The invention discloses a multiunit cubesat main load-bearing structure. A main frame is of a rectangular frame structure and provided with rib plates matched with the shape of the long-edge section of the main frame in the direction of the long edges. End covers are arranged at the two ends of the main frame in the direction of the long edges, and the profile of the end covers is matched with the shape enclosed by the main frame. A middle skeleton is arranged at the positions corresponding to the rib plates in the main frame, and the profile of the middle skeleton is matched with the shape enclosed by the rib plates. Four threaded rods are arranged in the main frame in the direction of the long edges, penetrate through the middle skeleton and are fixed to the end covers at the two ends of the main frame. According to the multiunit cubic-star main load-bearing structure, due to the fact that the main frame is of an integrated structure, parallelism among guide rails can be guaranteed, the main load-bearing structure cannot be clamped by a launcher in the launching process, and successful launch is guaranteed; in the cubesat assembling process, internal PCBs can be assembled with the end covers, the middle skeleton, the threaded rods and nuts firstly, and then the assembled whole body is arranged in the main frame in a sleeving mode; the difficulty of the assembling process is greatly lowered, and the internal layout integrity is improved.
