Abstract

The present invention provides a main frame of a small high-orbit satellite public platform, the main frame of the small high-orbit satellite public platform includes a shell, a middle partition, a platform cabin main load-bearing truss group and a load cabin load-bearing truss, wherein: The shell forms an accommodating space, and the intermediate partition divides the accommodating space into a platform compartment and a load compartment; the main load-bearing truss group of the platform compartment exerts a supporting force on the part of the shell forming the platform compartment and the intermediate partition ; The loading truss of the load compartment exerts a supporting force on the part of the shell and the intermediate partition forming the load compartment. The main load-bearing structure of the main frame of the small high-orbit satellite public platform is composed of the main load-bearing truss group of the platform cabin, the load cabin load-bearing truss, the embedded frame of the bottom plate, and the embedded frame of the partition.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a main structure of a common platform for small high-orbit satellites. Background technique [0002] The main structure of satellite platform is one of the core technologies of satellite products. The main structure with high bearing ratio, high specific stiffness, high specific strength, low cost and easy mass production and development is an effective guarantee for the competitiveness of satellite products. The truss-type satellite main load-bearing structure has the advantages of high net space value, simple and efficient force transmission characteristics, less restrictions on the carrying envelope, good stiffness and integrity, and is increasingly used as the main load-bearing structure in satellite public utilities. Among the platforms, such as the BSS-601 / BSS-702 / BSS-702SP series platforms of Boeing Company of the United States. And for the high-orbit satellite public ...
