditional formula, the Simultaneous Analysis and Design (SAND) formula, and the displacement-based two-stage approach, which provided a theoretical basis and framework for subsequent research. [PERSON] et al. [24] further explored the optimal uniform strength design of frame and lattice structures, and optimized the structure layout to ensure uniform strength in all parts, to improve the overall performance without increasing weight. [PERSON] et al. [25] combined shape and topology optimization techniques to minimize the maximum von Mises stress while keeping the structure lightweight, providing a new perspective for the optimal design of complex structures. [PERSON] and [PERSON] [26] carried out research on the optimal structure of planar micro lattice materials with a minimum weight under the constraints of synchronous axial stiffness and shear stiffness. [PERSON] et al. [27] pointed out that additive manufacturing is an advanced manufacturing technique for building as-designed structures via layer-by-layer joining material, providing an alternative pattern for complex components and reviewed the main content and applications of the research on the integration of topology optimization and additive manufacturing in recent years, including multi-scale or hierarchical structural optimization design and topology optimization considering additive manufacturing constraints. The mechanical performance of the 3D-printed beam meets the standards of forged parts, demonstrating the significant advantages of additive manufacturing in lightweight. [28]. State-of-the-art research for structural topology optimization and their applications in aerospace structures in industries can be found in [PERSON] et al. [27]; [PERSON] and [PERSON] [29]; [PERSON], and [PERSON] [30]; and [PERSON] et al. [31]. The structure of satellite launch devices is complex, with the camera support frame positioned at a critical junction between key components. It also experiences impacts and vibrations during satellite transport and launch. Operating in such harsh environments poses significant challenges to the mechanical performance of the camera support structure. It must provide sufficient strength and stiffness while minimizing weight to reduce the satellite's burden. This study performs lightweight topological optimization on the camera support structure. The organization of this paper is as follows: Section 1 provides an overview of optimization theory and structural mathematical models. Section 2 presents the initial mechanical analysis of the structure. Section 3 discusses the results of the topological optimization design.
