Abstract

The invention discloses a truss type satellite structure suitable for a point type satellite-rocket separation mode, and the structure comprises a composite truss and a honeycomb sandwich structure plate, and is provided with a platform cabin and a load cabin; the composite truss comprises platform cabin truss vertical rods, load cabin truss vertical rods, truss transverse rods, lifting connectors, satellite-rocket separation connectors and inter-cabin butt joints. The load cabin truss vertical rods are in one-to-one correspondence with the platform cabin truss vertical rods; the bottom ends of the platform cabin truss vertical rods are fixedly connected with satellite-rocket separation joints, and the top ends of the platform cabin truss vertical rods are fixedly connected with the bottom ends of the load cabin truss vertical rods through inter-cabin butt joints; the top end of the load cabin truss vertical rod is fixedly connected with a lifting connector. The satellite structure can meet the requirements of a satellite on strength, rigidity, precision and various interfaces, is easy to process and assemble, and can meet the requirements of batch production and modular subdivision operation of products.

Description

technical field [0001] The invention relates to the technical field of satellite structure design, in particular to a truss-type satellite structure applicable to a point-type satellite-rocket separation method. Background technique [0002] At present, the structure of domestic non-returnable satellites mostly adopts a central load-bearing tube plus a structural plate (plate tube) configuration or a structural plate (plate frame) configuration, and the carrying interface is mostly used to connect and separate the belt. With the requirement of satellite network for multi-satellite launch satellite structure, the previous plate-tube and plate-frame satellite structures have been difficult to meet the requirements of point-type explosion bolts and star-arrow connection separation for multi-satellite launch. Contents of the invention [0003] In view of this, the present invention provides a truss-type satellite structure suitable for the point-type satellite-rocket separatio...
