Naked electric power rope system modeling method based on absolute node coordinate method

The invention relates to the technical field of spacecraft flight, in particular to a naked electric power rope system modeling method based on an absolute node coordinate method, which can accurately describe dynamic behaviors of a system. According to the method, firstly, an absolute node coordinate method is used for deducing a kinetic equation of bare electric power rope units, then a natural coordinate method is used for deducing a kinetic equation of a satellite rigid body, finally constraint is introduced, all the bare electric power rope units of the bare electric power rope are assembled, a kinetic equation of the whole system is obtained, and therefore model construction of the system is completed. A dynamic model capable of describing behaviors of the space bare electric power rope system is constructed, and the model can accurately describe in-plane and out-plane movement of the space bare electric power rope system, especially configuration changes of the bare electric power rope. 本发明涉及航天器飞行技术领域，
