Small celestial body detector multi-node flexible connection method

Abstract

The invention discloses a small celestial body detector multi-node flexible connection method, and belongs to the field of aerospace. The implementation method comprises the following steps: acquiringscene information including the gravitational acceleration of an asteroid, the number of nodes and the initial speed and position of the nodes; making a flexible mechanism be equivalent to a spring with damping, considering weak gravitation continuous collision of nodes in the attachment process, establishing an instant collision model based on a recovery coefficient method, obtaining a node speed value after collision, generating a multi-node motion track through a detector multi-node coupling motion model, obtaining stable attachment time and node attachment errors of the multi-node network, deleting the non-connected network by traversing all nodes of the network, and calculating residual network related indexes, and establishing an evaluation function of the multi-node connection network according to the average stable attachment time and the average maximum attachment error of the multi-node network under different network indexes, and establishing a corresponding multi-node flexible connection mode through a minimum evaluation function value to realize multi-node flexible connection of the small celestial body detector.

Description

technical field [0001] The invention relates to a multi-node flexible connection method for a small astronomical body detector, which belongs to the technical field of aerospace. Background technique [0002] With the continuous improvement of human deep space exploration technology, the international research on small celestial bodies has gradually increased, and the detection of small celestial bodies has gradually become a hot spot in the space exploration of the solar system. Since the beginning of the 21st century, with the rapid development of aerospace technology, various aerospace powers have carried out a series of deep space exploration activities, and people have gradually begun to pay attention to the large number of small celestial bodies full of unknowns. In the past 30 years, NASA, Japan and the European Space Agency have all proposed and implemented small celestial body detection programs. Among them, the United States has carried out the largest number of sm...

Problems solved by technology

For multi-node networks, there are a large number of configurations. Without considering the mutual influence of flexible connections, it is a complex task to find a connection method that can dissipate energy in a short time and make the error between the actual location of the node and the target location smaller.
