| 内容記述 | Advancements in CubeSat technologies are transforming both space research and commercial satellite applications. These innovations have greatly improved CubeSat missions' capabilities, with modern CubeSats now featuring advanced instrumentation, enhanced communication systems, and improved propulsion technologies. Consequently, CubeSats can undertake more complex missions that were once the domain of larger satellites, including Earth observation, astronomical research, and interplanetary missions. A notable trend is the increasing interest in deploying constellations of CubeSats for comprehensive coverage and continuous monitoring. The commercial viability of CubeSats in constellation missions is also rising as their capabilities expand. Private space firms are becoming key players in this field, attracted by the relatively low cost of deployment, the potential for rapid technology updates, and scalable constellations. As demand for CubeSat constellations grows, so does the need for their mass production. Efficient and standardized design and development processes are crucial for producing CubeSats in large quantities at a reduced cost. The efficiency of these processes is vital to meeting time and budget constraints. Any inefficiency in the product development process can amplify the effects of these constraints, especially when producing items in large quantities. A primary source of inefficiency is the complexity of satellite configuration during design, testing, and upgrading, which impacts project time and cost. Several factors contribute to the complexity of CubeSat assembly and deployment. The traditional CubeSat mechanical interface uses a stacking arrangement, where systems are layered, leading to interconnected internal subsystems. This increases interdependency during assembly, requires numerous structural parts, and raises both assembly time and production costs. Unlike the standardized external interface with the launch vehicle, CubeSat internal interfaces lack standardization. This lack of standardization presents several challenges. Commercially available CubeSat subsystems often have unique interface requirements, making them incompatible with other subsystems. Customizing these interfaces to meet specific mission requirements significantly extends development time and costs due to the need for design validation and testing. Testing and upgrading CubeSats with non-standard interfaces is also more complex and time-consuming, as each satellite requires unique configurations, complicated testing and repairs. Incompatibility issues between subsystem interfaces can sometimes force designers to compromise on mission objectives. Custom designs generally exhibit lower reliability, with a higher likelihood of errors and failures during integration. Mechanical and electrical mismatches can cause critical mission issues, further complicating the design and integration process. Non-standardized interfaces also limit flexibility, making it difficult to swap out or upgrade subsystems easily. This lack of flexibility hinders the ability to adapt CubeSats for different missions and quickly incorporate new technologies. These challenges highlight the importance of developing standardized and versatile interfaces to facilitate easier integration and enhance mission success. To address these inefficiencies, it is crucial to evaluate design complexity and efficiency for higher performance in mass production. Design performance evaluation tools used in industrial products, such as Design for Manufacturing and Assembly (DFMA) and complexity analysis, can provide valuable insights during the initial development phase. Implementing these tools in satellite systems can mitigate design and manufacturing-related issues, enhance assembly performance, and reduce costs. Design modularity plays a significant role in providing flexibility among subsystems for easy assembly, testing, and upgrades. This study aims to investigate the efficiency of various CubeSat platforms' mechanical interfaces by applying industrial design evaluation tools and developing a modularized, simple, and flexible platform. The goal is to standardize the developed platform by defining an interface that maximizes the efficiency of existing interfaces. This standard interface aims to address compatibility issues among different vendors, enhance design flexibility, and ultimately lead to more efficient and successful missions, particularly in cost- and time-sensitive mass production CubeSat missions. |
