Abstract

The embodiment of the invention discloses an analysis method for the existence of chaotic motion in a space tether system, relates to the field of spacecraft flight technology, can effectively predict the occurrence of chaotic motion, and avoids the impact of irregular chaotic motion on the space tether system. The invention includes: collecting the state parameters of the in-orbit spacecraft and the terminal load, and obtaining the space tether system according to the state parameters; obtaining the parameter plane according to the orbit inclination and orbit height of the space tether system; using the The parameter plane is used to detect the existence of chaotic motion in the space tether system through a judgment model. The invention is applicable to the flight attitude monitoring of the space tether system.

Description

technical field

[0001] The invention relates to the technical field of spacecraft flight, in particular to an analysis method for the existence of chaotic motion of a space tether system. Background technique

[0002] Due to the strong nonlinear structure of the space tether system itself, there must be a large number of nonlinear phenomena during the orbital flight, such as internal resonance, bifurcation, almost periodic motion, chaos, etc. In particular, the phenomenon of chaos has attracted the close attention of the majority of scientific researchers.

[0003] The current research mainly includes: for the transient chaotic motion of the high-dimensional undisturbed tethered satellite system, analyze the transient chaotic phenomenon that may occur when the initial state of the system is near the unstable equilibrium point; for the space tethered system chaotic motion and orbit The research on the relationship between eccentricity and analysis shows that when the orbital...
