Description

Technical Field

[0001] This invention belongs to the field of satellite structures and relates to a load support structure that can support multiple devices and has multiple functions. Background Technology

[0002] In the field of remote sensing satellites, the main development direction of new satellites is to improve or expand the performance of high-performance cameras or high-end antennas, and to carry more functional payloads to improve the overall system capabilities of the satellite. With the rapid development of technology, people's functional requirements for satellites are changing rapidly and emerging one after another, making the payloads on the satellite not only powerful, but also more interconnected, and even putting forward a variety of interrelated requirements for the whole satellite. Therefore, in the new remote sensing satellites, there are more performance correlations between various subsystems, and each subsystem needs to provide more new performance services for the whole satellite.

[0003] Different types of satellites have different functional requirements. Some require higher observation accuracy, some require longer monitoring capabilities, and some require long lifespan and less susceptibility to atmospheric influences. One such requirement is the satellite's ability to rapidly change attitude, possess multiple Earth-detection functions, and coordinate various functions across the entire satellite. This necessitates extremely high rigidity and extremely low moment of inertia, enabling rapid attitude adjustments. Furthermore, the satellite needs to carry numerous functional payloads to meet these diverse needs, resulting in a more compact layout and stronger interrelationships among the equipment. Various structures on the satellite serve as the foundation for load-bearing and structural assembly, fulfilling multiple load-bearing and functional requirements. For example, the satellite must meet the light-shielding requirements of its cameras while simultaneously accommodating various payloads around them. This places extremely high demands on the corresponding support structures, requiring a multitude of functionalities. Currently, no design can fully address these requirements, and existing structural designs inevitably present the following problems:

[0004] (1) Camera light-shielding systems prioritize light-shielding functions but have weak load-bearing capacity.

[0005] Traditional camera light-shielding systems only have light-shielding functions and lack load-bearing capacity. They are poorly designed in coordination with the overall satellite layout, occupy significant space on the ground-based satellite surface, and cannot alleviate the difficulties of the overall satellite layout. In particular, modern cameras are becoming increasingly large, with some even exceeding the size of the satellite platform, exhibiting a typical "big head, small body" characteristic. However, the limited load-bearing capacity of the surrounding structure of the camera makes it impossible to install multiple high-precision and heavy devices, resulting in difficulties in utilizing the space around the camera.

[0006] (2) The star top can only be installed on the ground. The large-size installation structure faces the challenges of high bending resistance and extreme lightweight.

[0007] With numerous payload devices and heavy loads, the satellite is only supported at its base, and an extended support structure is designed around the camera without any lateral auxiliary support. The heavier and higher the equipment mounted on the support structure, the greater the bending moment at the root of the entire extended structure. At the same time, the greater the out-of-plane load at the equipment installation location, the greater the load on the extended structure and the more difficult the design. Furthermore, the structure on the ground inevitably faces more stringent weight restrictions, as the weight on the ground often directly causes the center of mass of the entire satellite to rise. Therefore, the ground-based extended structure requires an extremely lightweight design.

[0008] (3) When multiple payload devices are assembled on the satellite, the series operation mode leads to a long overall satellite assembly cycle.

[0009] In traditional satellites, the main payload equipment is assembled on the main structure of the satellite. Due to the limitations of the main structure's operating environment, other equipment cannot be operated simultaneously when the payload equipment is launched. In conventional assembly relationships, a typical satellite has a single main payload equipment. If there are one or two devices, they are launched one after the other. However, current high-performance satellites have many payload devices with different assembly types, making assembly difficult and labor-intensive. The assembly is carried out in a serial mode on the satellite, which is a major pain point for the long final assembly cycle. Summary of the Invention

[0025] The advantages of this invention compared to the prior art are:

[0026] (1) The present invention adopts a structural rigidification and light blocking design scheme, which fully realizes the high load-bearing capacity and light-blocking multi-functional characteristics of the structure;

[0027] The entire satellite's coverage of the ground is often dominated by the camera. However, it is already difficult for the camera to fully mount its own equipment, leaving no space for other equipment. Many devices, such as antennas and detectors, need to perform their functions on the ground. To meet the ground-pointing transmission or detection needs of all devices, it is necessary to develop a three-dimensional space above the ground. Therefore, the load support structure designed around the camera effectively utilizes the external space around the camera, allowing for the full deployment of wall-mounted instruments. It also makes great use of the open space at the top of the satellite that is far from the ground, solving the problem of cramped layout and perfectly realizing the ground-pointing and detection functional requirements of multiple devices.

