Design of lightweight split support structure for large space off-axis three mirror camera
According to the design requirements of lightweight and high-stiffness large-scale space camera frame support structures with a 1-m resolution and 200-km width, a lightweight split support structure is designed. In this study, a high-volume SiCp/Al composite material with good performance is selected based on the development requirements of a large space off-axis three-mirror camera, including the specific stiffness, thermal stability, and processing technology. Then, with the structure mass fraction as the constraint condition, a topology optimization mathematical model is established with the fundamental frequency as the objective function, and the optimal force transfer path of each split structure with clear topological results is obtained. The size of each part of the main support structure is optimized, and the optimal configuration and design size of each split structure are obtained. After the design, the total weight of the split support structure was 227.8 kg, and the lightweight rate reached 93.9%, which meets the requirements of high lightweight and stiffness. The results of finite-element analysis and mechanical prototype test show that the split support structure meets the stiffness requirements of the whole remote sensing camera with the fundamental frequency greater than 50 Hz, and the deformation of the mirror is within the tolerance range under the working condition of 5 °C, which fully satisfies the requirements of the satellite platform for optical loads. The mechanical prototype mirror assembly offset angle is less than 22° before and after the vibration test, showing its good stability, which proves the rationality and feasibility of the topology optimization and size optimization methods. The design of the proposed split support structure has a high engineering practice value for the support design of large space off-axis cameras.
