Abstract

Research of a three-dimensional motion of solid bodies of a constant and variable structure remains to one of central problems a dynamics of solid body and their systems, and also has the important value for applied problems of mechanics of space flight. In-process investigates a solid body of a variable structure with desired laws of a modification of moments of inertia. Equations of motion of a solid body of a variable structure are injected on the basis of a formalism of Hamilton. On the basis of the inferred equations the mathematical model of motion of a solid body of a variable structure in canonical variables Andyae-Deprit is under construction. For the analysis of dynamic it is carried out analytical and a numerical modeling of motion of a body. Existence of chaotic conditions in a system is displayed on the basis of method of Melnikov-Wiggins. Outcomes of activity can be used for the analysis and synthesis of conditions of an attitude of a space vehicle on the active legs with a modification of a mass.
