The invention provides a digital design method and equipment for a spaceflight fastening connection system and a medium. The method comprises the following steps: preferably pushing a fastener based on logical judgment; performing forward design simulation calculation on the fastening connection system, wherein the fastening connection system comprises a pushed fastener; and based on the simulation calculation result, the fastening connection system is automatically assembled. According to the method provided by the invention, after the fasteners are preferably pushed based on logic judgment, the fastening connection system comprising the pushed fasteners is simulated and assembled, so that accurate selection, reliable design and standard installation of the fasteners are realized, the digital optimization design capability of the fastening connection system is improved, and the reliability of the fastening connection system is improved. Key technologies such as optimal pushing of fasteners, simulation calcul