[0028] (2) The material optimization layout and local stiffening design method of the present invention achieves the highest efficiency of material utilization and at the same time achieves the structural design goal of high stiffness.

[0029] Based on the equipment layout requirements, finite element simulation analysis was used to fully identify the high load and high stress distribution areas on the load support structure. Taking advantage of the designability of composite material structures, reasonable planning was carried out on the ply, and local variable thickness ply design was used in high load-bearing areas to improve local strength. By identifying weak stiffness areas, local stiffness reinforcement design was carried out in the locations with insufficient stiffness. In this way, the material was fully distributed in the necessary locations, maximizing the material utilization efficiency, while solving the problems of insufficient local strength and stiffness. Through local stress diversion, the entire structure was designed as a high bending resistance structure supported only at the root.

[0030] (3) The present invention adopts an independent load support structure to effectively realize modular assembly and improve the assembly efficiency of the whole satellite;

[0031] The camera's light-shielding function is entirely achieved by the load support structure. At the same time, the load support structure and the camera are designed to be isolated from each other and do not interfere with each other. The load support structure's separate modular on-board assembly mode will form two parallel satellite assembly production lines, which will carry out final assembly and even testing work separately. This truly realizes modular separate assembly, greatly improves the overall satellite assembly production efficiency, and lays a solid foundation for coping with the fast and efficient competition in the commercial satellite market.

Through rational layout and optimized material distribution, weak stiffness areas are accurately identified, and localized structural rigidity is strengthened. Materials are rationally distributed according to different local strength requirements, with variable cross-sections and thicknesses to improve material utilization and optimize material weight from a structural perspective. The entire structure uses high-modulus carbon fiber composite material as the main material, better achieving the design goal of lightweight materials. Simultaneously, the use of high-rigidity materials better achieves the overall goal of high bending resistance. To ensure localized stiffness and optimize the overall structural stiffness layout, localized rigid supports are arranged circumferentially inside and outside the main supporting structure, further enhancing localized stiffness with minimal weight resources and adjusting the stiffness distribution of the entire structure.

[0084] This invention effectively decouples the camera and the satellite from the satellite, enabling modular assembly and thus achieving a parallel assembly technology solution with the satellite. During the overall satellite assembly process, the payload support structure can be detached from the top of the satellite and exist independently outside the satellite for equipment installation. Multiple antennas, detectors, various heat sinks, precision measuring mirrors, waveguides, cables, and other equipment are assembled around the payload support structure from bottom to top. Due to the good openness of the outer side of the payload support structure, these assembly processes can be carried out in parallel operations depending on the available manpower. While the equipment is being assembled on the payload support structure, other equipment can also be assembled in parallel in the payload compartment of the entire satellite. After the equipment assembly and fine-tuning on the payload support structure are completed, the modular assembly is finished, and the entire satellite can be lifted back to the upper surface of the payload compartment.

[0085] This invention employs a high-precision interface design with a large-size structure: the upper and lower end faces of the load support structure provide interfaces for various equipment such as multiple antennas, detectors, various heat sinks, precision measuring mirrors, waveguides, and cables, as well as satellite platform connection interfaces. Due to the involvement of multiple loads, most of these interfaces are critical interfaces, requiring the flatness of the load equipment mounting surface to be (0.05~0.15)mm, the flatness of the satellite platform connection interface to be (0.05~0.15)mm, and the positional accuracy of all holes relative to the reference to be Φ(0.15~0.3)mm. The interface accuracy can be met starting from the load-bearing capacity of the load support structure. The overall configuration design starting from the entire satellite mounting surface is designed with the interface characteristics in mind, adopting a fully outward design to achieve open manufacturing. At the same time, in order to eliminate errors in complex processes and meet the interface accuracy requirements, all connection interfaces adopt a glued and screwed connection method with inner and outer hole sleeves. After the product is manufactured, all interfaces are assembled and processed to ensure interface accuracy.
