A Method of Constructing the Mathematical Model of a Discretely Developing Large Space Structure

A new method was proposed to describe the on-orbit mounting of large space constructions that is accompanied by discrete changes in their mechanical structure and dynamic characteristics as controlled plants. Consideration was given to designing the initial (Lagrangian) model for each interval of invariable structure of the discretely developing construction. A graph-based computational procedure of reducing the initial model to the modal-physical one was proposed. Suggested was a method of designing a construction graph model which provides a most compact representation of the changes in the dynamic characteristics of the large space construction that occur in the course of its structural transformation.
